What Is the Digital Signal Processor ?
The STR-GX909ES/STR-GX808ES incorporates digital
signal processing circuitry which consists of a digital
surround processor and a digital parametric equalizer.
® The digital surround processor electronically reproduces
the acoustics of various listening situations.
¢ The digital parametric equalizer controls the output level
of specific frequencies to finely adjust the frequency
responses.
These 2 digital sound effects allow you to create the
optimum sound quality and sound atmosphere in your room.
10 recommended sound field programs (combination of
settings of the surround and parametric equalizer have been
preset in the factory. Since these programs are appropriate
for the most types of music and listening situations, you can
enjoy the digital sound effects by just selecting the sound
field programs according to the program source. And you
can also manipulate various parameters to finely tune the
factory-preset settings to your room, or create original sound
effects as you like. (Pages 34 to 39)
