Telephone Control - PS Engineering PAC45 System Pilot's Manual And Operation Manual

This adjustment allows the six Spatial Audio inputs to be "relocated" on
any of nine (9) pre-defined "Head Related Transfer Function" (HTRF) lo-
cations.
MultiTalker™ places the communications receiver audio in one of nine
apparent locations in the crew's headset. This has been scientifically shown
to allow the brain to focus on multiple conversations and improve compre-
hension for the listener.
Pressing the HRTF button toggles the PAC45 MultiTalker spatial function
on (receiver sources distributed) or off (receiver audio sources neutral).
Audio Location
The pilot panel can control the locations for the six receive audio locations.
Press and hold the HRTF button for > 1 second on the pilot's panel until the
HRTF button and all COM nomenclature start blinking green.
Rotate the COM receive volume
knob so the pointer indicates the
approximate location of the desired
location. A voice announcement
will accompany the knob rotation
with the clock positions. Received
audio shall then be presented from
that location.
Press the HRTF button again to exit
the mode. The audio Controller will
remember last state through power
cycles.
Navaid Audio Selection
Navigation receivers are selected in the same manner
as the communication receiver, push on/push off the
knob associated with the desired navigational aid, and
rotate to adjust the receiver volume.

Telephone control

The volume control selector connects the audio con-
troller to either a Bluetooth-enabled cell phone or a
wired cellular/satellite phone.
Push to pop out the volume control to select (answer or make
phone call) and adjust the receive audio volume.
To hear the ringer of the Bluetooth phone, the volume control
should be around the 12 o'clock position. Selecting the TEL
switch in the OUT position is not required.
