INSERTING AN INPUT LINE PAD
To insert a 40 dB line pad for a given microphone input, remove the
resistors specified in the following table.
DISABLING THE MASTER LEVEL CONTROL
The Master gain control can be disabled to prevent tampering. Refer
to the following table for gain levels and resistor values.
Procedure:
1.
Remove resistor R9203.
2.
Install new resistor at jumper R9173.
CHANGING THE LIMITER THRESHOLD
To change the limiter threshold from the preset value of +16 dBu,
modify the circuitry according to the following table.
CHANGING HOLD TIME
To change the hold time from the preset value of 0.4 seconds, modify
the circuitry according to the following table.
LOCAL AUX OPERATION
This modification removes the auxilliary audio from the SCM410
outputs. Auxilliary audio originates from the aux inputs of the Shure
SCM810, SCM800, and AMS8100 mixers when linked to the SCM410.
Procedure:
1.
Remove resistor R9187.
