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.

• 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.

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

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.

Main: In normal position. (The position of your present

stereo speaker system.)

Surround: Behind your listening position, facing slightly

inward. Nearly six feet (approx. 1.8 m) up from the

floor.

Center: Precisely between the main speakers. (To avoid

interference with TV sets, use a magnetically

shielded speaker.)

Set the center channel mode (C2. CENTER SP.) to the SML or

LRG position. (See page 10.)

Set the center channel mode (C2. CENTER SP.) to the

PHANTOM position. (See page 10.)

Note

If you will add a subwoofer in your system that includes the RX-V2090, connect the subwoofer to the “LOW PASS” terminal of the

RX-V2090. In doing so, the overall adjustment of speaker output levels including the subwoofer can be done with the master

VOLUME control of the RX-V2090.

Note 1) If this unit is connected to the RX-V2090, no

connection is needed to this terminal. By the output

mode selections on function C2 to C5, low frequency

signals including signals from the LFE channel can

be output from the main L and R speakers. (See

page 10 for details.)

If the amplifier has a discrete subwoofer input

terminal, connect it with this unit’s SUBWOOFER

OUTPUT terminal.

Note 2) Do not connect a normal audio output terminal of a

laserdisc player etc. to this unit’s AC-3 RF terminal.

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

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

Preset value: 0 ms

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.

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.)

A4. HIGH LEVEL CUT SCALE

Control range: 0.0 to 1.0 (in 0.2 step)

Preset value: 1.0

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.

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.

Press once or more until “A”

appears on the left side of

the display.

Press once or more until the

title of function whose level

(or selection) you will change

appears on the display.

Change the level (or the selection).

* For changing the value,

pressing “+” increases

and “–” decreases the

value.

Pressing and holding

the button will change

the value continuously.

Repeat step 2 and 3 to make changes on other

functions in the same way.

Note

If there is no operation for about 5 seconds, the original

message will be restored on the display.

SYMPTOM

The unit fails to turn on when the

POWER switch is pressed.

No sound.

Sound “hums”.

Poor bass reproduction.

Sound output level to either or both

of the rear surround speakers is

lower than other speakers.

No sound from the center speaker.

No output of LFE sound.

Whole sound level is low, even

though the volume is increased on

the amplifier.

The difference of sound level

between a high level part and a low

level part is too great.

Noise from nearby TV or tuner.

CAUSE

Power cord is not plugged in or is not

completely inserted.

Incorrect input or output cord

connections.

Improper input mode selection.

Improper input mode selection on the

amplifier.

Incorrect cord connections.

The setting of LFE/BASS OUT is at the

SUBWOOFER position, though your

system does not include a subwoofer.

Output mode selection for each channel

(MAIN, CENTER or REAR) is improper.

Sound output level to either or both of

the rear surround speakers is

decreased.

The setting of CENTER SP. is at the

PHANTOM position.

The output level of LFE (LFE MIX LVL)

is adjusted to MUTE.

Output level (OUTPUT TRIM)

adjustment on this unit is low.

The setting of the DYNAMIC RANGE is

at the MAX position.

This unit is too close to the affected

equipment.

REMEDY

Firmly plug in the power cord.

Connect the cords properly. If the

problem persists, the cords may be

defective.

Select the proper input mode (RF, OPT

or COAX).

Select the “5-ch discrete AC-3 input”

mode on the amplifier.

Firmly connect the audio plugs. If the

problem persists, the cords may be

defective.

Select the MAIN position.

Make output mode selections suitable

for your speaker system.

Increase the level.

Select the SML or LRG position.
