Section III OPERATION 

GENERAL INFORMATION 

3.1 SCOPE 

 

This section provides detailed operating instructions for the PS Engineering PCD7100-I, Intercom Systems 
with integrated Compact Disc (CD) player, and PCD7100-P, CD player only. Please read it carefully be-
fore using the equipment so that you can take full advantage of its capabilities.

 Power Switch (Fail Safe Operation) 

Unit power is turned on and off by pushing the intercom volume knob. In the 

OFF

 or "

EMG

" position, the 

pilot is connected directly to the aircraft radios. This allows communication capability regardless of unit 
condition. Any time power is removed or the unit turned 

OFF

, the intercom will be placed in the fail-safe 

mode.

3.3.1  Intercom Volume Control (11950, 11951, 11956, 11957) 

The ICS volume control knob (left side) adjusts the loudness of the intercom for the pilot and copilot only. 
It has no effect on selected radio levels, music input levels or passengers' volume level.  

Adjust the radios and intercom volume for a comfortable listening level for the pilot. Most general aviation 
headsets today have built-in volume controls; therefore, passenger volume can be adjusted at the headset. 

 

3.3.2 

IntelliVox

® VOX-Squelch 

No adjustment of the 

IntelliVox

® squelch control is necessary. Through independent signal processors on 

each microphone, the ambient noise appearing in all microphones is constantly being sampled. Non-voice 
signals are blocked. When someone speaks, only their microphone circuit opens, placing their voice on the 
intercom. 

The system is designed to block continuous tones, therefore people humming or whistling in monotone 
may be blocked after a few moments. 

For best performance, the headset microphone must be placed within ¼ inch of your lips, preferably 
against them. It is also a good idea to keep the microphone out of a direct wind path. Moving your head 
through a vent air stream may cause the 

IntelliVox

® to open momentarily. This is normal. 

For optimum microphone performance, PS Engineering, Inc. recommends installation of a Microphone 
Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but will 
improve the overall clarity of all your communications.
