Bass, treble, and loudness control

For optimum audio quality, the audio input levels and the bass, treble, and
loudness controls must all be set up properly. Input audio levels may need to be
adjusted depending on the variation of the output levels from different source
devices.
N By default these levels are set for the consumer product level of -10 dBV.
Bass and treble should be adjusted once the input and output levels have been
adjusted. These are adjusted by RS-232 control only, with a range from -10 dB to
+10 dB. By default the bass and treble have been set at 0 dB.
