EQUIPMENT DESCRIPTION

The PAC45D is a state-of-the-art audio isolation amplifier and audio selector that contains an au-
tomatic voice activated (VOX) intercom system. It can switch six transceivers (Com 1 - 6) and six
receivers (Nav 1, Nav 2, MKR, and three additional inputs that can be individually labeled, for
use with ADF, DME, AUX, etc.).
There are four unswitched inputs, available for traffic or EGPWS, autopilot disconnect, and/or
radar altimeter warning.
A wired input is available for Satellite or Cellular telephone.
In addition, three alerts can be triggered by external sources to provide additional capability.
The individual volume controls select the receiver audio source provided to the headphones
when selected.
An eight-station voice activated (VOX) intercom is included in the PAC45D. This system has PS
Engineering's patented IntelliVOX® circuitry that eliminates manual adjustments. The intercom
system incorporates pilot isolate, all and crew modes, a stereo music input with "SoftMute™".
In the PAC45D, a Bluetooth® wireless interface is available for wireless telephone and music
connection.
