Unswitched Summed Audio
PXE7300 units have four audio inputs that are summed together and presented to the audio output, J1 pin
18 WRT V.
NOTE: These can be used to implement additional audio warnings when connected to the appropriate
Unswitched audio input of an audio panel. This includes Autopilot warnings, TAWS, GPS alerts, Radio
Altimeter, etc.

Aux Entertainment Audio and AUX Enable
Besides the disc and AM/FM, the PXE7300 has the ability to act as a switching control for an additional
entertainment input (DVD, external XM Radio tuner, etc.).
The audio input is Pin 16 (R), Pin 17 (L) with respect to Pin K.
To enable the mode, add an internal jumper on the pins marked J2, or apply a ground to Pin 20 of the rear
connector.

Special Playback Function (Option 1 only)
The PXE7300 can be used to play up to five specially encoded audio tracks. This can be used for passenger
briefings, tour narration, etc. These files will play automatically when a specific pin is grounded on the init
connector, activated by a switch or logic input that pulls either to ground or to a positive voltage if the unit
is configured properly.
In order to use a positive voltage (>4 VDC), the unit must have jumpers installed at the following loca-
tions:
Input 1 - R134
Input 2 - R146
Input 3 - R155
Input 4 - R135
Input 5 - R147
Recorded MP3 files must be stored on a disc with the volume label 7300. The individual files shall be la-
beled 0001.mp3, 0002.mp3, and so on.
