1.2 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.

1.3 Intercom Operation

1.3.1 Intercom Volume Control

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 radi o level s,
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 reduced at the headset.

1.3.2 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 perform ance, PS En gi neering, Inc. recommends
installation of a leather Microphone Muff Kit from Oregon Aero (1-8 00-888-

6910). This will not only optimize VOX performance, but will improve the
overall clarity of all your communications. If you experience clipping while
using the IntelliVOX®, remove the foam mic cover.

1.3.3 CD Music and Soft Mute Control

The right-side volume knob controls the loudness of the internal CD player.
The volume knob controls the CD music volume only, it has no effect on the

intercom or radio volume, or the secondary music input level.
This knob is also the Soft Mute control for the CD player. Normally, the mu-

sic is instantly muted during radio or intercom conversation, and returns
gradually to full volume when conversation stops. Pushing the knob once
will inhibit the soft mute, enabling a “Karoake” mode, where the music re­mains at he normal level for a sing-along. Push again to return to a soft mut­ing mode.

1.3.4 Mono headsets in Stereo Installation

Plugging a monaural headset into the pilot or copilot jacks has no effect other
than there will be no stereo left and right separation. Since all passenger
headsets are connected in parallel, if a monaural headset is plugged in to a
PCD7100 Stereo installation, one channel will be shorted. Although no dam­age to the unit will occur, all stereo-equipped passengers will lose one chan­nel. PS Engineering modifies headsets to add stereo capability, using high­fidelity speakers. Contact factory for details (1-865-988-9800 or www.ps­engineering.com).

1.3.5 Intercom Modes

On the left side of the intercom-versions is a 3-position mode switch that
allows the pilot to tailor the intercom to best meet the current cockpit situa­tion.
