3.10.2.1 Smart Jack Function
When the PMA5000EX has a signal on music #1 input coming in from the rear connector, the front panel
jack automatically becomes a Priority Advisory input, and is heard in the crew headphones.
NOTE
The front jack is no substitute for the installation of alerts such as the GPS waypoint or autopilot tones.
These still must be hard wired into the back by your installer.
3.10.3 Music Input
When used as a music input, the front panel jack is treated as Music #1. A patch cord is available with 2.5
mm to 3.5 mm (3/32 to 1/8” ) adapter cord (PS Part Number 425-006-2535).
3.10.4 Alternate Music Distribution
The alternate music distribution allows you to configure your music to be either independent of the inter-
com mode, or to make Music 2 dependent on the intercom mode. This more is controlled by an optional,
external switch, or by an installation strap, which makes the mode non-user selectable.
In Alternate Music Distribution, Music 2 will be active only when the intercom is in the CREW mode,
and only the passengers will hear it. This distribution is similar to other brands of audio panels. It allows
the passengers to have their music source come on only when they are not hearing the crew.
