MICROPHONE INPUT
The MIC-AMP has two separate microphone inputs, each on an XLR connector.
WIRING DIAGRAM FOR IN/OUTPUT CONNECTORS
INPUTS XLR female pin 2 = in phase
pin 3 = out of phase
pin 1 = ground
OUTPUTS XLR male pin 2 = in phase
pin 3 = out of phase
pin 1 = ground
The MIC-AMP has two separate, low impedance, ground compensated outputs on a nominal operating level
of -10 dB and a maximum output level of +22 dBu.
