INPUT LEVEL CALIBRATION
Pressing the same input source number will make “INPUT LEVEL
0.0dB” show in the bottom display row. Rotating the volume control will
change the display and the main outputs’ levels simultaneously. This
allows calibration of each input with test tones if desired.
For example, setting the display to “-6.0dB” will allow an input
which is twice the voltage of the other inputs to be heard at the same
level. A maximum of -24 dB may be set.
This is easiest to do if you start with the quietest source as your
reference, and then adjust the louder sources to match it.
