Setting Monitor and Bargraph Levels:
Set the processor main fader and amplifier levels so the house speakers
are playing back at the normal listening level. Select some source material
like pink noise.
Set the “Processor/Amplifier” switch to “Processor”. With the monitor
volume to “7”, adjust the “Processor” trimpot for a comfortable listening
level. Set the bargraph trimpot for a reading in the middle range.
Set the “Processor/Amplifier” switch to “Amplifier”, adjust the amplifier
trimpot so the level matches the processor level.
