INTRODUCTION
ABOUT THE T 755
Though the T 755 is among the most technically sophisticated A/V receiver,
we worked hard to make it one of the most musically transparent home-
theater components available as well; this is what we mean by NAD’s “Music
First” design philosophy. Here are just few examples:
• The T 755 uses NAD’s proprietary Power Drive™ amplier technology
for all channels to preserve accurate, linear reproduction regardless
of the loudspeaker. This uniquely ecient power-supply topology
provides the real-world benets of high dynamic power that remains
uncompromised by low-impedance speakers. The result is dynamic,
detailed,”un-receiver-like” sound in stereo and multi-channel modes
alike. NAD’s exclusive Soft Clipping™ circuitry further enhances sound
quality and dynamic potential.
• High-performance components used throughout the receiver’s analog
audio circuits to maximize quality from all sources, including multi-
channel analog sources such as DVD-Audio and SACD.
• Preamp output (all channels) and main-amp input jacks make potential
expansion as exible as possible.
• Zone pre-amp and video feed with assignable 12 V DC trigger control.
• A Second set of Speaker terminals (Speakers B) for remote listening.
• An RS-232 port for advanced zone control and software update through
a Windows® compatible PC.
• Gold-surfaced connectors are employed throughout to ensure
maximum signal integrity.
E.A.R.S. AND DIGITAL SURROUND
A key element of the T 755’s unique musical aptitude is NAD’s proprietary
Enhanced Ambience Recovery System (EARS). In sharp contrast to many
“ambience-synthesis” music-surround modes, EARS exploits the T 755’s
substantial DSP power to route the ambient content that is “encrypted” in
virtually all natural-acoustic recordings to the appropriate main, center and
surround speakers, without resorting to articially generated reections
or regeneration. EARS’ natural ambience yields a subtle but exceptionally
eective surround mode that naturally enhances the spatial presentation in
a fashion suitable for serious music listening.
Dolby Pro Logic IIx Music and DTS Neo:6 Music modes can also create
enjoyable experience from 2-channel sources.
On the digital side, the T 755 combines extraordinarily high-speed DSP
processing employing one of the most advanced high-speed DSP “engines”
available, with fully 24-bit, 192 kHz-sampling-capable D/A converters for
all channels. A single, high-precision master clock synchronizes all digital
circuits to eliminate the timing errors (jitter) that otherwise compromise
sonics. The result is legitimately state-of-the-art surround decoding from
Dolby Digital and DTS sources, and 6.1/7.1-channel reproduction, with
genuinely superior sound quality in all modes.
EASE OF USE
Despite the eort NAD has invested in the T 755 A/V Receiver’s sonic
performance, we expended no less in making it powerfully easy to use.
Its design is uniquely simple for so sophisticated a component, and the
HTR 3 universal remote control is equally understandable, as are the T 755’s
own front-panel and on-screen displays. Its simple yet powerful system
of “presets” permits you to ne-tune your listening setup for dierent
conditions, sources, or listeners, and to recall these multiple parameters
with a single key press.
INTEGRATION
The T 755 A/V Receiver oers extensive, exible system-integration options
through its congurable DC trigger outputs and input, and its standard-
protocol IR communications links. The DC trigger outputs can be assigned
to Main, Zone and Source Setup locations.
ZONE
The T 755 A/V Receiver is equipped with a congurable Zone 2 that makes
full use of video and pre-amp level audio outputs. The ZR 4 remote control
will allow you complete access to Zone 2 applications including access to
volume On/O and all sources inputs.
RS 232
Flexible system conguration is possible with the RS-232 interface and
NAD’s proprietary Windows® compatible software. We are also certied
partners with AMX and Crestron and fully support these external devices.
This interface allows complete remote control of the T 755 from any remote
location via the PC. Complete remote control functionality is available to
the user by interface software. See your NAD audio specialist for further
information.
UPGRADABILITY
The T 755 A/V Receiver permits exible system growth via individually
accessible pre-out and main-in jacks for all channels. We have made the
more likely scenario of software upgrades easy to accomplish via the high
speed RS-232 port on the rear panel of the T 755. Owners who register
their T 755 on our international web site www.NADelectronics.com will be
advised of updates. Some of these may be free of charge, and some may
require royalty payments depending on the type of upgrade. The advanced
user will be able to perform these upgrades by downloading les from our
web site, via e-mail and installing them by connecting the T 755 to a PC.
Alternatively the dealer from whom you purchased your T 755 should be
able to assist in performing these upgrades.
ABOUT THE HTR 3 SYSTEM REMOTE CONTROL
Packed with your T 755 is the NAD HTR 3 remote control, a full-system
remote especially designed for easy use and understanding. Be sure to read
the section “Using the HTR 3 Remote Control”, to familiarize yourself with
the remote’s layout and operations before proceeding to setup your T 755.
You may opt to use your HTR 3 as your primary way to command your
entire AV system. The HTR 3 can be employed to operate additional NAD or
other-brand components such as a DVD/CD player, television, satellite/
HDTV tuner, VCR, or virtually anything else that operates via standard
infrared remote.

INTRODUCTION
GETTING STARTED
WHAT’S IN THE BOX
Packed with your T 755 A/V Receiver you will nd
• An AM loop antenna.
• A FM ribbon-wire antenna with balun.
• A removable AC cable (if you wish, any IEC-standard AC cable of suitable
wattage may be substituted).
• The HTR 3 remote control with 4 (four) AAA batteries.
• The ZR 4 zone remote control with 3V CR2025 battery.
• This owner’s manual.
SAVE THE PACKAGING
Please save the box and all of the packaging in which your T 755 arrived.
Should you move or otherwise need to transport your T 755, this is by far
the safest container in which to do so. We’ve seen too many otherwise
perfect components damaged in transit for lack of a proper shipping
carton, so please: Save that box!
CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to both
sides and behind), and that will provide a clear line of sight, within 23 feet/7
meters, between the T 755’s front panel and your primary listening/viewing
position—this will ensure reliable infrared remote control communications.
The T 755 generates a modest amount of heat, but nothing that should
trouble adjacent components.
It is especially important that sucient ventilation be provided. If you are
contemplating on locating the T 755 within a cabinet or other furniture,
consult your NAD audio/video specialist for advice on providing adequate
airow.
QUICK START
Packed with your T 755 is a Quick Start Guide that will guide you through
typical setup congurations in combination with your ancillary devices. The
Quick Start Guide also features the contents of your T 755 package as well
as start up procedures.
The T 755 is defaulted to the following settings:

NOTES
• Digital input will always take precedence over analog audio input even
if both are present.
• The T 755 is optimized for Component Video Output. Composite
video and S-video sources may be viewed in their native format or via
Component Video OUT.
DEALING WITH HUM AND NOISE
Hum and noise may sometimes prove a challenge in complex, multi-
channel audio systems. Note these considerations to help prevent hum and
noise problems:
• Power all your system’s audio component from AC outlets originating
from the same circuit of your house wiring. As far as possible, power
all audio components from the same outlet, or adjacent outlets on the
same circuit. It may be useful to power video displays (and computers!)
from outlets on another circuit, especially if that circuit is supplied from
the other “leg” of the house wiring.
• Do not bundle analog audio cables with AC power cables, or with
coaxial digital-audio cables. It is best if they cross at right angles if they
must be in close proximity.
• Employ high-quality, well-shielded audio cable throughout, and ensure
that all connections are secure.
• A pencil-eraser can be used to burnish copper- and gold-plated
contacts to ensure good, low-resistance contact; specialized contact-
cleaners can also be useful. Avoid unnecessary unplugging and
re-plugging since the gold (or copper) contact plating of typical cable
connectors, even very high-quality ones, is very thin and easily worn.
Track down hum/noise problems one component at a time, working
backwards from the A/V Receiver. That is
1 Connect the speakers to the A/V Receiver only, and check for hum.
2 Then connect one component only (a CD player, for example) alone,
with no other components connected and check for hum.
3 Connect additional components, one at a time, to the A/V Receiver and
check for hum.
At each stage, if hum/noise appears, examine the audio cabling and AC-
power routing of the new component. In some cases, moving the new
component’s AC cord to a dierent outlet, or installing a ground-lift (3-to-2-
prong adapter) on its power cord, will eliminate the hum.

1 IR IN/OUT: These mini-jacks accept and output remote-controlled
codes in electrical format, using industry-standard protocols, for use
with “IR-repeater” and multi-room systems and related technologies.
IR IN : This input is connected to the output of an IR (infrared) repeater
(Xantech or similar) or the IR output of another component to allow
control of the T 755 from a remote location.
IR OUT 2 : When connected to the IR IN of ancillary equipment, direct
the ancillary equipment’s own remote control to the T 755’s infrared
receiver to command or control the linked unit.
IR IN and IR OUT 3 : Connect the T 755’s IR IN to the IR OUT of ancillary
equipment. Connect also the T 755’s IR OUT 3 to another equipment
with IR IN feature. With this setup, the T 755 acts as an “IR-repeater”
allowing the equipment connected to the T 755’ s IR IN control or
command of the other equipment linked to the T 755’s IR OUT 3.
IR OUT 1 : In conjunction with IR IN, IR OUT 1 can be used as an “IR-
repeater” just like the IR OUT 3 as described above. It can also stand
alone as an IR OUT similar to that of IR OUT 2 function.
All NAD products with IR IN/IR OUT features are fully compatible with
the T 755. For non-NAD models, please check with your other product’s
service specialists as to their compatibility to the T 755’s IR features.
2 +12 V TRIGGER OUT: There are three congurable +12V TRIGGER
OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a
maximum current of 200 milliamps to auxiliary equipment such as a
multichannel amplier or subwoofer. The centre conductor (hot) of the
3.5mm jack is the control signal. The outside conductor (shield) is the
ground return-path.
TRIGGER IN accepts 12V Trigger output of compatible components such
as power controllers and home automation devices.
TRIGGER OFF/AUTO. When at AUTO position, the T 755 selects the 12V
Trigger Input to turn ON (if so assigned at the “Trigger Setup” menu) and
at the same time disables the HTR 3 and ON/OFF function of the front
panel. When set to [OFF] position, the trigger input is disabled.
See discussion on “TRIGGER SETUP” at the “SETUP MENU” literature for
guidelines on how to congure TRIGGER IN/OUT.
WARNING
If Auto Trigger IN at Trigger Setup menu is assigned to “Main” or “All” and
the TRIGGER switch is set to “AUTO” mode, the Power button in the front
panel as well as the corresponding ON/OFF function keys in the HTR 3
remote control will be disabled eectively handing this function to an
external controller. Switch TRIGGER to”OFF” to maintain normal power
ON/OFF function procedures.
3 SOFT CLIPPING: Enables NAD’s proprietary Soft Clipping circuitry on
all channels. At [ON] position, Soft Clipping gently limits the output of
the T 755 to minimize audible distortion should the A/V Receiver be
over-driven. Soft Clipping may simply be left ON at all times to reduce
the likelihood of audible distortion from excessive volume settings.
However, for critical listening and to preserve optimum dynamics, you
may wish to defeat it by setting this switch OFF.
4 FM, AM ANTENNA INPUT: The supplied wire “dipole” FM antenna will
connect to the FM connector using the supplied “balun” adapter. It will
usually work best when mounted on a vertical surface such as a wall,
with arms fully outstretched forming a horizontal “T” perpendicular to
the origin point of the signal.
Connect the supplied AM loop antenna to these terminals. If an external
AM antenna is used, make connections to the AM and GND terminals
in accordance with the instructions supplied with the antenna. See also
section about “LISTENING TO RADIO”.

processor. Connect the T 755’s AUDIO 3 IN/VIDEO 3 IN or AUDIO 4
IN/VIDEO 4 IN jacks to the component’s corresponding output.
The signal present at these T 755 AUDIO/VIDEO OUT jacks is determined
by the source last selected via the front panel Source keys or the HTR 3’s
input select keys with the exception of Source 3 or Source 4. There will
be no output when Source 3 (Audio 3 IN/Video 3 IN) or Source 4 (Audio
4 IN/Video 4 in) is the selected source input. This prevents feedback
through the recording component thereby preventing possible
damage to your speakers.
11 MONITOR (S-VIDEO, VIDEO): Connect to video input of the monitor/
television using quality dual-RCA and/or S-Video cables designed for
video signals. In general, the S-Video connection is superior and should
be used if your TV/monitor provides the corresponding input.
12 ZONE 2: Sends zone selected audio and video output sources to the
corresponding audio and video input of another separate zone. Use
high quality patch cables to reduce noise pickup over long distance
runs. For a better understanding of zone settings, study below the
section on “ZONE CONTROLS” of the “MAIN MENU” discussion as well as
the item on “ZONE SETUP” under the “SETUP MENU” literatures.
13 7.1 CH INPUT: Connect to the corresponding analog audio outputs of a
multichannel source component such as a DVD-Audio or multichannel-
SACD player or external multichannel decoder (disc copy protected
formats only allow analog signal transfer). Typically, these sources will
produce 5.1-channel output, in which case the Surround Back jacks are left
unconnected. The signals present at these jacks may be heard by selecting
Source 7 (7.1 Channel Input is defaulted to this Source).
There is no bass-management or other processing (other than master-
volume control) available to this 7.1 Channel Input. While the multi-
channel audio outputs of a DVD-Video player can be connected to
these jacks, using the T 755’s own Dolby Digital and DTS decoding and
digital-analog converters via a digital connection will usually produce
superior results.

PRO LOGIC PLII
Dolby Pro Logic II is a more recent evolution of the original Dolby Pro Logic surround processing that
yields more stable imaging and full bandwidth sound to the rear channels in Movie mode, oering
sound that is more similar to Dolby Digital decoding.
PRO LOGIC IIx
Dolby Pro Logic IIx processes both stereo and 5.1 signals into a 6.1 or 7.1 channel output. At Dolby
Pro Logic IIx, you can choose PLIIx Movie or PLIIx Music modes to tailor your listening experience
to the source material. Dolby Pro Logic IIx surround processing yields more stable imaging and
full bandwidth sound to the rear channels in Movie mode oering sound that is more similar to

possible to use the T 755 as a pre-amplier to external power ampliers for some or all channels.
NEO:6
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround
with output to front left/right, center and discrete left/right surround channels plus subwoofer
(assuming these are present in the current “Speaker Conguration”). The T 755 provides two DTS Neo:6
variations - CINEMA and MUSIC. See also section about “ADJUSTING LISTENING MODES” below.
EARS
Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD
surround processing with signals output to the front left/right, center and discrete left/right surround
channels, plus subwoofer (assuming these are present in the current “Speaker Conguration”). EARS
does not employ the surround back speakers (if any).
EARS extracts the natural ambience present in nearly all well-produced stereo recordings. It does not
synthesize any ambience or other sonic elements and thus remains truer to the sound of the original
musical performance than most other music-surround options.
Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly
natural and believable ambience from nearly all “natural-acoustic” stereo recordings. Typically, these
include classical, jazz, and folk genres as well as numerous examples from others. Its virtues include
realistic, stable “front-stage” sonic imaging and spacious but unexaggerated ambient “virtual acoustics”
that remain faithful to the original recording.
ENHANCED STEREO
All recordings reproduced in stereo via the maximum speaker complement congured in the current
“Speaker Conguration”. Enhanced stereo can be useful for maximum volume from all channels or for
multi-speaker background music (cocktail party) listening. For this mode, Front, Center, Surround and
Back speakers can be turned ON/OFF as desired.
ANALOG BYPASS
All analog signals remain in the analog domain without analog-to-digital conversions. At Analog
Bypass, the DSP circuitry is bypassed but full tone control functions remain. “Bass management” or

The T 755 has nine analog audio inputs including 7.1 input. These analog inputs - Audio 1, Audio 2,
Audio 3, Audio 4, Audio 5, Audio 6, Audio Front, Audio MP and 7.1 Input can be variably assigned to
each Source.
Scroll to “Analog Audio” and then press [ ] to select and assign an analog audio input to the particular
Source. There are three choices – Audio, 7.1 Input or O.
When “Audio” is chosen, press [ ] and then [ ] keys to select and assign the desired audio input
– 1 to 6, Front and MP.
Select “7.1 Input” to choose the audio signal fed to “7.1 Channel Input”. If “O” is selected, no incoming
analog audio signal is selected by the particular Source.
NOTE
An incoming digital signal present at the assigned digital input will always take precedence over the
assigned analog audio input, even if both are present. To maintain the analog audio input for the
particular Source, select “O” at the “Digital Audio” setting of the same ”Source” menu.
GAIN
Gain adjustment allows all sources to play back at the same volume so you don’t need to adjust the
volume every time a new source is selected. It is generally preferable to reduce the level of the loudest
source rather than making louder the softer sources.
Scroll to “Gain”, press [ ] and then [ ] to step through the desired level from -12dB to 12dB.
DIGITAL AUDIO
To take advantage of the T 755’s high performance surround and digital audio circuitry, it is advisable
that its Digital Audio inputs are selected.
There are two types of Digital Audio input for the T 755: Optical and Coaxial. A third option is “O” whereby
no incoming digital audio signal is selected by the particular Source.
The desired digital audio input for a particular Source can be selected by scrolling to “Digital Audio”, press
[ ] and then [ ] to step through the desired digital input source. After nalizing which type of Digital
Audio input is desired, press [ ] and then [ ] again to select the specic Digital Audio input.
There are seven Digital Audio inputs selectable for the T 755. They are the following
Optical Optical 1, Optical 2, Optical 3, Optical Front
Coaxial Coaxial 1, Coaxial 2, Coaxial 3
NOTE
An incoming digital signal present at the assigned digital input will always take precedence over the
assigned analog audio input, even if both are present. To maintain the analog audio input for the
particular Source, select “O” at the “Digital Audio” setting of the same “Source” menu.
VIDEO
There are four types of video input a particular Source could be assigned. These are HDMI, Component,
S-Video and Video inputs. A fth option is “O” wherein the particular Source is prompted not to select
any Video input.
Navigating through the Video input selections involve a combination of pressing [ ] and then [ ]
to step through the selections. The following are the assignable Video inputs
HDMI HDMI 1, HDMI 2, HDMI 3
Component Video Component 1, Component 2, Component 3
S-Video S-Video 1, S-Video 2, S-Video 3, S-Video 4, S-Video 5, S-Video Front
Video Video 1, Video 2, Video 3, Video 4, Video 5, Video Front
NOTE
An audio input and video input should always be associated to a selected Source setting to ensure audio and video
output. If “O” is selected for any of the Analog Audio, Video or Digital Audio settings, there will be no corresponding
audio or video for the associated Source. For example, if the selected Video setting for a particular Source is
Component 1 and both Digital and Analog Audio are set to “O”, only video output will be available but no audio.
Ideally, when the selected Video input is Component 1, it follows that the Digital Audio input is set to Optical 1 or any
of the digital inputs. Refer also to the QUICK START section under the INTRODUCTION – GETTING STARTED page.

ABOUT VIDEO FORMATS
For many years, there was only one type of video format used. Composite video signals include the
Luminance (black & White) and Chroma (color) signals combined on one wire. S-Video uses separate
wires in a single cable for Luminance and Chroma signals. Component Video goes a step further
with separate cables for Luminance and the two elements of Chroma. For NTSC (America, Japan)
as well as PAL signals(Europe, Asia) these are labeled Y, Cr, Cb. Television studios use the Component
Video format to keep these signals separate in order to maintain the best quality. As consumer video
equipment has improved this higher quality format has been included.
VIDEO FORMAT CONVERSION
The T 755 is equipped with a Video Format Converter. This allows for a simplied video connectionbetween
the T 755 and your TV Monitor when using multiple video formats such as Composite (CVBS), S-Video, and
Component (YUV). This format change is accomplished by encoding the analog video signal intoa digital
signal using a very high quality digital encoder to maintain the best possible picture quality. Once in a
digital format, it can be decoded into any of the three standard analog video formats.
It is suggested that you select the highest quality video format available on your TV Monitor and utilize this
for your Monitor OUT connection from the T 755 to the TV Monitor. In most cases this will be Component
Video, but on some older TV’s S-Video may be the best quality connection. See also the item “3 COMPONENT
VIDEO 1-3, COMPONENT VIDEO OUT” under “Identication of Controls – Rear Panel” discussions.
NOTES
Video signals are converted between all three formats:
• Composite, S-video and Component Video.
• All three monitor outputs will always be active no mater what the source format is.
• OSD menu is always available on all three output formats.
A/V PRESET
A particular Source can be assigned a stored Preset. The parameters set up in the selected Preset
number will be adopted into the particular Source it is assigned (Please refer to the separate section on
“A/V PRESETS” for further understanding of Preset settings).
Scrolling to “A/V Preset” and by pressing [ ] and then [ ] keys, a Source could be assigned a
Preset number ranging from Preset 1 to 5.
If it is desired not to assign the particular Source a Preset setting, select “None”.
TRIGGER OUT
The Trigger Out for a particular Source is dependent on the congurations done in a separate menu on Trigger
Setup (See “TRIGGER SETUP” below). If all three available Trigger outputs are assigned to “Source Setup” in the
separate “Trigger Setup” window, a particular Source can have the following Trigger Out combinations
Trigger Out 1 2 1 + 2 3 1 + 3 2 + 3 1+2+ 3
These combinations are dependent on the assignment of “Source Setup” for “Trigger 1 Out, Trigger 2
Out or Trigger 3 Out” at the Trigger Setup menu.
Another option is “O” whereby the particular Source is not assigned any Trigger Out.
For “Trigger Out” to become enabled and assignable at “Source Setup (Normal View)” menu, make sure
to carry out or note the following beforehand
• In the separate “Trigger Setup” menu, assign “Trigger 1 Out, Trigger 2 Out or Trigger 3 Out” to
“Source Setup”.
• “Trigger Out” will not appear as an option at the Source Setup (Normal View) menu if at the
separate “Trigger Setup” menu, “Trigger 1 Out, Trigger 2 Out or Trigger 3 Out” are all assigned to
“Main” or “Zone 2” without a single “Trigger Out” port allocated to “Source Setup”.
SOURCE SETUP (TABLE VIEW)
The Source Setup (Table View) reects the settings made in the Source Setup (Normal View) menu. All
the Source settings are summarized and displayed in tabulated form in the Source Setup (Table View).
Navigating through the Source Setup (Table View) via a combination of [ ] and then [ ] keys,
one will have the benet of directly changing the settings for “Audio, Video, Preset, Trigger and Source
Name” without going back to the Source Setup (Normal View) menu.

iPod SETUP
The iPod Setup menu allows you to preset the following associated settings when iPod is the selected
source:
Enabled: Select “Yes” to enable iPod as a Source or “No” to disable it.
Auto: Select “Yes” to automatically enable and connect the iPod player docked in the linked NAD
iPod docking station when Source 5 (the default iPod source allocation in the T 755) is selected.
Select “No” if you do not want for the iPod connection automatically connected.
Menu Timeout: Set the time for the OSD to revert to the “Now Playing” display when the iPod
menu has been left idle (no scrolling or navigation being done) for the specied time out time. For
the “Now Playing” OSD to be shown, there should be a song paused or being played before going
to the iPod menu. You can set the “Menu Timeout” between the range 5s to 60s at 5s increments. If
you do not want for the menu to timeout, select “O”.
SPEAKER SETUP
After connecting all ancillary sources and other combinations, the Speaker Setup menu will guide
you on how to manage and setup your speakers in order to achieve optimum sound acoustics in your
listening environment.
The following are the Speaker Setup Menu sections.
AUDYSSEY SETUP
It has been shown that many, if not most, surround sound systems are not accurately congured and setup.
This requires special knowledge and instrumentation that the average person probably doesn’t possess.
The T 755 has the capability to automatically setup your own unique Home Theatre’s speaker system.
This is achievable through the T 755’s Audyssey Setup feature along with the sophisticated digital
electronics built into your unit.
The installation of your new T 755 is greatly simplied by Audyssey Setup with the end result of
delivering the best quality sound possible given the type of speakers you have as well as your listening
room’s dimensions.
Audyssey Setup takes up only a fraction of time to run compared with setting up your speakers
manually and then achieve results that rival other expensive test and setup measuring devices.
The following measurements are performed:
• Detection : Speaker conguration is detected including the number of surround speakers and
whether a subwoofer and center channel is connected.
• Size : T 755 crossover is set based on each channel’s signal handling capability and the subwoofer
crossover is automatically set.
• Level : SPL of each speaker is matched within 1dB at the microphone position.
• Distance : is accurately set to within 1 foot (30 centimeters) of the microphone for each speaker
position.
• Polarity : the setup program will detect and notify the user if any speakers are connected
improperly. Incorrect polarity can ruin the illusion of realism oered by surround sound.
This is a one-time setup, unless speakers are moved or changed, in which case Audyssey Setup should
be performed again.
OPERATION
USING THE T 755 SETUP MENU
19
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
MEASUREMENT IS THE FIRST STEP
Connect the Audyssey microphone jack into the front panel’s MP/MIC input and the Audyssey Setup
wizard will guide you through a simple step-by-step conguration.
The sound at your main listening position is setup using the supplied Audyssey microphone. A special
test tone is sent to each speaker and the data is memorized by the T 755. The duration of setup may
take some time depending on the number of speakers. After the measurements, Audyssey calculates
the ideal system response for your particular room and speaker setup.
If some inconsistencies or discrepancies are detected during the Audyssey setup, the process
maybe interrupted or the problem is shown in the particular setup window. A notice screen is
correspondingly displayed. After following and undertaking the displayed instructions, re-start the
Audyssey setup again. When the measurements are nalized, Audyssey calculates the ideal system
response for your particular room and speaker setup.
NOTES
• The test tone emitted during measurement is loud. This maybe bothersome for you and may aect
as well your other household members and even your neighbor.
• The mention of “Back Right” and “Back Left” refer to your external amplier’s corresponding “Back
Right” and “Back Left” speakers (if any) as interfaced with the T 755. The Audio PRE- OUT makes it
possible to use the T 755 as a pre-amplier to external power ampliers for some or all channels.
It is recommended that you take full advantage of the T 755’s Audyssey Setup feature for your speaker
setup. However, if you desire to setup your speakers manually or if you already had run Audyssey Setup
but would like to make adjustments, the following sections on Speaker Conguration, Speaker Levels
and Speaker Distance can also be followed and implemented.
NOTE
During manual setting of your speakers, previously calibrated Audyssey settings could be retrieved
by re-adjusting back the altered congurations as highlighted by an asterisk.
SPEAKER CONFIGURATION
Every surround-sound system requires “bass-management” to direct low-frequency content from any
or all channels to the speakers best able to reproduce it. For this function to operate correctly, it is
important that you correctly identify your speakers’ capabilities. We use the terms “Small” and “Large”
(and “O”), but note that physical size may be irrelevant.
• A “Small” speaker is any model, regardless of physical size, that lacks signicant deep-bass response,
that is, below about 80 Hz.
• A “Large” speaker is any full-range model, that is, one with deep-bass response
• An “O” speaker is one that is not present in your system. For example, you might not have any
surround-back speakers installed; in that case, you would set the “Back” setup item to “O”.

The Speaker Conguration is “global”; that is, it remains in force with all inputs and in all listening
modes. However, speaker settings are part of the T 755’s Preset system. Consequently, multiple speaker
settings can be stored for easy recall as dierent types of recordings or listening modes require.
Speaker Conguration can be managed and adjusted by pressing a combination of [ ] and then [ ]
keys. Set “Front”, “Center”, and “Surround” to “Large”, “Small” or “O” as your subsystem’s speakers require.
The “Back” speakers can either be one or two speakers. Set “Back” to either 1 or 2 speakers as per
availability. Set “Subwoofer” to “On” or “O”, selecting “On” only if you have a subwoofer connected to
the T 755’s SUBW1 or SUBW2 output jack.
NOTE
The mention of “Back” speakers refer to your external amplier’s corresponding “Back Right” and
“Back Left” speakers (if any) as interfaced with the T 755. The Audio PRE- OUT makes it possible to
use the T 755 as a pre-amplier to external power ampliers for some or all channels.

ENHANCED BASS
When the subwoofer is set to ON and one or more speakers are set to “Large”, Enhanced Bass is also
available. Normally, with speakers set to “Large” the subwoofer is not active. The Enhanced Bass option
allows full range operation of the speakers with the additional bass contribution of the subwoofer. This
feature is particularly useful when one wants to experience maximum bass output. Please note that
due to acoustic cancellation eects, the bass response may be uneven when using this setting.
You can set Subwoofer to “On” even with “Large” front speakers, in which case bass content from any
channels set to “Small” will be routed to both the subwoofer and to the front speakers; LFE-channel
signal will pass only to the sub. In most subwoofer-equipped systems, setting front speakers to “Small”
is usually the better option.
All the speakers’ low frequency content can be directly adjusted within the range 40Hz to 200Hz.
NOTE
The congurations set forth at “Speaker Setup” are carried over whenever it is enabled during A/V
Preset setting. Please see also the section “A/V PRESETS” for reference.
SPEAKER LEVELS
Adjusting the relative balance of your system’s loudspeakers ensures that surround-sound recordings,
whether music or lm, will present the balance of eects, music, and dialog that the artists intended.
Additionally, if your system incorporates a subwoofer it establishes a correct relationship between the
volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic
elements.
USING AN SPL METER
It is quite practical to perform the T 755 level setup routines “by ear”, and careful work will produce
acceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter,
such as Radio Shack part number 33-2050, makes this task easier, more accurate and more repeatable.
Ownership of such a meter could prove a valuable audio tool. Your NAD audio specialist may be able
to help you with temporary use of a meter.
The SPL meter should be placed at the primary listening position, at approximately the height of
the seated listener’s head. A tripod is helpful but with a little duct tape almost anything — a pole
lamp, music-stand, or ladder-backed chair, for example — can do as well. Just be sure that no large
acoustically reective surfaces obstruct or are near the microphone element.
Orient the meter with its microphone (usually at one end) pointing straight up toward the ceiling (not
toward the speakers) and ensure that “C” weighting scale is selected. Set the meter to display 75 dB
SPL. On Radio Shack meters, this necessitates either setting the meter to its 80 dB range and taking
your readings at the -5 point or selecting the 70 dB range and reading at the +5 point.
SETTING SPEAKER LEVELS AT TEST MODE
While at “Speaker Levels” menu, press the HTR 3 remote’s “Test” key activating the T 755’s Speaker Levels
balancing test signal. You will hear a “surf” sound as you step through your speakers (“test” appears to
the right side of the current speaker), beginning with the Front Left. If you do not hear the test signal,
check your speaker connections or your “Speaker setup” menu settings.
Use the remote’s [ ] keys to adjust the loudness of the noise output from the currently playing
channel to the required level (it’s usually simplest to begin with the Front Left). As you cycle the test
signal around the speakers, the OSD will highlight the currently playing channel. The “level oset”
reading on the right will change by 1 dB increments; ±12 dB adjustment is available. Press [ENTER] to
adjust the next speaker.
NOTE
If you are balancing levels “by ear”, choose one speaker—usually the center— as a reference and
adjust each of the others in turn to “sound as loud” as the reference. Be sure that you remain in the
primary listening position while balancing all channels.
OPERATION
USING THE T 755 SETUP MENU
22
ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA РУССКИЙ
To produce the same SPL meter reading (or subjective loudness), use the remote’s [ ] keys to
adjust each speaker.
NOTES
• All speakers must be in their nal locations before level-setting.
• Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to
its highest-possible frequency if you are using the T 755's Subwoofer output. Final subwoofer-level
adjustment “by-ear”, using music and lm sound material, is frequently useful.
• Due to the eects of room acoustics, matched-pair speakers (front; surround; back) will not always
calibrate to exactly the same level oset readings.
You can exit “Test” mode at any time by pressing the [ ] key twice, bringing you back to “Speaker
Setup” menu.
SPEAKER DISTANCE
Your system’s speaker distance settings are a subtle but important renement of your setup. Informing
the T 755 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct
delays, optimizing imaging, intelligibility and surround-sound ambience. Enter your dimensions with
precision within about 1 foot (30 cm).
SETTING SPEAKER DISTANCE
While at “Speaker Distance” menu, use the [ ] keys to individually set Front Left, Center, Front Right,
Surround Right, Back, Surround Left and Subwoofer to the distance measuring from your principal
listening position to the front surface of their corresponding loudspeakers. Distance can be set up to
30 feet or 9.1 meters.
Distance can be displayed as feet or meters selectable at the “Unit of Measure” item.
ADJUSTING THE VOLUME
In addition to the Volume knob, use the HTR 3’s [VOL ] to adjust the “master volume” of the T 755
raising or lowering the channels altogether. A momentary keypress will change the master volume by
1 dB increments. If you hold down [VOL ] the master-volume change will “run-on” until the key is
released.
Since recordings vary considerably in overall average level, there is no imperative to listen at any
particular master-volume setting. A setting of -20 may sound “as loud” from one CD or DVD as -10 does
from another.
The T 755 will power-up from Standby mode at whatever master volume setting was last used;
however, if the prior setting was greater than –20 dB, the T 755 will power up at –20 dB. This prevents
inadvertently beginning a session at excessive volume.
MUTING THE SOUND
Use the HTR 3’s “Mute” key to silence all channels completely. Muting is always available regardless of
the source or listening mode selections.
NOTES
• Changing input or listening-mode selections does not release muting.
• Adjusting the master-volume upward via the HTR 3 or the front-panel knob automatically releases
the mute function.

ADJUSTING CHANNEL LEVELS “ON THE FLY”
You can make changes to the relative levels of center, surround and subwoofer outputs without
having to go into the “Speaker Levels” menu. This is very convenient in circumstances like increasing
(or tone down) a lm’s dialog level by rising (lowering) the center channel or reducing excessive deep
bass (or enhance deep bass) by lowering (rising) the subwoofer level.
Use the HTR 3’s [SURR], [CENT] and [SUB] keys for direct-access level adjustment of these channels over
a range of ±6dB.
The surround back channels (if any) adjust in lockstep with the surround channels.
NOTE
Level settings adjusted “On the Fly” are added or subtracted to the setup levels established at the
T 755 level-calibration routine as invoked by the HTR 3 “Test” key. However, selecting any Preset
will revert the channel levels to those stored in the preset. It will also take T 755 o the levels set via
Audyssey Setup.
ZONE SETUP
The Zone feature allows one to simultaneously experience in dierent zones of the house multiple
sound and applicable video sources from all enabled Sources as well as from Front Input, Media Player
and Tuner.
VOLUME
Zone 2 have Fixed and Variable volume control. When set to “Variable”, the Zone 2 Volume is directly
adjustable using [ ] cursor keys of the HTR 3 or [VOLUME ] keys of ZR 4.
On the other hand, if Volume is set to “Fixed”, the Zone 2 Volume is set to a preset dB level and
thereafter the zone’s volume can be varied via the volume control of the separate amplier it is fed
into.
See discussion also on “ZONE CONTROLS” at the Main Menu.
NOTE
The ZR 4 remote control will only control Zone 2 applications.
TRIGGER SETUP
The T 755 features three congurable +12V DC Trigger Output that can be used to activate a
component or system it is fed into. A Trigger Input is also available to turn on the applicable link it is
associated to. Use a combination of [ ] or ENTER and [ ] keys to navigate through the Trigger
Setup menu parameters.
TRIGGER OUT
Triggers are low voltage signals used to turn on/o other compliant devices. The T 755’s three +12V DC
Trigger Outputs (Trigger 1 Out, Trigger 2 Out and Trigger 3 Out) are dependent on which mode they
are associated with. There are three choices where +12V DC output can be assigned and these are
– Main, Zone 2 and Source Setup.
Main: +12V DC is available at the assigned Trigger Out when the T 755 is at powered state.
Zone 2: When Zone 2 is at powered state, +1 2V DC is available at the assigned Trigger Out.
Source Setup: If Trigger Output is linked to “Source Setup”, +12V DC is available at Trigger Out
whenever the particularly assigned Source is selected. Please see also separate discussion about
“TRIGGER OUT” under the “SOURCE SETUP (NORMAL VIEW)” section.
OPERATION

DELAY
The availability of +12V DC at Trigger OUT can be regulated. If it is desired that +12V DC is available
without delay the moment Trigger OUT is linked to its assigned setting, set Delay to 0s. Otherwise, one
can select through a delay time of 1s to 15s.
AUTO TRIGGER IN
Auto Trigger IN allows external system controllers to toggle the associated section of the T 755 from
“Standby” to “On” and vice versa. When the TRIGGER switch at the rear panel is set to ON, a +12V DC
input at Trigger IN will power ON the section where Trigger IN is assigned,
Main: From standby mode, the T 755 is powered ON when +12V DC is applied at Trigger IN.
Zone 2: Zone 2 is turned ON whenever +1 2V DC is present at Trigger IN.
All: Main and Zone 2 as described above will all be activated given a +12V DC input at Trigger IN.
WARNING
If Auto Trigger IN at Trigger Setup menu is assigned to “Main” or “All” and the TRIGGER switch is set
to “AUTO” mode, the Power button in the front panel as well as the corresponding ON/OFF function
keys in the HTR 3 remote control will be disabled eectively handing this function to an external
controller. Switch TRIGGER to “OFF” to maintain normal power ON/OFF function procedures.
See also item “2. +12 V TRIGGER OUT, TRIGGER IN, TRIGGER AUTO/OFF” of REAR PANEL discussion as well
as the “TRIGGER OUT” discussion under “SOURCE SETUP (NORMAL VIEW)”.
LISTENING MODE SETUP
The T 755 has various listening mode options and is mostly congurable. These are provided to
reproduce a variety of sound eects depending upon the content of the source to be played. Use a
combination of [ ] or ENTER and [ ] keys to congure the following settings.
NOTE
The mention of “Back” speakers refer to your external amplier’s corresponding “Back Right” and
“Back Left” speakers (if any) as interfaced with the T 755. The Audio PRE- OUT makes it possible to
use the T 755 as a pre-amplier to external power ampliers for some or all channels.
LISTENING MODES
The audio format as detected by the selected Source can be automatically congured and processed
through the following options:
DOLBY DIGITAL
Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs
bearing the double-D symbol were recorded with up to 5.1 channels of digital signals, reproducing a
much better sound quality, with dynamic and spatial sound sensations that are much better than in
the previous Dolby Surround.
A Dolby Digital audio input can be congured relative to its format.
2 Channel: If the detected audio is a 2 Channel Dolby Digital signal, you can default it to one of
the following settings – Pro Logic, PLIIx Movie, PLIIx Music or None.
Surround: If the detected audio is a Surround Dolby Digital signal, you can default it to one of the
following settings –Surround EX, PLIIx Movie, and PLIIx Music, Stereo Downmix or None.
None: If “None” is selected, the Dolby Digital format will follow the “Digital” setting set forth at
“Other” option under this menu section. See discussion below about “OTHER”.

DOLBY DIGITAL EX
Using a Matrix decoder, this method creates the back channel (sometimes also called the “surround
center”) by means of signals on the left and right surround channels recorded in Dolby Digital 5.1,
reproduction being provided in Surround 6.1. This method should be selected with sources bearing
the (double-D symbol)-EX, recorded in Dolby Digital Surround EX.
With this additional channel you will experience improved dynamics and a better sensation of
movement within the sound eld. If media sources recorded in Dolby Digital EX are decoded with a
Digital EX decoder, the format is detected automatically, and the Dolby Digital EX mode is selected.
However, some media sources recorded in Dolby Digital EX can be detected as simple Dolby Digital
media sources. In this case Dolby Digital EX should be selected manually.
NOTE
Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of Pro
Logic, PLIIx Movie, PLIIx Music and Stereo Downmix modes.
DTS
The Digital Theater System Digital Surround (simply called DTS) is a multi-channel digital signal format
that can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are
5.1 channel media formats, discs bearing the “DTS” symbol are thought to provide better sound quality
due to the lower audio compression required. It also oers a broader dynamic, producing magnicent
sound quality.
A DTS input can be defaulted to one of the following options: - Neo:6 Music, Stereo Downmix or None.
If “None” is selected, the DTS signal will follow the “Digital” setting set forth at “Other” option under this
menu section. See discussion below about “Other”.
NOTE
Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of
Stereo Downmix and DTS Neo:6 surround modes.
OTHER
If “None” is selected above for any of the Dolby Digital 2 Channel, Dolby Digital Surround and DTS
options or if the audio input is an analog signal, this “Other” section will manage the default audio
format as per the “Digital” or “Analog” settings.
Digital: The detected digital input can be congured by way of one of the following options
- Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced Stereo, Stereo
Downmix and None.
Analog: If the audio input is an analog signal, the following are the surround modes the input
can be defaulted - Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced
Stereo, Analog Bypass and None.
NOTE
All these Listening Modes for “Dolby Digital”, “DTS” and “Other” can be directly changed by pressing

default. Settings of 75%, 50%, and 25% progressively reduce dynamic range, making soft sounds
comparatively louder while limiting the peak loudness of loud ones.
The 25% setting will yield the least dynamic range and is best for late-night sessions or other times
when you wish to retain maximum dialog intelligibility while minimizing overall volume levels.

DTS SURROUND MODES
The following are further descriptions about the DTS surround modes.
DTS ES EXPANDED SURROUND ™ DTS ES
This is a new multi-channel digital format which greatly improves the 360° spatial sensation of the
Surround impression thanks to the greater space expansion of the surround signals, providing high
compatibility with the conventional DTS format.
In addition to the 5.1 channels, the expanded DTS-ES Surround also oers the back surround (also
sometimes called the “surround centre”) in reproduction, providing a total of 6.1 channels. The
expanded DTS-ES Surround includes two formats, with two dierent methods of surround signal
recording, as follows:
DTSES™ DISCRETE 6.1
Since the signals of the 6.1 Surround channels (including the back channel) are completely
independent, it is possible to achieve the sensation that the acoustic image is moving about freely
among the background sounds, 360 degrees surrounding the listener.
Although maximum quality is achieved with sound tracks recorded using this system and reproduced
using the DTS-ES decoder, when played with a conventional DTS decoder, the back surround channel
is automatically downmixed in the surround right and surround left channels of the surround system,
in such a way that none of the signal components are lost.

USING THE T 755 SETUP MENU
27
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
DTS ES™ MATRIX 6.1
In this format, the additional signals of the back channel receive a matrix encoding and are inputted
into the right and left surround channels. During reproduction they are decoded to the right, left and
back surround channels.
Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1
format eect can also be achieved from sources with DTS-ES 5.1 signals.
Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in DTS-ES 6.1.
When a DTS-ES decoder processes a discrete DTS-ES 6.1 or in Matrix 6.1, these formats are
automatically detected and the Optimum Surround mode is selected. However, some DTS-ES Matrix
6.1 sources may be detected as DTS. In this case the DTS-ES Matrix mode should be selected manually
in order to reproduce them.
DTS NEO:6™ SURROUND
This mode applies the conventional 2-channel signals such as digital PCM or analog stereo signals to the
high precision digital matrix decoder used for DTS-ES Matrix 6.1 to achieve 6.1-channel surround playback.
DTS Neo:6 surround includes two modes for selecting the optimum decoding of the signal sources:
DTS NEO:6 CINEMA : This method is ideal for the reproduction of movies. The decoding takes
place by emphasizing the separation in order to achieve the same atmosphere with 2-channel, as
with 6.1-channel sources.
DTS NEO:6 MUSIC : Mainly recommended for music reproduction. The right and left front
channels do not pass through the decoder and are reproduced directly so there is no loss in sound
quality, and the eects of the right surround, left surround, central and back surround channels add
a natural sensation of expansion of the sound eld.
ENHANCED STEREO
Please refer to the same description about “ENHANCED STEREO” under the “LISTENING MODE” of the
Main Menu discussions.

LISTENING TO RADIO
The T 755’s internal AM/FM tuner oers very high quality sound from radio
broadcasts. The reception and sound quality will always be dependent to a
degree however on the type of antenna(s) used as well as proximity to the
broadcast origin, geography and weather conditions.
ABOUT ANTENNAS
The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-
antenna input using the included “balun” adapter and should be fully extended
to form a “T”. This folded-dipole antenna will usually work best when oriented
vertically, with the arms of its “T” fully outstretched and arranged perpendicular
to the origin of the desired broadcast. There are no rules however, and
experimenting freely with antenna placement and orientation may yield the
clearest sound and lowest background noise.
In areas of poor FM reception, an exterior FM antenna can improve
performance dramatically. If radio listening is important to you, consider
consulting an antenna installation professional to optimize your system.
The supplied AM “loop” antenna will usually provide adequate reception.
However, an exterior AM antenna can be used to improve reception.
Consult an antenna professional for more information.
ASSEMBLING THE LOOP ANTENNA
1 Rotate the outer frame of the antenna.
2 Insert the bottom edge of the outer frame into the groove on the stand.
3 Extend the antenna cord.
SELECTING THE RADIO

stations is muted.
Pressing the [TUNER MODE] button again (FM Mute FM Stereo icons on the
VFD are extinguished) allows distant and potentially noisy stations to be
received. Noise is reduced if the FM station signal level is less than the FM
Stereo threshold (since mono FM is inherently less noise-prone) though at
the sacrice of the stereo eect.
NOTE
One can store the same channel in two preset locations - one with
TUNER MODE On and another with TUNER MODE O.
ABOUT USER NAMES
You can assign an eight character “User Name” to each radio preset, which
will show in the front-panel readout whenever that preset is recalled.

ABOUT RDS
The Radio Data System (RDS) permits sending small amounts of digital
information using conventional FM radio broadcasts. The T 755 supports
two RDS modes, station-name (PS mode) and radio-text (RT mode). Not
every FM station incorporates RDS in its broadcast signal. In most areas you
will nd from one to several RDS-enabled stations, but it is by no means
impossible that your favorite stations will not be broadcasting RDS data.
VIEW RDS TEXT
When an RDS-enabled FM broadcast is tuned, after a brief delay the “RDS”
symbol will illuminate in the T 755’s front-panel readout and the readout’s
character section will show its station-name (PS) text: “ROCK101”, for
example.
Press the front-panel INFO key to toggle the readout between this and the
station’s radio-text (RT) readout, if any, which might scroll song- or artist-
name, or any other text of the station’s choosing.
ABOUT XM RADIO
The T 755 is “XM Ready” which means that with the addition of separately
sold XM Mini-Tuner CPC-9000 and XM Mini-Tuner Home Dock, it has
everything you need to listen to live XM. Everything else is built right in.
Just subscribe to the XM service and your T 755 will be ready to receive XM

and XM channels.
ABOUT DAB RADIO
Until now, analogue radio signals such as FM or AM have been subject to
numerous kinds of interference on their way from the transmitter to your
radio. These problems were caused by mountains, high-rise buildings
and weather conditions. With Digital Audio Broadcast (DAB), you can now
receive CD-like quality radio programs without any annoying interference
and signal distortion. DAB broadcasts use digital signals rather than
traditional analogue transmissions, thus providing clear high quality
reception. You get far more robust reception and virtually hiss or crackle
free sound with DAB as long as you are within a good coverage area.
With DAB, the listener can scroll through a list of available stations - then
instantly tune to the station of his choice. There is no need either to
remember channel frequencies. All broadcasts are selected by simply
selecting the service name.
The T 755 makes it possible for you to enjoy listening to DAB broadcasts.
The T 755 has a Digital Audio Broadcast (DAB) module socket on the rear
panel for adding a separately sold and NAD-specied outboard DAB
module – the NAD DAB Adaptor DB 1. All the control software for this
format is included; just plug-in the module and start enjoying the CD-like
quality sound and expansive content selection available with DAB.
CONNECTING THE DAB MODULE
Plug-in the other end of the DIN connector (supplied with your NAD DAB
Adaptor DB 1) from the DAB module’s output port into the corresponding
DAB module input socket on the rear panel of the T 755. Select DAB mode
on the T 755 by toggling the [AM/FM/DB] button in the front panel.
NOTES
• Please refer to NAD DAB Adaptor DB 1 installation guide for proper setup
connection of the DB1 with respect to the T 755.
• If there is no NAD DAB Adaptor DB 1 connected, the VFD will show
“Check DAB Tuner”.

TO VIEW VIDEOS LOADED IN YOUR iPod
Videos uploaded in your iPod can be viewed directly via the T 755. The
following are the steps
1 Make sure that the “TV Out” setting of your iPod’s Video Settings menu is
at “On” mode and appropriate “TV Signal” is chosen.
2 Video le selection and playback procedures are managed directly from
your iPod player and not through the T 755. You must exit completely from
the T 755’s Setup Menu or Menu Select OSD for you to be able to navigate
through your iPod player’s video playback menu options. A more direct way
is by going to the “iPod Setup” menu and set “Enabled” to “No”.
3 With the iPod dock’s S-VIDEO OUT and AUDIO OUT ports connected to
the T 755’s AUDIO/VIDEO 5 input or to any other assignable input, you
can now directly enjoy via T 755 your video selections as uploaded in
your iPod. Make sure that you select the correct “Source Number” of the
T 755.

SPECIFICATIONS
• Controls up to 8 devices.
• 44 function keys.
• Learns up to 352 commands.
• Records up to 44 macros with a maximum of 64 commands each.
• Congurable punch-through.
• Key illumination with programmable timeout.
• Upgradable.
• Contains pre-programmed library of NAD remote codes.
The NAD HTR 3 is ready to operate the T 755 A/V Receiver right out of the box, but it is really eight
remotes in one. Each of the 8 Device Selector keys at the top of the handset can call up a new “page”
of remote control codes to be transmitted by the remaining 44 keys. You may “teach” codes from any
infrared-remote controlled component, regardless of brand, to any or all of these.
Obviously, the most logical system is that you teach the codes from your DVD player to the [DVD]
Device Selector “page,” your television’s codes to the [TV] “page,” and so on, but there is no required
scheme: You may load any commands to any key on any page (see “Learning Codes From Other
Remotes,” below).
The HTR 3 is already preprogrammed with a full complement of commands for the T 755 A/V Receiver
on its [AMP] Device Selector page, and as well as with library commands to operate most NAD-brand
DVD or CD components on the corresponding Device Selector “pages.” These default commands are
permanent: Even if you teach the HTR 3 new commands to take their place, the underlying library
commands remain in place and can easily be recalled should you add an NAD component to your
system later (see “Delete Mode”, below).
Note: For use with the T 755, it should not be necessary to re-program any keys on the HTR 3 [AMP]
page. However, in order for the HTR 3 to control your specic NAD-brand components you may need
to load one or more dierent code-libraries (see “Loading Code Libraries,” below).
CONTROLLING THE T 755
The HTR 3 is divided into two main sections. Eight Device Selector keys at the top—[AMP], [DVD,]
[TV,] and so on—set the handset’s remaining keys to a “page” of commands to control a particular
component. A Device Select key determines only what component the HTR 3 will command; it does
not perform any function on the A/V Receiver. All of the remaining keys are function keys that can
“learn” control codes from virtually any infrared remote controller, allowing you to teach the codes of
your equipment, regardless of brand, to the HTR 3.
However, the HTR 3 is already preprogrammed to operate the T 755. All of the function keys on the
[AMP] Device Selector “page” perform T 755 functions. (The HTR 3 can also command many other NAD
components, from its [DVD,] [CD,] [TUNER,] and [CUSTOM] pages.)
It is important to note that certain HTR 3 keys perform dierent functions depending on the selected
Device Selector “page.” The color of the Device Selector key-labeling corresponds to the labeling of the
function keys. Most centrally, the black [AMP] Device Selector “page” corresponds to the black as well
as white input-select labeling above the numeric keys: When the HTR 3’s [AMP] Device Selector page
is active, these keys select the A/V Receiver inputs. Similarly, the purple [DVD] Device Selector “page”
corresponds to several purple labels, the green [TV] page to green labels, and so on.

ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
LEARNING CODES FROM OTHER REMOTES
Begin by positioning the HTR 3 “nose-to-nose” with the source remote so
the two devices’ infrared windows are about 2 inches apart.
• Enter Learning Mode: On the HTR 3, simultaneously press-and-hold for
3 seconds both a Device Selector key and the [RES] key (just below the
DISP key) until the Learn LED at the center of the HTR 3 turns steady
green.
• Press the HTR 3’s function key you wish to teach a command; the Learn
LED will turn amber.
• Press-and-hold the function key on the source remote: The HTR 3’s
Learn LED will icker amber for a second or two, then turn solid green.
The command is learned.
• Press the HTR 3’s Device Selector key again to exit the learning mode.
If the Learn LED does not icker amber you may need to vary the distance
between the remotes. If the Learn LED turns red rather than green, that
particular command of that source remote command could not be learned.
Example: Learning “DVD Pause”
Position the HTR 3 and your DVD player’s remote as described above.
• On the HTR 3, simultaneously press-and-hold [DVD] and [RES]; the Learn
LED turns steady green.
• Press the HTR 3’s Pause [ ] key; the Learn LED turns amber.
• Press-and-hold the corresponding Pause key of your DVD player’s
remote control; the HTR 3’s Learn LED ickers amber and then turns
solid green. The command is learned.
• Press [DVD] again to exit the learning mode.
CANCEL OPERATION
You can cancel conguring a key, by pressing the active Device Selector key
before the learn process is complete; the Learn LED will turn red.
PUNCH THROUGH
The HTR 3’s “punch-through” function allows you to retain a function key
from one Device Select “page” to another, so that, for example, the AMP
[SURR MODE] function might still control the T 755 when the DVD Device
Selector page is active.
NOTE
The HTR 3’s [VOL] keys are pre-programmed as “punched-through” for
all Device Select pages: [VOL] will operate the T 755’s master-volume
regardless of the currently selected device. The [SURR] [CENTER,] and
[SUB] Channel Volume controls similarly are pre-programmed as
punched-through.
To set a punch through, after entering the Learning Mode, and pressing the
desired key to be punched through, simply press the device key twice of
the device to punch through to. The status LED will turn green; press the
Device Selector key again to exit Learning Mode.
Example: Punch-through AMP [SURR MODE] key to the DVD “page”
• On the HTR 3, simultaneously press-and-hold [DVD] and [RES]; the Learn
LED turns steady green.
• Press [SURR MODE]; the Learn LED turns amber.
• Press [AMP] twice; the Learn LED turns green.
• Press [DVD] again to exit the learning mode.
COPY A COMMAND FROM ANOTHER KEY
You may copy a command from any HTR 3 key to any other. To copy a key
function, after entering the Learning Mode, and pressing the desired key
to be copied to, simply press the device key from which you wish to copy,
having rst pressed its Device Selector key if it resides on another “page.”
The status LED will turn green; press the Device Selector key again to exit
Learning Mode.
Example: Copy the Pause command from the CD page to the AMP [ ]
button:
• On the HTR 3, simultaneously press-and-hold [AMP] and [RES]; the Learn
LED turns steady green.
• Press Pause [ ] ; the Learn LED turns amber.
• Press [CD]; press Pause [ ] ; the Learn LED turns green.
• Press [AMP] again to exit the learning mode.
NOTE
The copy and punch-through functions are similar. However, if you
copy a command and then subsequently delete, or over-write the
original (source-key) command , the copied-to key’s command remains
unchanged. If you punch-through to a command and then delete or
over-write the original key, the punched-through functions also change
accordingly.
MACRO COMMANDS
A “macro” command is a series of two or more remote codes issued
automatically from a single keypress. You might use a macro to automate
a simple command sequence, such as, “Turn on the DVD player and then
press ‘play.’” Or you might compose an elaborate macro to power up
an entire system, select a source, choose a Listening Mode, and begin
playback—again, all from a single keypress. The HTR 3 can store one macro
on each of its function keys (these exclude the Device Selector keys).
NOTE
Macros are independent of the currently selected device.
RECORDING MACROS
To record a macro, simultaneously press-and-hold for 3 seconds both the
[MACRO] key and the HTR 3 function key to which you wish to assign the
macro, until the status LED turns green. The macro button will also light up.
Press the sequence of function keys to be recorded into the macro, being
sure to rst press the requisite Device Selector key for each function (you
may switch devices while recording the macro as many times as necessary),
allowing you to create macro containing commands from more than one
Device Selector “page.”
When you have nished entering the desired command sequence,
press [MACRO] againto store the macro; the Learn LED and [MACRO] key
illumination will turn o.
NOTE
Each macro can store a maximum of 64 command steps. If you exceed
this number, the macro will be stored automatically after the 64th
command is added.
OPERATION
USING THE HTR 3 REMOTE CONTROL
36
ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA РУССКИЙ
Example: Record a Macro to the [0] key to Turn on the T 755, Select “Input
1” (Source 1), and Commence Playback of connected Source 1 device (as in
DVD player):
• On the HTR 3, simultaneously press-and-hold [MACRO] and [0] (numeric
zero); the Learn LED turns steady green.
• Press [AMP]; press [ON]; press [1] (“Input or Source 1”); press [DVD]; press
[ ] (Play) - the Learn LED blinks as each step is added.
• Press [MACRO] again to exit the macro-record mode.
To clear a macro, perform the above steps without entering any functions.
EXECUTING MACROS
To execute a macro, press and release [MACRO]; its key illumination lights
for 5 seconds. While it remains lit, press an HTR 3 key to which a macro has
previously been stored.
The corresponding macro will run; as each step executes, its “parent” Device
Selector’s key ashes lights briey; when execution is nished, the [MACRO]
key illumination goes out. Pressing any other HTR 3 key while a macro is
executing will abort the macro. Remember that you must hold the HTR 3 so
that its infrared emitter can activate the target components.
NOTE
When a macro executes, a 1 second delay is automatically inserted
between its commands. If you need more than a 1 second delay between
particular commands—for example, to permit a component to power
up completely—you can record “empty” steps into the macro by
changing Device Selector “pages” without entering actual command
functions.
BUTTON ILLUMINATION TIMEOUT
The HTR 3’s key-illumination can be set to remain lit for 0-9 seconds. The
default value is 2 seconds. To set the illumination timeout, simultaneously
press-and-hold for 3 seconds both the HTR 3’s [DISP] and the [0-9] key, with
the digit corresponding to the desired timeout duration; the Learn LED will
ash twice to conrm the new setting. When set to zero, the illumination
will not turn on at all.
NOTE
Key illumination is the biggest drain on the HTR 3’s batteries. A short
key-illumination timeout will extend battery life appreciably; turning it
o altogether (set it to 0 seconds) will lengthen it still further.
FACTORY RESET
The HTR 3 can be reset to its factory state, deleting all learned commands,
copied and punched-through keys, macros, and other setup information,
reverting all keys to their pre-programmed library commands.
To perform a factory reset simultaneously press-and-hold for 10 seconds
the HTR 3’s [ON] and [RTN] keys; the Learn LED will start to ash green.
Release [ON] and [RTN] before the second ash is complete; the Learn LED
will turn red, indicating the remote has been reset.
NOTE
You must release [ON] and [RTN] before the second ash goes out,
otherwise the unit will not reset; should this occur, repeat the full
procedure.
DELETE MODE
The HTR 3 can store learned, copied, and “default library” commands on any
single key (The default library commands are the pre-programmed NAD
codes, such as the native T 755 commands on the [AMP] “page.”).
You can delete commands by layers back “down” to the default library
command on any key, removing learned commands, punched-through
functions, and copied keys.
NOTE
The default library commands cannot be deleted, so you need not worry
that using Delete Mode might cause irreparable changes.
To enter Delete Mode, simultaneously press-and-hold for 3 seconds both
the desired key’s Device Selector key and the [RTN] key, until the Learn LED
turns green. Press the function key whose command you wish to delete;
the Learn LED ashes; the number of times indicates which type of function
has become active - see the table below. Press the active Device Selector
key again to exit Delete Mode.
NOTE
You may delete multiple function-key commands on the same Device
Selector “page,” but to delete from more than one Device Selector page
you must exit Delete Mode and then re-enter it on the required page.

LOADING CODE-LIBRARIES
The HTR 3 can store a dierent library of default NAD codes for each of its
Device Selector “pages.” If the original default library does not control your
NAD CD player, tape deck, DVD player, or other component, follow the
procedure below to change the code-library.
Begin by ensuring that the component you wish the HTR 3 to control is
plugged in and powered-up (“on,” not merely in standby). To enter the
HTR 3s Library Mode, simultaneously press-and-hold for 3 seconds both the
desired Device Selector key and the [AVPS] key, until the Learn LED turns
green.
While keeping the HTR 3 pointed toward the component, enter the rst
appropriate three-digit code-library number from the table below. Press
[OFF]. If the component turns o, press [ENTER] to accept that code-library
number and exit the Library Mode. If the component does not turn o,
enter the next three-digit code-library number from the table.
When you enter the correct number the component will turn o; press
[ENTER] to accept that code library number and exit the Library Mode.

SEARCH MODE
If none of the codes from the table, when entered, turns on the
component, and if you are quite sure you have followed the above
procedure completely and carefully, you may want to try the “search”
method as follows:
Enter Library Mode by simultaneously pressing-and-holding for 3 seconds
both the desired Device Selector key and the [AVPS] key, until the Learn LED
turns green. Now press-and-hold the HTR 3’s [ ] or [ ]) key; the remote will
step through all the available codes at a rate of approximately 1 per second.
When the component turns o, immediately release the cursor key; press
[ENTER] to accept that code-library and exit the Library Mode. Try a few
commands; should you prove to have stepped past the needed code-
library, re-enter the Library Mode and use the cursor key to step back to it.
NOTE
It is possible that search mode will nd code-libraries that operate, at
least partially, some other brand (non-NAD) components. You may
certainly exploit such capabilities as you nd them. However, since we
can only ensure the completeness or accuracy of NAD code-libraries, we
cannot support the HTR 3’s operation with other-brand components.
CHECKING CODE-LIBRARY NUMBER
You can check the current code-library on any Device Selector key as
follows. Enter Library Mode by simultaneously pressing-and-holding for
3 seconds both the desired component’s Device Selector key and the
[AVPS] key, until the Learn LED turns green. Press the [DISP] key; the HTR 3
indicates the current code-library by ashing its [CUSTOM], [VCR], and
[MACRO] keys.
For example, to indicate code-library #501, the HTR 3 will ash [CUSTOM] 5
times, pause, and then ash [MACRO] once. You might wish to make a note
of your components’ code-library numbers.

SLEEP MODE
The Sleep Mode timer will switch the T 755 to Standby mode automatically
after a preset number of minutes. Pressing the HTR 3’s SLEEP button once
will display the setting of the sleep time increment. Pressing the HTR 3’s
SLEEP button a second time within a 3-second period will change the
sleep time increment in 15-minute intervals, after which time the T 755 will
automatically switch into Standby mode.
To adjust the sleep delay, press the HTR 3’s SLEEP button twice; rst to
display the sleep time increment, and a second time to change the
sleep time increment. The sleep time increment and a “SLEEP” icon will
continuously display on the T 755’s front panel Vacuum Fluorescent Display
(VFD). Each consecutive press increases the sleep time in 15-minute
increments from 15 to 90 minutes. To cancel the sleep mode, continue
pressing the HTR 3’s SLEEP button until “SLEEP OFF” displays on the VFD.
Switching the T 755 to standby from either the HTR 3’s OFF or the T 755’s
POWER button will also cancel the sleep mode
USING THE ZR 4 REMOTE CONTROL
The ZR 4 remote control is a discrete compact remote for controlling the
T 755 from various rooms other than the main room. The ZR 4 remote
allows full separate control of the source selection irrespective to the main
room. This means the zone input may be completely dierent, audio and
video, from the main input and thus corresponding volume levels as well.
If one wishes to enjoy the same source, as the main room the ZR 4 remote
has a [LOCAL] button to allow simultaneous listening, but with full separate
volume levels.
To mute the Zone Volume level, press [MUTE] on the ZR 4. If the “Zone Controls”
OSD menu is ON, the Zone “Volume” level section will display “Mute”.
The T 755’s front orescent display will show activity of the zone control
so that main room occupants are aware of the zone remote activity.
Furthermore if there is no main room activity, only the zone indicator will
be active in the T 755’s uorescent display.
NOTE
The ZR 4 remote control will only control Zone 2 applications. The HTR 3’s
“CUSTOM” device is also defaulted to Zone 2 remote control codes.
