Main AC input is protected by a circuit breaker 30W maximum power output Single NEMA receptacle in rear (unswitched, always on) First channel (MIC/TEL) is switchable for microphone or telephone inputs Second channel (PROGRAM) is switchable for program input screw terminals or AUX 3 dual combining RCA-phono connectors. Third channel (AUX 1) is for AUX 1 dual combining RCA–phono connectors. AC Supply Voltage: 120VAC 60Hz ±10% First channel (MIC/TEL): Switchable for microphone or telephone inputs. When the mute switch is turned on, a dynamic microphone or telephone input will mute the Aux 1, Aux 3, or Program inputs. Second channel (PROGRAM): Switchable for program input screw terminals or AUX 3 dual combining RCA-phono connectors. Third channel (AUX 1): For AUX 1 dual combining RCA–phono connectors.
