Feature
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 dialogue, 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
outputted from the front left and right 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 outputted from the front and rear speakers.
Orchestra and opera music is suited for this sound field.
