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.

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 owners 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.)

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 tracks 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 tracks 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
