FRONT PANEL DESCRIPTION 

1

 SIGnal present/OverLoad LED.

 This bi-color LED lights green for a -30 dBu signal, and turns red when the Input is within 3 

dB of clipping.

2

 

MONO MIC/LINE INPUT LEVEL controls 1-4

 determine the MIC/LINE preamp gain and mix level to be assigned to the A, 

A+B, B Outputs.

3

 

ASSIGN switches determine between the A, A+B or B 

Outputs for each MIC/LINE input.

 

4

 STEREO LINE INPUT LEVEL controls 5-8

 determine the amount of stereo or mono line Input routed to the Outputs.

5

 MONO switch 

mixes the A and B sides of each STEREO LINE input together. When active, the associated LED lights, and the A 

and B Inputs for that channel have exactly the same level.

 

6

 

OUTPUT OverLoad LED

 illuminates within 3 dB of an approaching overload condition. To avoid this, the associated OUT-

PUT LEVEL control may be decreased, or the problem-causing individual Input Level may be lowered.

 

7

 

A and B OUTPUT LEVEL controls 

set the Output Level for A and B outputs.

 

8

 

POWER LED

 is lit whenever adequate power is applied to the unit.
