The Sound Field Processor built into this system enables you to enjoy listening to a source with an ambience of actual concert hall
or three-dimensional acoustics. This system provides preset sound field programs shown below. You can enjoy an excellent sound
field by selecting one of them, and adding desired adjustments.
This system also incorporates a Dolby Pro Logic Surround decoder for multi-channel sound reproduction of Dolby Surround encoded
video sources. The operation of the Dolby Pro Logic Surround decoder can be controlled by selecting a corresponding sound field

Various sound control
Sound field programs
This program is used for playing sources encoded with Dolby Surround.
Dolby Pro Logic Surround uses four discrete channels and five speakers to reproduce realistic and
dynamic sound effects: two main channels (left and right), a center channel for dialog, and a rear
channel for special sound effects. The rear channel reproduces sound within a narrow frequency range.
This program is used for simplified play of Dolby Surround encoded sources. With this program, sound
effects are output from the left and right front speakers and no sound from the rear speakers.
YMERSION is Yamaha’s proprietary technology that enhances the spread of a normal stereo source
play sound, creating three-dimensional acoustics using only two speakers.
This program presents you with an ambience of actual concert hall by adding effects as sonic reflections
or reberverations that create sound environment of a hall. Sound effects are output from the front and
rear speakers. Orchestra and opera music is suited for this sound field.
