Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a wide range of listening environments –movie theater, concert hall, and so on. In addition, you 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 lets you 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 a variety of venues such as an actual concert hall and theater to allow you to accurately recreate one of several actual live performance environments, all 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 Surround movie 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 channels (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 the sound track of prerecorded video tapes, laser discs, 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 distributes the surround-sound effects. This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system improves the stability of sound at each channel and minimizes crosstalk between channels, so that positioning of sounds around the room is more accurate compared with conventional analog signal processing systems. In addition, this unit features a built-in automatic input balance control. This always assures you the best performance without manual adjustment.

Dolby Pro Logic Surround + DSP Dolby Surround sound system 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, and other factors of your listening room are 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 Surround sound field. The combination of Dolby Pro Logic Surround and DSP is used on the sound field program “ PRO LOGIC ENHANCED”. CINEMA DSP The YAMAHA “CINEMA DSP” logo indicates these programs are created by the combination of Dolby Pro Logic and YAMAHA DSP technology.

Above all, the positioning of the speakers is important because it controls the whole sound quality of this system. Position the speakers on the basis of your listening position by following the instructions in this section. Front L Center Speaker configuration Front R This system employs a 6-speaker configuration: 2 front speakers, 2 rear speakers, a center speaker and a subwoofer. The front speakers are used for the main source sound plus the effect sounds. The rear speakers are used for the effect and surround sounds, and the center speaker is for the center sounds (such as dialog.). The subwoofer is for reinforcing low frequencies of the main source sound and the center sound. Subwoofer Rear L Rear R Placing speakers Front speakers: On both sides of the TV and at almost the same height as the TV. Rear speakers: Behind your listening position, facing slightly inward. Nearly six feet (approx. 1.8 m) up from the floor. Center speaker: Precisely between the front speakers. Subwoofer: The position of the subwoofer is not so critical because low bass tones are not highly directional. Front R Center Subwoofer Front L TV set Rear R Rear L Note Although FRONT, REAR, and CENTER speakers are magnetically shielded, there may be some influence on the TV picture depending on the type of TV or the placement of the speakers.

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. 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 DSP program. 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. 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 the DSP program, PRO LOGIC or PRO LOGIC ENHANCED. Note The channel level balance between the left and right rear effect speakers may vary depending on the sound field you are listening to. This is because most of these sound field recreations are actual acoustic environments. PROGRAM PRO LOGIC ENHANCED PRO LOGIC CONCERT SPORTS MONO MOVIE FEATURE This program is used for playing 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 movie theater. This effect creates a wide surround sound field, and expands the sound stage with an improved presence image. This program is used for musical based movies, as well as drama and comedy based movies. This program is also used for playing of sources encoded with Dolby Surround. The application of a sophisticated digital signal processing system reduces crosstalk and directs or steers the sound source more smoothly and precisely, as compared to conventional types. This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the orchestra and stage are ideally recreated, making you feel as if you were in an actual concert hall. This program is ideal for enjoying sports programs which take place in arenas, indoor stadiums, or other venues. This program is designed specifically to enhance mono source programs. Compared to a strictly mono setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an immediacy to the overall sound. It is particularly effective when used with old mono movies, news broadcasts and dialog. E-20  AV-S7(E)17-24 9/11/0 9:07 AM Page E-21 USING THE AV-S7 1 Press the POWER button.
