Overview of the Digital Signal
Processor (DSP) Function
The DSP can digitalize and process the audio
signal with high speed thus enabling you to
adjust the acoustic characteristics of the source
sound without losing the sound quality.
With the DSP unit you can control the audio
output and adjust the acoustic characteristics
according to your preference.
Notes

are connected, the reproduced sound may become
distorted if the audio output signal of the graphic
equalizer is boosted too much. In this case, press preset
number button 8 while pressing the SEL button.
This will reduce the volume, but the distorted sound can
be suppressed. To cancel the mode, press these buttons
once again. (In case the optional XDP-USOD is
connected by the optical cable, the volume will not get
reduced even if you press preset number button 8 and the
SEL button.)
