INPUT BALANCE CALIBRATION
Pressing the same input source number will make “INPUT BAL
CENTERED” show in the bottom display row. Rotating the volume
control will simultaneously change the display and the main output’s
balance so that the action can be monitored or measured.
For example, setting the display to “R -9.0dB” will make the left
channel louder than the right channel. A maximum of -12 dB may be
set.
Again pressing the same input source number will end the
programming of this input and initiate a power up sequence.
