Each circuit can be Intercom or IFB in any combination
Circuits linkable, A+B or A+B+C, with front panel switch
Each circuit may have its termination circuit lifted via rear panel DIP switch
Independent level control of program audio for each circuit, with an LED VU meter for each
Mic switch on each circuit can be quickly tapped for locking or held and released for momentary
Internal power supply is internal, completely linear (except for microprocessor functions) with 2.7A output. Toroidal transformer. Extensive monitoring and auto control.110/220V, 50/60Hz
Full duplex, hands-free operation in moderately noisy environments. Requires plug-in gooseneck microphone. Particularly noisy environments require a noise canceling differential gooseneck mic.
Paging output (balanced and isolated) on rear panel activated by front panel momentary push button. Dry contacts (rear panel) simultaneously closed. Requires gooseneck microphone
Front panel 4-pin XLR may be used for gooseneck microphone or headset
Front panel green LED indicates presence of 24VDC across the circuits
Three front panel red LEDs report status of each circuit. In case of trouble (short, overheating etc.) the appropriate red LED illuminates and flashes. Repairing the problem automatically restarts the circuit.
