PMA-4000 Audio Panel

The PMA4000 is a 4-place panel mounted intercom with added capability for switching two communications transceivers and navigation receivers, as well as providing a speaker amplifier. The intercom features PS Engineering's exclusive IntelliVox® with individual volume controls for both the pilot and copilot.

• A multi-position mode switch allows the pilot to select either Pilot Isolate or All intercom modes.  

• The ISO mode isolates the pilot from the intercom, and connects directly with the aircraft radios. The copilot and passengers are free to have conversation and enjoy the entertainment without radio interruption. The pilot is not distracted by passenger intercom use and has control over the radio communications.  

• The "ALL" mode places everybody on a party line. Each person hears all intercom conversation and aircraft radio reception. Everyone hears the entertainment source as well.  

• The "Off" mode is part of the automatic fail-safe interconnect to the aircraft systems. If power to the intercom is disrupted, the pilot's headset is automatically connected to the aircraft radio. This permits continuous radio communications.

PMA-8000 Audio Panel

The PMA8000 is an audio selector panel for two VHF coms (including our split mode), a dedicated cellular telephone interface, a 6-place IntelliVox® stereo intercom with dual independent music inputs, and an internal marker beacon receiver with 3-light indicator.This new audio panel is the direct result of customer demand. Pilots want the performance and benefits afforded by our very popular PMA7000-series, but the time and expense for an upgrade can be daunting.  So PS Engineering, Inc. designed the PMA8000 to be a true plug-and-play replacement for the GARMIN GMA340.Having a cosmetic look that blends-in with a GARMIN stack, the integrated bezel and tactile push-button control will place it right at home with these very popular communications and navigation systems. Our patented IntelliVox® automatic intercom squelch system eliminates all of the traditional knobs or push buttons. Using digital processing, the system determines if the microphone is picking up voice, or aircraft noise. It opens instantly when voice is detected. This makes conversations seamless, even in a noisy aircraft.

PM-1000II Intercom

The PM1000II panel mounted, four-channel intercom gains the benefits of PS Engineering's 18 years of design excellence. This popular panel mount has advanced features found in only more expensive competitor's units. Some of its best features include:  

• Soft Mute circuitry is our standard-setting solution for managing the music volume levels against radio reception and transmission.

• 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.

• Separate pilot and copilot transmit capabilities ensures that only the person pressing the PTT will be heard over the radio. A red transmit light is illuminated when a PTT is pressed -- this also serves as a "stuck-mic" indicator.

• Independent intercom volume settings do not affect radio equipment volume levels, allowing better control over communications.

An optional digital recorder can provide up to one minute of storage of radio receptions. A continuous loop recorder, it does not record "dead air time", giving the pilots an option to store up to 16 messages at any one time.
