1.3 EQUIPMENT DESCRIPTION
The PAR200A is a state-of-the-art audio isolation amplifier and audio selector that contains an automatic
voice activated (VOX) intercom system and serial data control/indication for a Trig VHF communications
receiver. It can switch two transceivers (Com 1, Com 2) and two receivers (Nav 1, Nav 2).
A Bluetooth ® TELEPHONE feature allows the PAR200A to interface the aircraft headset(s) and Blue-
tooth enabled cellular devices.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited by regulation.
PS Engineering is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the PAR200A must be interfaced with an approved system.
There are four unswitched inputs, available for traffic or EGPWS, autopilot disconnect tones, and/or radar
altimeter warning.
Pushbutton switches select one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PAR200A has the ability to allow the pilot to transmit on
Com 1 while the copilot can transmit on Com 2. A fail-safe mode connects the pilot headphone and micro-
phone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-safe)
position. Unswitched input #1 is also provided to the pilot headphone in fail-safe
A four-station voice activated (VOX) intercom is included in the PAR200A. This system has PS Engineer-
ing’s patented IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorporates
pilot isolate, all and crew modes, two independent stereo music inputs with "SoftMute™". Volume control
is through the concentric front panel knobs and a pushbutton intercom mode switch. The small knob con-
trols the intercom volume level for the all headsets, while the large knob controls the VHF Com radio vol-
ume. Intercom squelch is automatic.
A concentric rotary data input knob on the right side of the unit controls the TY91L VHF COM radio fre-
quency selection.
