Communications Receive (RCV) Selection (3)
To listen to the other radio, press the upper button, in the RCV (receive) sec-
tion. When a com is selected for receive, it will stay selected until manually
deselected, even if you select, and then deselect its transmitter.
Unless the audio panel is in “split” mode, the PMA8000BT gives priority to
the pilot’s radio Push-To-Talk (PTT).
If the Monitor function is activated (Function B), the audio from this radio
will be muted when the primary radio (selected for transmit) is receiving a
signal.
In TEL mode, the pilot is con-
nected to the cell phone, but still
hears the COM radios selected.
The radio PTT will switch the
mic to the selected com, and
allow continued aircraft commu-
nications to continue. (See Page
6—TEL—for more details)
Audio Selector (4)
These buttons select the switched navigation receivers. The
DME input (if present) is also shared with AUX. In SPLIT
mode, only the pilot will hear selected navigation audio.
Cockpit Speaker (5)
This switch will place all selected audio on the cockpit speaker when this
switch is selected. In “Split” mode, the speaker carries the same audio as the
pilot.
Depending on installation, important audio alerts such as radar altimeter or
autopilot disconnect will come over the speaker even if it is not selected,
while other unswitched inputs, will only be present if the SPR button is se-
lected. Consult your professional avionics installer for these important con-
figuration details.
Intercom Operation
IntelliVox® VOX-Squelch
IntelliVox® is PS Engineering’s proprietary intercom squelch control.
Through the use of digital processors, each microphone is monitored, and
opens instantly when human speech is detected. This results in seamless con-
versations aboard the airplane for crew and passengers, without syllable clip-
ping or fatigue-inducing noise.
No adjustment of the IntelliVox® squelch control is necessary. There is no
