OUTLINE OF THIS SYSTEM

SYSTEM CONFIGURATION
This system is a multi-channel audio system which consists of the units shown below. By driving 6 speakers, the built-in digital sound field processor (DSP) creates various kinds of Yamaha original digital sound fields simulating an actual concert hall, live house, etc. When watching a movie source, the built-in Dolby Pro Logic Surround decoder and the digital sound field processor turns your room into a movie theater with tremendous impact. Ultralow bass reproduced by the subwoofer (SW-AV1) makes sound more real and more powerful. The built-in CD player and tuner provide you with effortless operation and high performance. You will be given great enjoyment in listening to music and watching TV with this system.

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. Manufactured under license from Dolby Laboratories Licensing Corporation. Dolby, Pro Logic, and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation.
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, 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 Surround sound field. The combination of Dolby Pro Logic Surround and DSP is used on the sound field program PRO LOGIC ENHANCED.

The YAMAHA CINEMA DSP logo indicates these programs are created by the combination of Dolby Pro Logic and YAMAHA DSP technology.
SETTING UP THE SPEAKERS English

SETTING UP THE SPEAKERS

USING DIGITAL SOUND FIELD PROCESSOR (DSP) English
USING DIGITAL SOUND FIELD PROCESSOR (DSP)
This system incorporates a sophisticated, multiprogram digital sound field processor. 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. 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.
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 to. This is due to the fact that most of these sound field recreations are actual acoustic environments.

Press the PROGRAM selector or button once or more so that the name of a desired program appears on the sound field program indicator. * Whenever you press the PROGRAM selector button, the program changes and is displayed as figured left. * Pressing the PROGRAM selector button changes the programs in the reverse order.

DIGITAL SOUND FIELD PROCESSOR (DSP)
The Digital Sound Field Processor (DSP) built into this system takes advantage of Yamahas 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 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? Todays advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are youll 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 youll 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. Manufactured under license from Dolby Laboratories Licensing Corporation. Dolby, Pro Logic, and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation.
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.

SETTING UP THE SPEAKERS English Center Speaker Installation
When installing the center speaker on the TV, be sure to secure the center speaker to the TV using the velcro strips provided so that it does not fall.

STAND BY INPUT 1 INPUT 2

Rough surface Smooth surface
Notes Do not place the center speaker on top of a TV whose area is smaller than the bottom area of the center speaker, as the center speaker may drop and cause personal injury. Although this center speaker is a magnetically shielded type, there may be some influence on the TV picture depending on the type of TV or the placement of the center speaker. In such a case, place the center speaker apart from the TV so that there is no influence on the TV picture. Be sure to remove all dust, debris, oil, and other substances adhering to the section where the velcro strip is affixed. If this section is dirty, the velcro strip will not affix properly, and the center speaker may move or fall. When peeling off the backing paper of the velcro strips, be careful not to touch the adhesive surface. Doing so harms the adhesion strength. If there is a gap between the center speaker and TV, turn and extend the adjuster on the bottom rear section of the center speaker so that the center speaker is stable.

USING THE AV-S7

This system incorporates a sophisticated, multiprogram digital sound field processor. 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. 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.
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. 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.
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.
