FRONT PANEL CONTROLS

(4) Audio Input Impedance Switch (S5)

This 3 position toggle switch is used to change the input impedance

of the Mic and Aux Inputs (19,20 & 21). Input Impedances of 200 ohms, 600 ohms and 50K ohms ( HI-Z)may be selected.

(5) Mic In Gain (R12)

This potentiometer, when turned clockwise, can increase the Audio Input signal levels up to about +40dBv. The mic gain should be changed while speaking into the microphone, until 3 or 4 green Bar Graph (7) LED’s are illuminated. Audio levels should be maintained in the green and yellow ranges of the LED Bar Graph(6) .

(6) LED Bar Graph

The 10 segment LED Bar Graph indicates peak to peak EQplus internal audio levels. The position of the Equalizer (7) and Compressor / Downward Expander (10) switches control what internal function is being indicated. The tables below defines what the LED Bar Graph is indicating.
