2.4.2 Power Requirements

The IntelliPAX was designed to work with the main intercom unit. No other power is required.
The Stand Alone unit is connected to a 1A breaker to the avionics bus (2A for dual).

2.4.3 Interconnection with main unit

Interface between the IntelliPAX and the main intercom is through a 4-wire shielded cable.

2.4.4 Auxiliary Inputs

An entertainment device can be connected to the IntelliPAX. Install a 1/8" music jack convenient to the
passengers to connect the stereo entertainment device into the system. A "Soft Mute" system is installed in
the IntelliPAX that will mute the music during conversation on the local intercom. Radio traffic or
conversation on the main intercom will not mute the music.
A second, monaural input is provided for other purposes, such as public address cabin briefing, or
providing radio interface for cases where the intercom does not have radio on the expansion bus (PM1000D
for example).
The PM1000D is not compatible with a music input, due to the specialized interface nature. If this is used,
connect the entertainment input to the IntelliPAX (11626) alone.
A soft mute inhibit switch (not included) can be installed between IntelliPAX connector pins 12 and 24.
Closing this switch places the IntelliPAX into Karoake mode.
WARNING: Local oscillators and other internal signals from CD or radio equipment can cause undesired
interference with VHF navigation and communication equipment. Before takeoff, operate the entertainment
device to determine if there is any adverse effect on aircraft systems. If any unusual operation is noted in

Post Installation Checkout

After wiring is complete, verify power is ONLY on pin 1 of the connector, and ground on pin 14 (with
main unit operating. Failure to do so will cause serious internal damage and void PS Engineering's
warranty. With all units plugged in and operating, verify that all active stations can communicate on the
intercom, and that any music sources are present, and the SoftMute inhibit control operates correctly (if
installed).
