USING THE AV-S7 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. PROGRAM PRO LOGIC ENHANCED 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. PRO LOGIC 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. CONCERT 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. SPORTS This program is ideal for enjoying sports programs which take place in arenas, indoor stadiums, or other venues. MONO MOVIE 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
