Audio Output Gain Adjustment
The default audio output gain is unity. However, to accommodate lower or higher level
sources it is possible to introduce gain or attenuation on a per channel basis. Each audio
channel has an adjustable gain range from -24dBu to +24dBu in 0.5dB increments. This is
set using the remote Control ports. Once set, this value is stored and reloaded each time
the unit is powered on.
