intelligence into the PMA8000B MP3, too.
Smart Jack Function
When the PMA8000B MP3 has a signal on music #1 input coming in
from the rear connector, or the MP3 player is active, the front panel
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 MP3 from doing its main job.
