The PAC45J adds complete audio control to the PAC45 family of audio controllers from PS Engineering. 16 push/pull knobs allow the user to control the volume of 8 COM radios and up to 8 navigation receivers or other switched audio inputs.

With a total of 8 COM inputs, MultiTalker® provides up to 9 unique positions so that each radio has its very own location within the stereo headset.

Up to four control heads can be connected to the HUB45AR hub. Control heads can be mixed and matched to configure the installation in numerous ways. For example, the Pilot and Copilot position can use the PAC45J control heads for complete audio control, and the 2 observer positions can use the space saving PAC45A control heads.

Like all the PAC45 series products, the hub is the central wiring location for all of the radios with a simple RS-422 serial bus connected to each control head, making the wiring significantly easier when compared to analog audio controllers.

The PAC45J integrates Receive Audio Indicator (RXI) inside the audio panel. Additionally, there are two built-in 10 watt speaker amplifiers for cockpit and public address.

Up to 9 audio alerts are also available, and through the use of IntelliStore™ each of these inputs can be custom recorded. Either rising, falling, or Sonalert inputs can activate these alerts. Once acknowledged, they are reset and then begin monitoring the inputs again. Sonalert triggers will remain active until the Sonalert voltage is removed.
