jack automatically becomes a Priority Advisory input, and is heard in
the crew headphones.
This input will NOT be muted by radio or intercom.
Music Input
When used as a music input, the front panel jack is treated as Music
#1. However, thanks to the function controls, it can be distributed to
all users, regardless of the intercom mode.
Smart Function Keys (SFK)
With Virtual Tech Support, the configuration process is self-directed.
Once you’ve set up your system, you don’t need to change it again,
unless you want to. The unit will always remember your settings.
Note: VTS annunciations will be stopped by any audio received on
the com radio selected for transmit.
These functions are non-essential and non-required and as such are
only an accessory capability. They don’t affect the audio panel’s pri-
mary function as a selector panel, aircraft intercom, or marker beacon
receiver. You can’t do anything with these buttons to prevent the
PMA8000B from doing its main job.
Looking at the front panel you’ll notice that the TEL, Aux, Mute and
SPR buttons have “Function” assignments.
To use these function keys A, B, C – press and hold “F” and then
press the desired key, “A” “B” or “C”.
