Introduction
Congratulations on purchasing the new FlightTech ITC-404SP panel mount intercom. The ITC-404SP is de-
signed using the latest in noise canceling and printed circuit board technology. With proper installation, the
ITC-404SP will give many years of reliable cockpit communications for both the pilot and passengers.
FlightTech ITC-404SP Features
Enhanced Noise Reduction
The ITC-404SP features Enhanced Noise Reduction or ENRI. The ENRI feature will eliminate or
greatly reduce all background noise picked up the headsets microphone. Sounds such as engine noise and
wind noise that are commonly heard with voice operated intercoms when the microphone circuits are open,
are eliminated with ENRI.
Pilot Isolate
At times, it is desirable for the pilot to listen to ATC and allow the passages to commutate while not
interfering with the pilot. The Pilot Isolate switch in the “ALL” position allows the pilot to hear and talk to
every one connected to the intercom. In the “PILOT” position, the pilot will only hear the communication
radio audio.
Pilot & Co-Pilot PTT
The ITC-404SP includes PTT functions for both the Pilot and Co-Pilot and depending on which PTT
switch is enabled, either the Pilot or Co-Pilot will key the communications radio and be able to speak.
Auxiliary Audio Stereo Input
A Stereo Auxiliary input is provided allowing a tape or CD player to be connected to the ITC-404SP.
The audio output is Stereo and requires Stereo headphones for proper operation.
Auxiliary Audio Muting
The Auxiliary audio will mute when audio form the Communication radio or Intercom audio occurs.
Cellular Phone Interface
The Cell Phone interface will connect the pilots headphones to a Cellular Phone. Unlike headphone
with built in cell jacks, the audio to the phone from the pilot headset is derived from the intercom audio
processor, eliminating engine noise or other background noise that may be heard during the phone call. Con-
nection between the ITC-404SP and the cellphone is done through a patch cord with 2.5mm plugs.
Fail Safe
In the event that power should fail to the intercom, the pilots headset is automatically connected di-
rectly to the radio microphone and headphone inputs.
