1.3 EQUIPMENT DESCRIPTION
The PAC45 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 field programmable alerts can be triggered by external sources to provide ad-
ditional capability.
The individual volume controls select the receiver audio source provided to the headphones
when selected to the “out” position.
An eight-station voice activated (VOX) intercom is included in the PAC45. This system has PS En-
gineering’s patented IntelliVOX® circuitry that eliminates manual adjustments. The intercom sys-
tem incorporates pilot isolate, all and crew modes, a stereo music input with "SoftMute™".
In the PAC45, a Bluetooth® wireless interface is available for wireless telephone and music con-
nection.
