ACCOMMODATES UP TO 6 AVIATION HEADSETS
DC-COM Model 500 is a two-six place voice-activated (VOX) intercom.

INDIVIDUAL VOX CIRCUITS FOR EACH HEADSET
Each place has an independent VOX circuit. Only the microphone spoken into will be activated, all other microphones remain silent (off) reducing unwanted background noise.

VOICE-ACTIVATED INTERCOM
The DC-COM Model 500 provides two superior squelch circuits that are easily set for optimum VOX operation in a wide range of noise environments. The circuits are controlled by the SQUELCH control knobs.

PRIORITY TRANSMISSION
The DC-COM Model 500 is shipped preset for Pilot Priority Transmission. If the Pilot is transmitting the Co-pilot cannot transmit, or if the Pilot wishes to transmit he can pre-empt the Co-pilot's transmission.

TRUE STEREO SYSTEM
The unit comes factory set for mono at all locations. True stereo, with left and right channels at any location, is accomplished during installation by resetting jumpers within the unit. Frequency response 20 Hz to 1O KHz.

TRUE FAIL-SAFE
DC-COM Model 500 has built-in Fail-Safe. If power is removed from the unit or the unit is turned off, the Fail-Safe is automatic. In Fail-Safe, the Pilot is connected directly to the COM 1 port of the intercom. There is no inter-cabin communication though the unit in Fail-Safe mode.

OPTIONAL ATC/AUX. SWITCHES
The DC-COM Model 500 has built into it the muting of AUX. upon com radio reception. If you want to override this feature, you may add the optional ATC/AUX. switches external to the unit. In the ATC mode, the com radio reception mutes the AUX.; in the AUX. mode, com radio reception is heard with the AUX.
