EQUIPMENT DESCRIPTION
The PAC15EX 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 by a integrated avioncs controller, such as
an MFD. It can switch two transceivers (Com 1, Com 2) and two receivers (Nav 1, Nav 2).
There are four unswitched inputs, available for traffic or EGPWS, autopilot disconnect tones, and/or radar
altimeter warning.
Remote MFD control can select the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PAC15EX 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 mi-
crophone 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 PAC15EX. This system has PS Engi-
neering’s patented
IntelliVox®
circuitry that eliminates manual adjustments. The intercom system incor-
porates pilot isolate, all and crew modes, two independent stereo music inputs with "SoftMute™".
