Basic Calibration
The console has been calibrated at the factory to normal -10dBu and +4dBu levels and should not require field calibra-
tion. Because the console has BOTH -10dBu consumer AND +4dBu professional inputs and outputs for every feature,
level adjustment is usually not required. Also, it is better to adjust the level out of the source device than to adjust the
console levels. In this way, a source device can be moved from one studio to another without requiring recalibration.
MIC GAIN ADJUSTMENT
The only user level adjustments are on the two mic channels. These trim pots are set at the factory for typical microphone gain levels. These trim pots can
be adjusted if different mic gains are required. To adjust, the simplest method is to speak into the mic and adjust the trim pot with a small straight edge
screwdriver until the desired level is reached.
