NOTE:
To compensate for higher output condenser microphones, the factory-set gain in the PHM position is 13 dB
lower than the gain in the MIC position.
Line-Level Output to Mic-Level Output
Procedure:
1. Short jumper X901.
2. Remove resistors R900 and R909.
Disable Mater Level Control
The Master gain control can be disabled so it cannot be tampered with. The following table indicates the resistor
value to be used for the desired gain.
Master Section Gain

Procedure:
1. Short jumper X901.
2. Remove resistors R900 and R909.
Change Limiter Threshold
All three threshold settings (+16, +8 and +4 dBm) can be changed. To shift the threshold down by 6 dB, resistor
Rwill be 82 kΩ. To shift the limiter thresholds up by 6 dB, R will be 330 kΩ.
Procedure:
1. Remove resistors R9177 and R9180.
2. Install new resistor R at jumper X907.
Local Aux Operation
With linked mixers, the Aux input from a modified mixer does not link.
Procedure:
Remove resistor R9024.
