PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual Section I – GENERAL INFORMATION 1.1 INTRODUCTION The PMA8000B represents another evolutionary step in cockpit audio control and intercommunications utility. Using our patented IntelliVox® design, front panel utility jack, and pilot programmable configurations, this marks the next level of audio control. The unit is designed for outstanding ergonomics and visually defined mode annunciation and selection.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual The small volume knob controls the intercom level for the pilot and copilot, while the large knob controls the passenger intercom volume. Intercom squelch is automatic. A 3-light, 75 MHz Marker Beacon receiver is integrated in the PMA8000B. This provides the necessary Marker Beacon lights and audio indications necessary for that portion of an Instrument Landing System (ILS) approach.

Please read this manual carefully before beginning any installation to prevent damage and postinstallation problems.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual the unit aside in a safe location until needed. Install the tray using six clip nuts (475-630-0002), and six FHP 6-32 x ½" screws (475-632-0012). The audio selector panel must be supported at front and rear of the mounting tray. 2.3.4 Audio Panel Tray and Connector Assembly The rack connectors mate with two 44-pin connectors in the PMA8000B.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual Radiated signals can be a factor when low level microphone signals are "bundled" with current carrying power wires. Keep these cables physically separated. It is very important that you use insulated washers to isolate the ground return path from the airframe to all headphone and microphone jacks. 2.4.1.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.5 Audio Panel interface The PMA8000B is designed to interface with standard aircraft avionics, and presents a 510 receiver impedance. For best results, a twisted-shielded cable is recommended from the avionics audio source to the audio panel, with the shield grounded at the audio panel end.

For a list of phones that have been tested, visit www.ps-engineering.com. 2.4.7 Transmit Interlock Some communications transceivers use a transmit-interlock system. To fully utilize the Split Mode feature, this function must be disabled. Consult that manufacturer's installation manual. 2.4.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual NOTE Inputs 1, 2 and 4 are fixed (1:1), and any audio level adjustments must be made at the input source. Unswitched #3 has a variable adjustment control located on the bottom side of the unit. This control allows you to adjust the volume level of that unswitched input. Refer to Adjustments section. The front panel jack can be configured to act as a fifth unswitched input.

PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual Section III OPERATION 3.1 SCOPE This section provides detailed operating instructions for the PS Engineering PMA8000B, Audio Selector Panel/Marker Beacon Receiver/Intercom Systems. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This section is divided into five sections covering the basic operating areas of the PMA8000B systems.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual switched off. In essence, switching the mic selector will not override prior selection of COM receiver audio. In normal (not split) modes, the PMA8000B gives priority to the pilot’s radio Push-To-Talk (PTT). If the copilot it transmitting, and the pilot presses his PTT, the pilot’s microphone will be heard over the selected com transmitter.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual tions, and vice versa. In CREW mode, only the pilot and copilot are connected to the telephone. Passengers will not hear the telephone. The pilot and copilot will also have transmit capability on the other selected transceiver. In ISO intercom mode, when the PMA8000B is in the TEL mode, the pilot position is in the "Phone Booth." Only the pilot will hear the telephone, and only he will be heard.

Releasing the button returns to the last sensitivity. Pressing the marker mode select (“T/M”) for one second will also cause the marker audio to mute for that beacon. The next beacon received will re-activate the audio. 3.7 3.7.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.7.2.1 Mono headsets in Stereo Installation The pilot and copilot positions work with stereo or mono headsets. All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a PMA8000B Stereo installation, one channel will be shorted.

PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual Figure 3-2 Smart Function Keys These functions are non-essential and non-required and as such are only an accessory capability. They don’t affect the audio panel’s primary function as a selector panel, aircraft intercom, or marker beacon receiver. You can’t do anything with these buttons to prevent the PMA8000BT from doing its main job.
PS Engineering PMA8000B Audio Selector Panel and Intercom System Installation and Operator’s Manual When “Music one all headsets” is selected (press and hold Mute), music 1 (from the rear connector input, Pins J2 23 & 24 only) will be distributed to all headsets and is independent of the intercom mode switch. Therefore, even in the CREW mode, the passengers will hear Music 1, even though they will not hear the intercom or radios.
