The PA-400ST intercom is a portable design that has been used successfully in general aviation for over 20 years. No other intercom on the market has the features and capabilities of the PA-400ST. The Pilot USA PA-400ST Intercom contains a 3-way control switch, a Pilot-Isolate switch for enhanced cockpit communications, and separate volume controls for pilot and crew. The PA-400ST has increased audio levels along with an auto power shut-off if the pilot's headset is disengaged. This Stereo version can be used with monaural or stereo headsets, or any combination of headsets. This particular series of the PA-400ST has been recently modified to include a cell phone jack designed for "Smartphones" as well satellite phones.
