COM Audio Selector (3)
Communication audio from the other radio, not selected for transmit, can be
heard by pressing the associated RCV button. You will always hear the au-
dio from the selected transceiver.
Swap Mode (Switch from Com 1 to Com 2 remotely)
With an optional yoke mounted, normally open momentary switch, the pilot
can change from the current Com transceiver to the other by pressing this
switch. To cancel "Swap Mode," either press the yoke mounted switch again,
or select a different Com with the XMT buttons.
IntelliAudio® Dimensional Audio
Various audio signals are presented to the DSP and processed to “appear” in
a different location to the crew.“Multi-Talker” (US Patent #7,391,877) speci-
fies up to nine locations. This helps the crew to better comprehend speech by
locating it in a manner easier differentiated by the human brain.
Intercom and other audio is not spatially processed, only the pilot and copilot
VHF COM audio.
The spatially processed dimensional sound in the PMA450 can be adjusted
to accommodate the user preferences.
This adjustment allows the Spatial
Audio inputs to be “relocated” on
any of nine (9) defined “Head Related Transfer Function” (HTRF) locations.
Push IntelliAudio → IntelliAudio Config to access. In the IntelliAudio®
mode, repeated pressing of the COM 1 or COM 2 line select buttons moves
the corresponding half-circle cursor to the locations relative to the listener
graphic in sequence.
Pressing the Done button exits the configuration setting mode. This setting
is recalled at system power up.
Com Monitor Mode
The PMA450 is equipped with a
Monitor function, which allows a
secondary com radio audio to be
muted by the primary radio (selected
for transmit).
To toggle the Monitor mode on and off, Press IntelliAudio → MONITOR
