PAC45 Pilot Guide
fies up to nine locations. This helps the crew to better comprehend speech
by locating it in a manner more easily differentiated by the human brain.
Intercom and other audio is not spatially processed, only the six communi-
cations transceivers.
You must use stereo headsets, in stereo mode for this feature
.
MultiTalker® places the communications receiver audio in one of nine ap-
parent locations in the crew
’
s headset. This has been scientifically shown to
allow the brain to focus on multiple conversations and improve comprehen-
sion for the listener.
Pressing the HRTF button toggles the PAC45 MultiTalker spatial function
on (receiver sources distributed) or off (receiver audio sources neutral). The
HRTF button on the pilot and copilot panels control the function for the
user of that panel.

the locations for the six re-
ceive audio locations for all
users. 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 desired 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 will
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.
