FRONT PANEL CONTROLS & INDICATORS

External mic jack
The external mic jack is a balanced mic level input. This input is intended for use with a
dynamic or phantom powered microphone. It will not accept line level inputs without clipping.
The external mic input provides +48V on pins 2 and 3 for condenser mics while safely
supporting the use of dynamic mics.
Power switch
The Power switch turns the entire unit on or off. The switch cap doubles as a power indicator. If
it is not lit red, check the power supply connection or power source.
Talkback control
Use the talkback control to adjust the level of the mic to match the audio program signal. This
control can provide gain, so start out with the control set to the minimum level (fully counter
clock wise) and slowly increase it until you have sufficient level at the outputs.
