Therefore, the audio amplifier or receiver must have “discrete” input terminals to receive the signals from this unit. If your amplifier or receiver can input 5-channel discrete signals only, see page 12. Digital Sound Field Processing This unit incorporates a sophisticated digital sound field processor. The processor allows you to electronically expand and change the shape of the audio sound field from audio and video sources, creating a theater-like experience in your listening room. Dolby Digital (AC-3) The built-in Dolby Digital (AC-3) Decoder leads you into a totally new sound experiences. English This unit is a sophisticated digital sound processor designed specifically for decoding the Dolby Digital (AC-3). This unit consists of a Dolby Digital (AC-3) Decoder, Yamaha Digital Sound Field Processor and other original Yamaha functions developed using the newest technology to reproduce sources encoded with the Dolby Digital (AC-3) precisely as movie sound creators intended. This unit will lead listeners into a totally new sound experience. Dolby Digital (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 Digital (AC-3) is a digital surround sound system that provides completely independent multi-channel audio to consumers. In multi-channel form, Dolby Digital (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 Digital (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. 3  Laser Disc is a home audio format that could benefit from Dolby Digital (AC-3). In the near future, Dolby Digital (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 Dolby Digital (AC-3) encoded video software.

The following original functions make the surround-sound effect of Dolby Digital (AC-3) become the most suitable for your audio system and the listening conditions. Dolby Digital (AC-3) + DSP (CINEMA DSP) Dolby Digital (AC-3) shows its full ability in a large movie theater, because movie sounds are originally designed to be reproduced in a large movie theater using many speakers. It is difficult to create a sound environment similar to that of a movie theater in your listening room, because the room size, materials of inside walls, the number of speakers, etc. of your listening room is much different from those of a movie theater. Yamaha DSP technology made it possible to present you with nearly the same sound experience as that of a large movie theater in your listening room by compensating for lack of presence and dynamics in your listening room with its original digital sound fields combined with Dolby Digital (AC-3) decoded sound field. CINEMA DSP ● ● ● 4 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. The YAMAHA “CINEMA DSP” logo indicates those programs are created by the combination of Dolby Surround and YAMAHA DSP technology.  Dolby Digital (AC-3) + 3 Digital Sound Fields Digital sound fields are created on the independent left and right surround sides of the Dolby Digital (AC-3) decoded sound field respectively. They create a wide acoustic environment and emphasize surround-effect in the room, letting you feel much presence as if you are watching a movie in a popular Dolby Stereo Digital theater. Digital sound fields are created on the presence side and the independent left and right surround sides of the Dolby Digital (AC3) decoded sound field respectively. They create a wide acoustic environment and much surround effect in the room without losing high channel separation. With wide dynamic range of Dolby Digital (AC-3) sound, this sound field combination lets you feel as if you are watching a movie in the newest Dolby Stereo Digital theater. This will be the most ideal home theater sound at the present time. “ This combination is available on the sound field program DIGITAL ENHANCED”. English Dolby Digital (AC-3) + 2 Digital Sound Fields This combination is available on the sound field program “DIGITAL MOVIE THEATER”. 5  CONTROLS & THEIR FUNCTIONS FRONT PANEL 1 2 NATURAL SOUND DIGITAL PROCESSOR DDP–2 3 4 5 CINEMA DSP DIGITAL ENHANCED DIGITAL MOVIE THEATER TEST TV/DBS DVD/LD POWER TV/DBS DVD/LD PCM AC 3 DIGITAL DSP PRO LOGIC SET MENU PARAMETER 6 7 dB ms 1 POWER Switch Turns this unit on and off. 2 Display Panel See page 7. 6 8 3 Remote Control Sensor Receives signals from the remote control unit provided for a Yamaha receiver or amplifier.

When both the Dolby Digital (AC-3) Decoder and the digital sound field processor are on, both indicators light up. 3 Multi-informatiom Display Shows the currently selected program, or information for several adjustments or setting changes made on this unit. 7  SPEAKER SETUP Setting Up Your Speaker System Use of the Center Dialog Speaker Is Recommended This unit has been designed to provide the best sound field quality with a five-speaker system setup, using one pair of main speakers for main and front effect sound reproduction, one pair of surround speakers for rear effect and surround sounds and one center speaker for dialog. We therefore recommend that you use a five-speaker setup. A four-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. When playing back a source with the Dolby Digital (AC-3) decoded, dialog etc. are output from the center channel. Therefore, if you want to maximize the performance of your Audio/Video home theater system, it is recommended that you use a center channel speaker. If for some reason it is not practical to use a center speaker, it is possible to enjoy movie viewing without it. Best results, however, are obtained with the full system. Use of a Subwoofer Expands Your Sound Field The use of a subwoofer is effective not only for reinforcing bass frequencies from any or all channels, but also for reproducing the LFE (low frequency effect) sound with high fidelity when playing back a source with the Dolby Digital (AC-3) decoded. You may wish to choose the convenience of a Yamaha Active Servo Processing Subwoofer System, which has its own built-in power amplifier. 8  English Speaker System Configurations Five-speaker system Main L Surround L Center Main R Surround R Set the center channel mode (1. CENTER SPEAKER) to the NRML or WIDE position. (See page 14.) A simple system without a center speaker Main L Surround L Main R Surround R Set the center channel mode (1. CENTER SPEAKER) to the PHNTM position. (See page 14.) 9  Speakers and Speaker Placement Your five-speaker system will require two speaker pairs: the MAIN SPEAKERS (your normal stereo speakers) and the SURROUND SPEAKERS, plus the CENTER SPEAKER. You may also be using a SUBWOOFER. The MAIN SPEAKERS should be high performance models and have enough power handling capacity to accept the maximum output of your audio system. Other speakers 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 for the CENTER SPEAKER and the SURROUND SPEAKERS. Place the MAIN SPEAKERS in the normal position. Place the SURROUND SPEAKERS behind your listening position. They should be nearly six feet up from the floor. Place the CENTER SPEAKER precisely between the two MAIN SPEAKERS. (To avoid interference, keep the speaker above or below the television monitor, or use a magnetically shielded speaker.) If using a SUBWOOFER, such as a Yamaha Active Servo Subwoofer System, the position of the speaker is not so critical because low bass tones are not highly directional. 10 Main speaker Subwoofer Surround speaker Center speaker  CONNECTIONS English Before you start making connections make sure all related electronic components are turned OFF.

Make sure that you have the left (L) and right (R) channels correctly connected. That means that jacks marked “L” on this unit must be connected to jacks marked “L” on the other unit. Likewise with the “R” jacks. This is easy if you remember to always use the red plug for the “R” jacks and the white plug for the “L” jacks. Use an amplifier or receiver equipped with discrete audio signal input jacks. Connect the 6CH DISCRETE OUTPUT jacks of this unit to the discrete audio input jacks of the amplifier or receiver so that each channel output is correctly connected to the corresponding input, that is “MAIN” to “MAIN”, “CENTER” to “CENTER”, “SURROUND” to “SURROUND” and “SUBWOOFER” to “SUBWOOFER”. If you use an amplifier or receiver (the Yamaha model RX-V2090 etc.) which has only 5-channel discrete input jacks without a SUBWOOFER input jack, no connection can be made from the SUBWOOFER output jack of this unit to the amplifier (or receiver). In this case, select the MAIN position on the function “4. LFE/BASS OUT”. (See page 15.) 12 CONNECTING WITH AN LD (DVD) PLAYER, TV/SATELLITE TUNER, ETC. Connect an LD player, DVD player, TV/Satellite tuner etc. which outputs digital audio signals encoded with the Dolby Digital (AC-3) to this unit. Two audio/video units can be connected to this unit. Connect an audio/video unit (LD player, DVD player, etc.) to the DVD/LD COAXIAL or OPTICAL digital signal input jack of this unit. In the same way, connect another unit (TV/Satellite tuner, etc.) to the TV/DBS COAXIAL or OPTICAL digital signal input jack of this unit. To make a connection between optical digital audio signal jacks, remove the cover from each jack, and then connect them by using a commercially available optical fiber cable that conforms to EIAJ standards. Other cables might not function correctly. Even if you connect an audio/video unit to the OPTICAL (or COAXIAL) jack of this unit, you must keep the unit connected with analog audio signal input jacks of the amplifier (or receiver), because the 6 channel discrete signals cannot be recorded by a tape deck or VCR connected to the amplifier (or receiver). NOTE: Be sure to attach the covers when the OPTICAL jacks are not being used, in order to protect the jacks from dust. NOTE: All digital audio signal input jacks are applicable to the sampling frequency of 32 kHz, 44.1 kHz and 48 kHz.  DVD player If your LD player has AC-3 RF signal output jack and no digital signal output jack for AC-3 discrete audio signals, connect the AC3 RF signal output jack to this unit’s OPTICAL (or COAXIAL) digital signal input jack by using an RF demodulator (separate purchase). First, connect the AC-3 RF signal output jack of the LD player to the AC-3 RF signal input jack of the RF demodulator. Next, connect the optical (or coaxial) digital signal output jack of the RF demodulator to the OPTICAL (or COAXIAL) digital signal input jack of this unit. This connection is necessary for inputting audio signals encoded with the Dolby Digital (AC-3) on the LD player to this unit.

LFE/BASS OUT See pages 14 to 16 for details. (Once you have selected proper modes, you do not have to make a setting change until any alteration is made in your speaker system.) 5. LFE LEVEL (Adjusting the output level at the LFE (low frequency effect) channel) Control range: –20 dB to 0 dB (in 1 dB step) Preset value: 0 dB Adjusts the output level at the LFE (low frequency effect) channel. If the LFE signals are mixed with signals at other channels to output them from the same speakers, the ratio of LFE signal level to the level of other signals are adjusted. (See page 3 for details about the LFE channel.) 6. CENTER DELAY (Adjusting the delay of center sounds (dialog etc.)) 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 etc. is generated. This is for making sounds from the left main, center and right main speakers reach your listening position at the same time by delaying the sound from the center speaker if the distance from the center speaker to your listening position is shorter than the distance from the left or right main speaker to your listening position. 7. SURROUND DELAY (Adjusting the delay of rear surround sounds) Control range: 0 ms to 15 ms (in 1 ms step) Preset value: 15 ms Adjusts the delay between the main sounds (at the main channels) and surround sounds. (at the rear channel). The larger the value, the later the surround sounds is generated. 20  Choices: MAX/STD/MIN 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. Dolby Digital (AC-3) technology can bring the original sound track into a home audio format with this wide dynamic range unchanged. In this position, a source encoded with the Dolby Digital (AC-3) 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. STD (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. Dolby Digital (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, a source encoded with the Dolby Digital (AC-3) is reproduced in the “compressed” dynamic range of the source suitable for low level listening. MIN: In this position, dynamic range is more reduced than in the STD position. Selecting this position will be effective when you must listen to a source in extremely low level. English 8. DYNAMIC RANGE (Adjusting dynamic range) 9. OUTPUT TRIM (Adjusting the whole level of signals output from this unit) Control range: –9 dB to 9 dB (in 1 dB step) Preset value: 0 dB Adjusts the whole level of signals output from the 6CH DISCRETE OUTPUT jacks on the rear of this unit. Memory back up Setting changes and adjustments you made the last time will remain memorized even if the power of this unit is switched off or the power cord is disconnected. However, if the power is not supplied for more than about two weeks, they will be automatically changed back to the original settings. 21  OPERATIONS To enjoy listening to a source with the Dolby Digital (AC-3) decoded 1.

The realization of a highly efficient decoding process improves crosstalk and channel separation and makes sound positioning smoother and more precise. DIGITAL ENHANCED ( DIGITAL DSP DSP ) This program is ideal for precisely reproducing the sound design of the newest Dolby Digital multi-track films. The sound field is made to be similar to that of the newest 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 SciFi, adventure movies, etc. with much presence. ) This program ideally simulates the multisurround speaker systems of the Dolby Stereo Digital theater. The Dolby Digital (AC3) decoding and the digital sound field processing is precisely performed without altering the originally designed sound orientation. The surround effects produced by this sound field folds the viewer naturally from the rear to the left and right and toward the screen. 24 DIGITAL NOTES • The Dolby Digital (AC-3) Decoder is designed to be used with program material (mainly movie soundtracks) encoded with the Dolby Digital (AC-3). • The consequence of signal processing depends on the mode of Dolby Digital (AC-3) encoded on the signals of source. For example, if the input signals of source encoded with the Dolby Digital (AC-3) are in 2-channels only, the decoded signals are output from this unit in 2-channels, no matter what program is selected.  TROUBLESHOOTING No sound from the center speaker.
