FCC INFORMATION (for US customers only)

YAMAHA and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion – and, most importantly, without affecting your sensitive hearing.

Since hearing damage from loud sounds is often undetectable until it is too late, YAMAHA and the Electronic Industries Association’s Consumer Electronics Group recommend you to avoid prolonged exposure from excessive volume levels.

We Want You Listening For A Lifetime (for US customers only)

Caution: Read this before operating your unit

1 To assure the finest performance, please read this

manual carefully. Keep it in a safe place for future reference.

2 Install this unit in a cool, dry, clean place – away from

windows, heat sources, sources of excessive vibration, dust, moisture and cold. Avoid sources of humming (transformers, motors). To prevent fire or electrical shock, do not expose the unit to rain and water.

3 Do not operate the unit upside-down. It may overheat,

possibly causing damage.

4 Never open the cabinet. If something drops into the set,

contact your dealer.

5 Do not use force on switches, controls or connection

wires. When moving the unit, first disconnect the power plug and the wires connected to other equipment. Never pull the wires themselves.

6 Do not attempt to clean the unit with chemical solvents;

this might damage the finish. Use a clean, dry cloth.

7 To prevent lightning damage, pull out the power cord

and remove the antenna cable during an electrical storm.

8 When not planning to use this unit for long periods

of time (ie., vacation, etc.), disconnect the AC power plug from the wall outlet.

9 Be sure to read the “TROUBLESHOOTING” section

regarding common operating errors before concluding that the unit is faulty.

10 AC outlet

Do not connect audio equipment to the AC outlet on the rear panel if that equipment requires more power than the outlet is rated to provide.

The apparatus is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the apparatus itself is turned off.

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.

CONNECTIONS
