PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual Section I – GENERAL INFORMATION 1.1 INTRODUCTION The PMA8000B-MP3 represents another evolutionary step in cockpit audio control and intercommunications utility. Using our patented IntelliVox® design, front panel utility jack, and pilot programmable co nfigurations, and internal MP3 player, this marks the next level of audio control.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual A six-station voice activated (VOX) intercom is included in the PMA8000B-MP3. This system has PS Engineering’s patented IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorporates pilot isolate, all and crew modes, two independent stereo music inputs with "SoftMute™". Intercom volume control is through two concentric front panel knobs and a pushbutton intercom mode switch.

PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual Section II - INSTALLATION 2.1 2.1.1 GENERAL INFORMATION SCOPE This section provides detailed installation and interconnection instructions for the PS Engineering PMA8000B-MP3 Audio Selector Panel/Intercom/ with internal Marker Beacon. Please read this manual carefully before beginning any installation to prevent damage and post installation problems.
PS Engineering PMA8000B-MP3 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-MP3.
PS Engineering PMA8000B-MP3 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-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual Some avionics do not provide a separate audio low, and may introduce additional electrical noise into the system. For best results, connect the audio low from the audio panel to the radio ground, using one conductor of the twisted-shielded cable. 2.4.5.1 Speaker Load The PMA8000B-MP3 contains one speaker amplifier.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.8 "Swap" Mode When a momentary, normally open, push-button switch is connected between pin 20 on the J2 connector and aircraft ground, the user can switch between Com 1 and 2 by depressing this switch without having to turn the mic selector switch. This yoke-mounted switch eliminates the need to remove your hands from the yoke to change transceivers.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual NOTE The front-mounted utility jack is intended for portable equipment that is advisory in nature. It is NOT INTENDED for use as a primary warning channel. Audio of importance MUST ALWAYS be hard-wired into the unswitched inputs of the audio panel. 2.4.11 Public Address Mode By pressing the Mute and SPR pushbuttons at the same time, the PMA8000B-MP3 will be placed into public address (PA) mode.

PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.10 Post Installation Checkout After wiring is complete, verify power is ONLY on pins 8 and 9 of the J2 and airframe ground on connector pins 10 and 11. Failure to do so will cause serious internal damage and void PS Engineering's wa rranty. 2.11 Unit Installation To install the PMA8000B-MP3, gently slide the unit into the mounting rack until the hold -down screw is engaged.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual 13. Push the SPR button. Verify that all selected audio is heard in the cockpit speaker. Verify that the audio mutes when the mic is keyed. 14. Verify that the appropriate LED in the lower button row blinks when either push to talk is keyed. 15. Verify proper Intercom system operation in the ALL, ISO and CREW modes (see Table 3-1). 16.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.13 Final Inspection Verify that the wiring is bundled away from all controls and no part of the installation interferes with ai rcraft control operation. Move all controls through their full range while examining the installation to see that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in acco rdance with good practices, with adequate strain relief.
PS Engineering PMA8000B-MP3 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-MP3, 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 cap abilities. This section is divided into five sections covering the basic operating areas of the PMA8000B-MP3 systems.
PS Engineering PMA8000B-MP3 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-MP3 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-MP3 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 tran smit capability on the other selected transceiver. In ISO intercom mode, when the PMA8000B-MP3 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.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual Use "HI" sensitivity initially. This allows you to hear t he outer marker beacon about a mile out. Then touch the smaller MKR button to switch into Low Sensitivity mode. “LO” sensitivity gives you a more accurate location of the Outer Marker.
PS Engineering PMA8000B-MP3 Audio Selector Panel and Intercom System Installation and Operator’s Manual Adjust the radios and intercom volume for a comfortable listening level. Most gener al aviation headsets today have built-in volume controls; therefore, volume also can be further adjusted at the individual hea dset. 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.
