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 Bluetooth
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 positions, and
allow 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 microphone
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 (eight-station in -0202 with expansion unit) voice activated (VOX) intercom is included in the
PAR200A. This system has PS Engineering’s patented
IntelliVox®
circuitry that eliminates manual adjust-
ments. 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 controls the intercom volume level for the all headsets, while the
large knob controls the VHF Com radio volume. Intercom squelch is automatic.
A concentric rotary data input knob on the right side of the unit controls the TY9XL VHF COM radio fre-
quency selection.
