PROFILE OF THIS UNIT
Thank you for purchasing the Yamaha DDP-1, a sophisticated
digital sound processor designed specifically for decoding
Dolby AC-3.
This unit consists of an AC-3 RF demodulator, an AC-3
decoder and other original Yamaha functions developed using
the newest technology to reproduce AC-3 encoded sources
precisely as movie sound creators intended. AC-3 will lead
listeners into a totally new sound experience.

This unit is equipped with “discrete” terminals for sending AC-3
multi-channel audio signals individually. The audio amplifier or
receiver must have “discrete” input terminals to receive the
signals from the DDP-1. The use of Yamaha RX-V2090, a
multi-channel audio/video receiver equipped with discrete input
terminals combined with this unit is an ideal choice for the
purpose of experiencing AC-3 sound, and this is the best
system we recommend.

What’s Dolby AC-3?
Dolby AC-3 is a new generation of multi-channel digital audio
technology, or the newest spatial sound processing format
developed for 35 mm film-movies by employing a new kind of
low bit-rate audio coding.
Dolby Surround AC-3 is a digital surround sound system that
provides completely independent multi-channel audio to
consumers.
In multi-channel form, Dolby Surround AC-3 provides five full
range channels in what is sometimes referred to as a “3/2”
configuration: three front channels (left, center and right), plus
two surround channels. A sixth bass-only effect channel is also
provided for output of LFE (low frequency effect), or low bass
effects that are independent of other channels. This channel is
counted as 0.1, thus giving rise to the term 5.1 channels in
total.
Compared to Dolby Pro Logic that is referred to a “3/1” system
(left front, center, right front and just one surround channel),
Dolby Surround AC-3 features two surround channels, called
stereo or split surrounds, each offering the same full range
fidelity as the three front channels.

Sound of wide dynamic range reproduced by the five full range
channels presents listeners much excitement that has never
been experienced before. Precise sound orientation by the
discrete digital sound processing expands realism that the
original movie possesses.
Laser Disc is a home audio format that could benefit from
Dolby AC-3. In the near future, Dolby AC-3 will also be applied
to DBS, CATV, DVD and HDTV. The ongoing release of Dolby
Stereo Digital theatrical films now underway will provide an
immediate source of AC-3 encoded video software.

Features of this unit
• Dynamic range (sound scale) of source can be
changed so that it will be suitable for the listening
conditions.

• Output of low bass from any channel can be
assigned to either the MAIN OUTPUT terminals or
SUBWOOFER OUTPUT terminal to maximize
system performance.

• Output of LFE can be assigned to either the MAIN
OUTPUT terminals or SUBWOOFER OUTPUT
terminal to maximize system performance.

• Test tone generator helps you adjust speaker level
balance.

• Center channel output can be sent to the main
speakers if you do not use a center channel
speaker.

• Three types of inputs (AC-3 RF, AC-3 Digital
Optical and Coaxial) are available for future use.

SPEAKER SYSTEM SETUP
As described on page 4, we recommend you to use this unit
connecting with the Yamaha RX-V2090. If you have already
set up a speaker system for the RX-V2090, you do not need to
prepare a new speaker system for this unit. Some functions on
this unit have been already preset to be suitable when this unit
is used with a speaker system for the RX-V2090. (Refer to
page 10 for details about those functions.)
This unit will provide the best performance with a five-speaker
system setup: one pair of main speakers for main sound
reproduction, one pair of surround speakers for effect and
surround sounds and one center speaker for dialog. A simple
speaker system excluding a center speaker will still provide
impressive ambience and effects, however, and may be a
good way to begin with this unit. You can always upgrade to
the five speaker system later.

* For the best performance of the RX-V2090, the system
needs one more pair of surround speakers at the front
position. (Refer to the owner’s manual of the RX-V2090 for
details.)
Main speakers should be high performance models and have
enough power handling capacity to accept the maximum
output of your system.
Surround speakers and a center speaker do not have to be
equal to the main speakers. For precise sound localization,
however, it is ideal to use high performance models that can
reproduce sounds in full range.
If for some reason it is not practical to use a center speaker,
you can enjoy AC-3 effect without it. Best results, however, are
obtained with the full system.

ADJUSTING DELAYS AND DYNAMIC RANGE
This unit provides you with the following functions to make the AC-3 sound field suitable for the conditions of your listening room.

A1. CENTER DELAY
A2. SURROUND DELAY
A3. DYNAMIC RANGE
A4. HIGH LEVEL CUT SCALE
A5. LOW LEVEL BOOST SCALE

Description of each function
A1. CENTER DELAY

A4. HIGH LEVEL CUT SCALE

Control range: 0 ms to 5 ms (in 1 ms step)
Preset value: 0 ms

Control range: 0.0 to 1.0 (in 0.2 step)
Preset value: 1.0

Adjusts the delay between the main sounds (at the main
channels) and dialog etc. (at the center channel).
The larger the value, the later the dialog is generated.

Adjusts the dynamic range of high level signals of source. The
larger the value, the range is more reduced. The smaller the
value, the range is more widened.
Note: This function is available only when the “STANDARD”
position is selected on the function A3.

A2. SURROUND DELAY
Control range: 0 ms to 15 ms (in 1 ms step)
Preset value: 5 ms
Adjusts the delay between the main sounds (at the main
channels) and the effect sounds (at the surround channels).
The larger the value, the later the effect sounds are generated.

A3. DYNAMIC RANGE
Choices: MAX/STANDARD
Preset position: MAX
MAX:

“Dynamic range” is the difference between the
maximum level and the minimum level of sounds.
Sounds on a movie originally designed for movie
theaters feature very wide dynamic range.
AC-3 technology can bring the original sound track
into a home audio format with this wide dynamic
range unchanged.
In this position, an AC-3 source is reproduced in the
original sound track’s wide dynamic range providing
you with powerful sounds like a movie theater.
Selecting this position will be more ideal if you can
listen to a source in a high output level in a room
specially soundproofed for audio/video enjoyment.
STANDARD:
Powerful sounds of extremely wide dynamic range
are not always suitable for home use. Depending
upon the condition of your listening environment, it
may not possible to increase the sound output level
as high as a movie theater, however, in a level
proper for listening to in your room, the low level
parts of source sound cannot be heard as well
because they will be lost among noises in your
environment.
AC-3 technology also makes it possible to reduce an
original sound track’s dynamic range for a home
audio format by “compressing” the data.
In this position, an AC-3 source is reproduced in the
“compressed” dynamic range of the source suitable
for low level listening.
If you desire, you can also adjust the dynamic range
on function A4 and A5 only when this position is
selected. (See the right side for details.)
16

A5. LOW LEVEL BOOST SCALE
Control range: 0.0 to 1.0 (in 0.2 step)
Preset value: 1.0
Adjusts the dynamic range of low level signals of source. The
larger the value, the range is more widened. The smaller the
value, the range is more reduced.
Note: This function is available only when the “STANDARD”
position is selected on the function A3.
