(For details, refer to page 17.)
Description of Each Sound Field Program
The following list gives brief descriptions of the sound fields produced by each of the DSP programs. Keep in mind that most of these are precise digital recreations of actual acoustic environments. The data for them was recorded at the locations described using sophisticated sound field measurement equipment. Note: The channel level balance between the left rear effect speaker and the right rear effect speaker may vary depending on the sound field you are listening to. This is due to the fact that most of these sound field recreations are actual acoustic environments.
PROGRAM PRO LOGIC FEATURE This program is effective for playback of sources encoded with Dolby Surround. The employment of the digital signal processing system reduces crosstalk and transfers the sound source more smoothly and precisely, compared to conventional types. A stable movie sound field is recreated. This program is effective for playback of sources encoded with Dolby Surround. Enhancing the Normal Dolby Pro Logic, the DSP technology simulates the multi-surround speaker systems of a 35 mm film theater, thus widening the surround-sound field with greater presence. This program is effective for playback of sources encoded with Dolby Surround. The Yamaha DSP technology is ideally combined with the Dolby Pro Logic to present you the incredible listening experience of the 70 mm movie theater. This program is ideal for precisely reproducing the sound design of the newest movies. The sound field is made according to the design of the latest movie theaters, so the reverberations of the sound field itself are restrained as much as possible. The three-dimensional feeling of the sound field is emphasized and dialog is precisely oriented on the screen. You can enjoy watching sciencefiction, action, and adventure movies with this program. This program is suitable for dramas, variety or music programs, etc. Much surround effect can be gained for stereo sources. This program is furnished with a tight sound field in which the sound will not spread excessively on the front side, but the rear surround produces a dynamic sound expansion. This program is most suitable for sports programs encoded with Dolby Surround This program gives you long delays between direct sounds and effect sounds, and the extraordinarily spacious feel of a large stadium. This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically. This is a small, cosy jazz club with a low ceiling. The sound is very close and intimate. This program recreates the acoustic environment of a modern church with a high pointed dome and columns along the sides. This interior produces very few primary reflections. In this program, the center seems deep behind the front speaker pair, creating an expansive, large hall ambience.

Dolby Surround AC-3

Dolby Surround AC-3 is the next generation of multichannel consumer audio. It uses a low bit-rate audio encoding scheme, creating a single composite data stream that contains five high-quality full-range channels, plus a sixth low frequency effect channel (called 5.1). This unit is equipped with 5 CH DISCRT terminals for Dolby Surround AC-3. To listen to a 5 CH DISCRT SOURCE: Press the LD/TV button so that 5 CH DISCRT appears on the display. To cancel it, press the switch again.
When you switch to 5 CH DISCRT mode, the Digital Sound Field processor features of this unit are no longer available. The CENTER MODE switch, DELAY TIME switch and EFFECT switch also no longer work. Signals connected to the 5CH DISCRT INPUT are not output to the tape decks or video recorders. To record the signals from an LD player, you must connect the player to the LD/TV terminals.

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.

Whats 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.

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.

AC-3 DIGITAL OPTICAL/COAXIAL terminals

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.

A3. DYNAMIC RANGE

Choices: MAX/STANDARD Preset position: 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.) 16 MAX:
