PM500EX – 4 Place Experimental intercom

SKU: 11801 Category: Tags: , , Brand: PS Engineering

Available on backorder

AUD $865.00 

Low Cost, Four Channel Panel Mounted Intercom System For Experimental Aircraft.

Affordability, ease of use, plenty of audio power, and high reliability were the primary engineering considerations for the PM500EX, PS Engineering’s lowest cost intercom.

Available on backorder

The PM500EX provides all basic intercom capabilities plus many of the most advanced features usually only found in more expensive models.

Among the best features: Individual output amplifiers for pilot, co-pilot, and passengers 1 and 2, giving enough audio punch to allow communications in very noisy environments.
Voice Operated Relay (VOX) circuitry prevents mic audio from getting through the intercom until someone speaks or triggers the VOX open switch.
Automatic fail-safe interconnect to the aircraft radio wires the pilot's headset to the aircraft radio in the event of disrupted power or related failure.
Input jack giving pilots and passengers the option to listen to music during flight. During intercom activity, a mute feature will allow communications without distraction.

Note that radio reception will NOT mute the music.
Pilot isolate mode allows the pilot to communicate without interruption during critical phases of the flight while passengers talk and listen to music.
Separate pilot and co-pilot transmit capabilities ensures that only the person pressing the PTT will be heard over the radio.

With the PM500EX, you get years of trouble-free operation in a very inexpensive unit.
