Overview

For Experimental / LSA / Non-Certified Aircraft only.

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, copilot, 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 copilot 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.

Q&A

Q: Are the PM 500 EX and PM 501 essentially the same unit? If not, what are the differences? In the search, 501 and 500 EX have the same PN. Thank you alex

Yes, the PM 500EX is the new name for the PM 501. The FAA required this name change to clarify experimental use only.

Q: Whats the difference between PM 500 and 1000 II beside TSO? Im building an experimental so certification is not and issue

Per P.S Engineering: aside from one being for experimental aircraft the other is TSO, the key differences are:
1000 II comes with the Jack Kit and can be multiple box (expanded)
PM 500: No Jack Kit and can only be single box (not expandable)
