The Digital Sound Field Processor (DSP) built into this unit takes advantage of Yamaha’s undisputed leadership in the field of digital audio processing to bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a totally new listening environment. In addition, you will get incredible realism from sources encoded with Dolby Surround using the built-in Dolby Pro Logic Surround Decoder. Please read this operation manual carefully and store it in a safe place for later reference. Digital Sound Field Processing What is it that makes live music so good? Today’s advanced sound reproduction technology enables you to get extremely close to the sound of a live performance, but chances are you’ll still notice something missing: the acoustic environment of the live concert hall. Extensive research into the exact nature of the sonic reflections that create the ambience of a large hall has made it possible for Yamaha engineers to bring you this same sound in your own listening room, so you’ll feel all the sound of a live concert. Furthermore, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of actual music venues to allow you to accurately recreate live performance environments in your own home. Dolby Pro Logic Surround This unit employs a Dolby Pro Logic Surround decoder similar to professional Dolby Stereo decoders used in many movie theaters. By using the Dolby Pro Logic Surround decoder, you can experience the dramatic realism and impact of Dolby Stereo theater sound in your own home. Dolby Pro Logic employs a four-channel-five-speaker system. The Pro Logic Surround system divides the input signal into four levels: the left and right main channels, the center channel (used for dialog), and the rear surround sound channel (used for sound effects, background noise, and other ambient noises). The center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from the action on the screen while experiencing good stereo imaging. Dolby Surround is encoded on many sound tracks of prerecorded video tapes, laserdiscs, and some TV/cable broadcasts. When you play a source encoded with Dolby Surround on this unit, the Dolby Pro Logic Surround decoder decodes the signal and supplies the surround-sound effects to you. 6 In addition, this unit features a built-in automatic input balance control. This always assures you of the best performance without manual adjustment. Manufactured under license from Dolby Laboratories Licensing Corporation. “Dolby”, the double-D symbol and “Pro Logic” are trademarks of Dolby Laboratories Licensing Corporation.  English SPEAKER SETUP SPEAKERS TO BE USED This unit is designed to provide the best sound-field quality with a 5-speaker configuration. The most effective speakers to use with this unit are main speakers, rear speakers and a center speaker. You can use only one rear speaker instead of using two rear speakers, and omit the center speaker. (Refer to the “SPEAKER CONFIGURATION” shown below.) The main speakers are used for the main source sound plus the effect sounds. They will probably be the speakers from your present stereo system. The rear speakers are used for the effect and surround sounds, and the center speaker is for the center sounds (dialog etc.) within the programs encoded with Dolby Surround. The center speaker needs to be equal in power to the main speakers although the rear speakers should not be equal. However, all the speakers should have high enough power handling to accept the maximum output of this unit. SPEAKER CONFIGURATION 5-Speaker Configuration 4-Speaker Configuration (without the center speaker) This configuration is the most effective and recommended one. In this configuration, the center speaker is necessary as well as the rear speakers. If the program PRO LOGIC or 3 STEREO is selected, conversations will be output from the center speaker and the ambience will be excellent. • Set the center channel mode to the “NORM” or “WIDE” position. (For details, refer to page 16.) The center speaker is not used in this configuration. If the program PRO LOGIC is selected, the center sound will be output from the left and the right main speakers. The program 3 STEREO has no effect in this configuration. However, the sound effect of other programs can be almost the same as that of the 5-speaker configuration. • Be sure to set the center channel mode to the “PHANTOM” position. (For details, refer to page 16.) Main L Center Main R Main L Rear R Rear L (Two rear speakers) Center Main R Rear (One rear speaker) Main L Main R Rear L Rear R (Two rear speakers) Main R Main L Rear (One rear speaker) Note As this unit is equipped with a monaural amplifier for the rear channel, sounds output from the rear speakers are in monaual. So, you may use only one rear speaker instead of using two rear speakers. However, the use of two rear speakers is recommended when there is more than one listener in the listening room. When using one rear speaker, place it right behind your listening position. SPEAKER PLACEMENT The recommended speaker configuration, the 5-speaker configuration, will require two speaker pairs: main speakers (your normal stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following. Main: In normal position. (The position of your present stereo speaker system.) Rear: Behind your listening position, facing slightly inward. Nearly 1.8m (approx. 6 feet) up from the floor. Center: Precisely between the main speakers. (To avoid interference with TV sets, use a magnetically shielded speaker.)

The processor allows you to electronically expand and change the shape of the audio sound field from both audio and video sources, creating a theater-like experience in your listening room. In addition, this unit incorporates a Dolby Pro Logic Surround decoder for multi-channel sound reproduction of sources encoded with Dolby Surround. The operation of the Dolby Pro Logic Surround decoder can be controlled by selecting a corresponding DSP program. You can create an excellent audio sound field by selecting a suitable sound field program (this will, of course, depend on what you will be listening to), and adding desired adjustments. Brief Overview of Digital Sound Field Programs The following list gives you a brief description 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 these sound fields was recorded at actual locations using sophisticated sound field measurement equipment. Note The channel level balance between the left and right rear effect speakers may vary depending on the sound field you are listening in. This is due to the fact that most of these sound field recreations are actual acoustic environments. PROGRAM PRO LOGIC 24 FEATURE This program is used for playback of sources encoded with Dolby Surround. Dialog is oriented on the screen and effect sounds are effectively located on the left front, right front and rear surround sides respectively as the movie sound creater designed. 3 STEREO This program is effective not only for playback of sources encoded with Dolby Surround, but also for sources not encoded with Dolby Surround or TV programs encoded with 2-channel stereo sound. With this program, 2-channel stereo sound is converted into 3-channels (left front, center and right front), so dialog is emphasized on the center position by the use of the center speaker. As no sound is output from the rear speakers, this program is also effective in a simple Audio/Video system without rear speakers. HALL In this program, the center will appear to be deep behind the main speakers, creating an expansive large hall ambience. Orchestra and opera music are suited for this sound field. ROCK This program is ideally suited for rock music. You will experience a very dynamic or lively sound field.  English Playing a source with an effect of the digital sound field processor (DSP) NATURAL SOUND AV RECEIVER VOLUME PHONO DISC SKIP l6 TAPE/MD MONITOR VCR 20 VIDEO l2 28 8 SKIP STANDBY/ON A/B/C/D/E 1 2 3 4 5 6 7 PHONO CD CD 4 40 TUNER — PRESET 2 60 + A/B/C/D/E TUNER 8 0 –dB BASS 0 l PHONES TREBLE 0 l l l 2 2 3 3 4 4 5 5 2 BALANCE 0 l l 2 3 3 4 4 5 5 2 FM/AM DOWN TUNING UP EFFECT CENTER MODE CENTER LEVEL REAR LEVEL DIR A DIR B 3 3 4 MEMORY EDIT TUNING MODE PROGRAM 4 L5 5 R 0 MAN'L/AUTO FM l0 0 l0 VIDEO AUTO/MAN'L MONO REC/PAUSE A/B 2 2 PRO LOGIC 2 Select the desired program that is suitable for the source.
