1. Select ‘INS’ and set ‘MIX LEVEL’ to maximum.
2. Select
1. Measure the Left ‘Follow Mon’ Output. Adjust the oscillator level to obtain +24dBu, if necessary.
2. Adjust VR5 (‘0dB LEFT’) so that that the top left hand ‘red’ LED on the bargraph meter just illuminates.
3. Connect the oscillator to Insert Return Right.
4. Measure the Right ‘Follow Mon’ Output. Adjust the oscillator level to obtain +24dBu, if necessary.
5. Adjust VR4 (‘0dB RIGHT’) so that that the top right hand ‘red’ LED on the bargraph meter just illuminates.

X-Rack Master Module

F.5.1

Calibration Information The X-Rack Master module is factory calibrated and should only need calibration if a potentiometer or other component has been replaced or if it is suspected that there is a problem with calibration.

In each of the following instructions it is assumed that the lid of the X-Rack has been removed and that power has been applied. It is also assumed that, unless otherwise specified, all switches are released and all front panel potentiometers are at unity or minimum position as appropriate. The required accuracy for each adjustment will be specified along with the target value. All level and distortion measurements should be made with audio-band 20Hz to 20kHz filters unless otherwise specified.

All presets are accessible from the top of the unit.
