MAN –FD900X5
General Information
The FD900X5 is a 28VDC Wireless Audio Transmitter that represents a state of the art
audio experience. The FD900X5 has features that allow installation in the smallest of
mounting areas with the minimum of interface equipment. Built with retrofit aircraft
integration in mind, this transmitter can be mounted almost anywhere in the cabin.
The transmitter includes a separate PA input which interrupts all other channels when
transmitting.
Front View
Additional Information
This Wireless Audio Transmitter is for use exclusively with the FD24X5 Headsets (not
included, shown below). The headset operation information is included with the purchase
of a headset. A brief overview of headset operation is to turn the headset ON using the
ON/OFF/CHANNEL SELECT button. Press the CHANNEL SELECT button to select the
first channel. Adjust the VOLUME with the volume adjustment wheel. Subsequent channel
selections are obtained by pressing the CHANNEL SELECT button. The headset can be
turned off by holding the ON/OFF/CHANNEL SELECT button for 5 seconds.

Installation Instructions
All cabin entertainment equipment, such as the FD900X5, should be installed on a non-
essential bus and have a dedicated circuit breaker. It is a requirement that a switch be
installed so that the pilot can de-energize the system should it become necessary.
There are two #8 mounting holes located on the ends of the housing. It is sufficient to
mount by two attach points. Mounting locations in the cabin can be anywhere that is not
blocked or enclosed by metal surfaces. A drawer, cabinet, headliner or other suitable
location is fine.
When using the headsets, it is necessary to cycle the headset to get the channel.
Sometimes if the operator leaves his/her hands touching the headset the arms and body
will act like an antenna and the selection is more difficult. For optimum operation, press
the CHANNEL SELECT button and release.
It is important to match the output impedance of the audio sources. The input of the
FD900X5 should be low level audio such as that used for the inputs to home or automotive
entertainment systems. If one source is significantly stronger than another, it will cause
significant variation in the volume levels between channels. It may also cause frequency
bleeding and crossover between the audio channels.
In order to achieve the best frequency transmission, it is recommended that the unit be
mounted in the headliner or as close to the center of the aircraft as possible. Do not install
the unit near the nose or tail of the aircraft. It is also important not to install the unit near
any strobe circuits, inverters, or any high energy lines. Do not install the unit in a metal
enclosure. Note: some cabinets have a foil liner (grounding) which may limit the range of
the transmitter.

Power
The FD900X5 is a 28VDC device that requires .5 Amps of power to operate.
Audio Wiring Suggestions
The center conductor of coaxial cable should be high, and outer shield should be the
return/low.
Avoid routing audio wiring parallel to:
AC wiring
Strobe wiring
DC motor supply cables
Inverter cabling
Or any other potential noise source.
Wiring
Recommended cable for audio purposes is PIC 75 Ohm Coax, P/N V75268. This is a
lightweight, flexible, and low signal loss cable which meets FAA flammability requirements
of FAR 23.1359(d), FAR 25.853(a) and FAR 25.869(a)(4).
Similar aviation coaxial cable can be used from other vendors, as well.

Operation Instructions
The passengers will be able to access the different audio channels by momentarily
pressing the TUNE button found on the headset (not supplied). It is necessary to cycle the
headset through the different frequencies once turned on so that it may recognize the
transmitting frequencies.
If you recognize degradation in the quality of your audio or that you cannot channelize the
frequencies, check to make sure your headset batteries have sufficient power.
PA Interrupt
To use the PA interrupt, wire the audio coming from the cockpit microphone onto pins 19
and 20 of the D-Sub connector. Use a relay or push button to control the interrupt by
opening and closing the circuit. See diagram below.
The microphone impedance will activate the override and broadcast the audio on pins 19
and 20 to all wireless channels.
or relay
