REMOTE CONTROLLER
The TU6 is primarily designed for operation
utilising the supplied 29 button Universal
infra-red remote controller. Preparing the
controller for operation only requires removal
of the battery housing on the back of the
controller and installing the 2x AAA batteries
provided.
Control of the TU6 is achieved via 17 buttons
either coloured blue or labelled blue to the
right of the button.
Note: Press the blue button labelled ‘TU’ to
engage the TUNER code-set

The following is a list of the remote controller
buttons and description of their functions:
Also Refer FRONT PANEL DISPLAY &
CONTROLS below.
STANDBY (Top right button)
The power or stand-by control button is
located both on the remote control and front
panel. Depressing this control alternately
enables stand-by mode or normal operate
mode .When switching from stand-by to
normal operation the display on the front

panel will illuminate after approximately 2 - 3
seconds.
NOTE: The POWER indicator light located
above the front panel power button will
always be illuminated when the TU6 is
receiving power from an AC power outlet.
The stand-by mode will only operate if this
light is illuminated
BAND (Located on the white button
labelled RND)
The Band button is located both on the front
panel and remote controller. Depressing this
control alternately switches between AM and
FM bands
TUNE + UP (located on the white
CD next track button)
TUNE - DOWN (located on the
white CD previous track button)
Tuning control buttons are located on both
the remote control and front panel. These
controls allow for manual search of AM and
FM frequencies, up or down the band for
suitable stations or auto search up or down if
this option is selected (see AUTO TUNING
below)
AUTO TUNING (Located on the
white CD A=B button)
The auto tuning or scan button is located only
on the remote controller and is enabled or
disabled by repeated selection of this button.
When auto tuning is selected 'AUTO' is
illuminated on the front panel display. Auto
tuning operates with the tuning up / down
buttons enabling the tuner to scan for suitably
strong stations up or down the selected AM
or FM band. When a signal is sensed the
tuner will lock-on allowing the user to either
pre-set the station via a memory setting or
continue searching by repeated use of the

tune up / down buttons. This feature is
particularly useful when pre-setting memory
channels or for surfing the selected band.
DIRECT
STATION
PRESET
BUTTONS 1 – 10 10+ (White numbered
buttons)
The Channel Preset buttons are labelled 1 to
10 with an additional button marked 10+ and
are located on the remote controller only.
These buttons allow direct selection of preprogrammed station channel pre-sets and
are also used in the initial station pre-setting
procedure (see MEMORY section in
applicable manual). For selection of channels
1 through 10 simply point the remote towards
the tuner front panel and depress the channel
number required. For channels 11 through 20
depress the 10+ button then release it. Then
depress the number of the second digit of
your required selection i.e. if channel number
15 is required depress the 5 after depressing
and releasing the 10+ button at which time
the display will indicate 'CH15'.
Note: do not push both the 10+ and 5 buttons
together as no signal will be sent .
FRONT PANEL DISPLAY & CONTROLS
Whilst the TU6 is primarily designed for
operation utilising the supplied remote
controller, there are however some basic and
seldom used controls on the front panel - the
following is a list of the front panel controls
provided and description of their functions:
(Also Refer REMOTE CONTROLLER sections
above).
- STANDBY BUTTON
The power or standby control button is
located both on the remote control and front
panel. For a description of it's operation refer
4

to STANDBY BUTTON in the
CONTROLLER section above .

Tuned (if tuned to a station)
−− ( # of a memorised station pre-set )
Ch−
- MUTE OFF / MONO BUTTON
The Mute Off / Mono control button is not
replicated on the remote control. It is
designed to enable the TU6 to receive weak
signal strength stations. Operation of this
mode will defeat the muting circuitry and
produce a mono output signal. (The muting
circuitry employed in the TU6 is designed to
remove unwanted hiss and spurious noise ).
NOTE: At initial turn - on (i.e. for the first
time) the Mute Off / Mono function is
selected. To select stereo operation, push
the Mute Off / Mono button once at initial

installation. This set-up will not have to
repeated except if the TU6 mains supply is
interrupted for more than a week or so.
- BAND
The Band button is located both on the front
panel and remote controller. Depressing this
control alternately causes the TU6 to switch
between AM and FM bands
- MEMORY BUTTON
The Memory control button is not replicated
on the remote control however this control in
conjunction with the remote controller
enables pre-setting of up to 20 AM or FM
stations, directly accessible from the remote
control. The instructions for setting up pre-set
stations are as follows a) Select the band AM or FM you wish to
select a radio station from.
b) Select a station you wish to pre-set using
the tuning buttons on the remote control or
front panel in either manual or auto tuning
modes.
c) Decide which channel (pre-set) number to
assign to the station (We will use channel 11
for this example).
d) With the remote in one hand, push the
Memory button on the TU6 front panel at
which time the Memory light will illuminate.
e) Point the remote at the TU6 front panel
and depress the 10+ button then release it.
Then depress the number 1 button and
release it at which time the display will
indicate 'CH11' and the 'MEMORY' light will
extinguish - CH11 is now pre-set.
Note: do not push both the 10+ and 1 buttons
together as no signal will be sent .

f) To pre-set further channels repeat as
above.
NOTE: The Memory light will extinguish after
approximately 5 seconds if no pre-set
channel number request is received from the
remote control. If you have been too slow
setting the pre-set channel number simply
press the Memory button again and re-select
the channel number required.
- REMOTE SENSOR WINDOW
This window is located to the right of the front
panel indicator panel and houses the remote
sensor. Ensure this area is not covered in
any way as this may inhibit the remote
controls performance
REAR PANEL CONNECTIONS / LABELS
The following user connections and labels
are situated on the rear panel of the TU6 Please ensure all warnings are read, noted
and adhered to.
- SERIAL NUMBER LABEL
All Perreaux units are allocated a unique
serial number which are recorded at the
factory against build details. If you should
require information about your unit, providing
the serial number will help achieve a prompt
reply. Keep a copy of all your serial numbers
in a safe place. The ability to identify and
prove ownership can be very useful.
- MAINS/LINE VOLTAGE LABEL
The voltage label indicates the mains/line
voltage the unit will accept. Always check
this setting when first installing your TU6. A
variance of +/- 5% above or below that
voltage indicated is acceptable. Contact your
5

Perreaux dealer for any voltage adjustment
and updating of this label.

quality cables at your earliest convenience for
improved fidelity.

- Turn on the TU6, the control amplifier and
lastly the power amplifier (if applicable).

- FM ANTENNA SOCKET
This socket is for the connection of the FM
antenna provided. The antenna should be
extended and positioned for the best
reception however it should be noted that
superior performance will be achieved using
a professionally installed outdoor antenna.
NOTE: Outdoor antenna's can be dangerous
if incorrectly installed and through incorrect
earthing - we recommend using the services
of a registered contractor for outdoor antenna
installation.

- MAINS/LINE INPUT RECEPTACLE
This receptacle accepts the female end
of the mains power cord. For more
information
regarding
MAINS/LINE
VOLTAGE and connection see the
relevant sections.

- Depress the FM or AM Band button on the
remote controller to select the band required.

INSTALLATION
PROCEDURES

NOTE: If you have turned off the TU6 and
turn it on again, it will tune into the station
frequency to which it was tuned immediately
before turn-off.

- AM / GROUND ANTENNA SOCKETS
These sockets are for the connection of the
AM loop antenna provided. Again this
antenna should be positioned for the best
reception. A mounting clip is provided on the
rear panel to hold this antenna. It should be
noted that the inherent performance of AM
signal broadcasts is not of high fidelity and
can be noisy, hence the reason for the
popularity of FM broadcasts.
- LEFT / RIGHT OUTPUT SOCKETS
These are high quality gold plated RCA type
sockets for the connection of the TU6 to a
pre or integrated amplifiers TUNER input.
When connecting the TU6 to auxiliary
equipment terminate the interconnect cables
with a red plug for the right channel and
white, black or blue for the left channel.
These are the most commonly accepted
colour
coding
combinations
in
use
internationally to help maintain channel and
phase integrity i.e. left to left, right to right,
positive to positive, and negative to negative.
An initial set of interconnects is provided
however we recommend substituting higher

OPERATION

The Perreaux Tuner employs a quartz PLL
synthesiser for easy and accurate tuning.
Tuning frequency is visible on the digital
display, and you can tune in to the desired
station very accurately. With the units
memory circuit, you can pre-set memory
tuning, letting you recall a stored station
frequency instantly with a single tap of a
button.
One station can store one AM or one FM
station in its memory; a total of 20 AM or FM
stations can be stored.
The power source of the TU6's memory
circuit is a capacitor back-up type. The
electrical energy accumulated in the
capacitor while the unit was switched ON will
retain the frequencies stored in the memory
circuit for a minimum of seven (7) days.
Before commencing operation, check to
make sure all antenna preamplifier and
power connections are properly made.
- Set the volume control on the control
amplifier to a low position and selection
switch to the tuner position.

- Tune in to the desired station( See relevant
sections TUNING and AUTO TUNING.
- Raise the volume to the desired level and
enjoy listening

INSTALLATION AND OPERATION
PRECAUTIONS
Precautions which should be observed
during installation and operation are:
- Leave sufficient clearance between the top
of the TU6 and the bottom of
equipment
above if installed in a rack or stack.
- Always operate in a horizontal position.
- Install away from excessive heat and
moisture.
Do not allow the ambient
temperature around the TU6 to exceed 40º
Celsius (105º Fahrenheit.)
- Check the mains/line voltage stated on the
rear panel of your .TU6 Supply voltage must
be within +/- 5% of the stated voltage.
- Connect all your hi-fi equipment to the same
mains/line source to avoid possible earthing
problems.
- The protection fuses for the TU6 are
internal and not user serviceable.
6

- Always contact an approved PERREAUX
dealer if any changes are noted in
performance.
- Always ensure the volume control on your
control amplifier is set low before making any
connection alterations or when changing
input sources. The reason for this precaution
is to protect your loudspeakers against bursts
of very high powered signals from high level
sources such as a CD player or whilst tuning
the TU6 between stations when high level
spurious noise can be present. Situations can
arise when playing a low output cassette with
a fairly high volume control setting then
switching to CD or Tuner where a high level
of signal may be present at the source input
sockets. The resulting burst of high power
may damage your speakers or cause
damage in some power amplifiers.
- Make all connections logically and carefully, checking that you are maintaining
channel integrity.
- Install your Tuner close enough to your
control amplifier to avoid stretching or
extending your interconnect leads.
- Keep your interconnect cables and antenna
leads away from all mains / line cables and
speaker leads.

The TU6 will operate satisfactorily within a
voltage variation of up to +/- 5% of that
voltage at which the unit has been set.
If you require the voltage setting to be
altered, e.g. relocation to another area, city or
country, or extraordinarily high or low
voltages, contact your Perreaux dealer. This
modification can only be performed by
qualified service personnel.
NOTE : Always ensure this unit is
disconnected from the Mains/Line supply
before any covers are removed
Any modifications to the mains/line voltage
setting within your Perreaux product may only
be carried out by a approved Perreaux
service agent. Failure to recognise this
warning will void any warranty.
MAINS/LINE FUSE
The Perreaux TU6 is equipped with internal
mains/line fuses which are not user
serviceable. These fuses do not usually blow
without a reason. Any doubts about fuse
failure should be conveyed directly to your
Perreaux dealer.
NOTE: Always ensure your TU6 is
disconnected from the mains/line supply if
attempting to change the mains/line fuse.

MAINS/LINE VOLTAGE CHANGE
It is important that the TU6 be operated from
the correct mains/line voltage. This unit is
factory set for the voltage applicable to the
original country of destination. The correct
operating voltage is indicated by the voltage
label on the rear panel (see section MAINS
LINE VOLTAGE LABEL).
