PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual Section I – GENERAL INFORMATION 1.1 INTRODUCTION The PMA9000EX represents another evolutionary step in cockpit audio control and intercommunications utility. Using our patented IntelliVox® design, front panel utility jack, and pilot programmable configur ations, this marks the next level of audio control. The unit is designed for outstanding ergonomics and visually defined mode annunciation and selection.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual A six-station voice activated (VOX) intercom is included in the PMA9000EX. This system has PS Engineering’s patented IntelliVox® circuitry that eliminates manual adjustments. The intercom system inco rporates 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.

Please read this manual carefully before beginning any installation to prevent damage and post installation problems.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual are mounted to the tray back plate with #4-40 screws (475-440-1038), from the inside of the tray and the mounting block, 431-891-0100. Ensure that proper strain relief and chafing precautions are made during wiring and installation, using the cable clamp (625-001-0002).
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.1.1 Music Inputs and Noise PMA9000EX units utilize a differential input to help prevent noise from entering the music system. This feature is usually transparent to the installer, however, it is important that the appropriate music signal and ground connections are made directly to the dedicated music signal and ground inputs on the PMA9000EX. The power for IFE and audio panel should be a common bus.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.5.1 Speaker Load The PMA9000EX contains one speaker amplifier. Some units with internal speaker amplifiers, such as the King Radio KX170-series, require a resistive load to prevent damage if their speaker amplifier is not used. Connect the speaker output from the unit to the COM 2 Speaker load input on the PMA9000EX (J1 27 WRT 28). The speaker load is 16 , 3W. 2.4.
PS Engineering PMA9000EX 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 PMA9000EX 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 control the volume level of that unswitched input from 50% to 200% of the input level. Refer to Adjustments section.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.5.1 Entertainment Inputs The PMA9000EX has three music sources.

PS Engineering PMA9000EX 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 PMA9000EX, 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 sections covering the basic operating areas of the PMA9000EX systems.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual above the Com 2 transmitter pushbutton turns green. This guarantees that the pilot will always hear the audio from the transceiver selected for transmit. The PMA9000EX “remembers” the receiver selection, so that when switching transmitters from COM 1 to COM 2, if COM 2 audio was previously selected, COM 1 audio will continue to be heard.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.4 COM Audio Selector (3) Communication audio from the other radio, not selected for transmit, can be heard by pressing the associated RCV button. You will always hear the audio from the selected transceiver. In SPLIT mode, only the pilot will hear selected navigation audio. 3.5 Navaid Audio selection (4) VHF Navigation receiver audio is selected through two momentary, pushbutton, backlit switches.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual The system is designed to block continuous tones; therefore people humming or whistling in mon otone may be blocked after a few moments. For consistent performance, any headset microphone must be placed within ¼-inch of your lips, preferably against them. (ref: RTCA/DO-214, 1.3.1.1 (a)). NOTE It is also a good idea to keep the microphone out of a direct wind path.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.7.3 Intercom Modes The “ICS” pushbutton switch on the left side of the panel provides the selection of the three intercom modes. The description of the intercom mode function is valid only when the unit is not in the "Split" mode. This button cycles through the intercom modes, from left to right, then right to left as: ISO, ALL CRW and CRW, ALL, ISO.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.8.1 Speaker Amplifier The speaker (SPR) can be turned on or off in the same manner as the selected secondary navaids. This control will place all selected audio on the cockpit speaker when this switch is selected. Except for the unswitched audio, the speaker amplifier is not active in the "Split Mode”. Unswitched audio, (the inputs dedicated to autopilot disconnect, altimeter warning, etc.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.8.3 Music Source/Distribution The PMA9000EX user has two music channels, which can use any of three sources. One music channel is provided to the crew, and can be distributed to the passengers. Another music input is dedicated to the Passengers stations. The three sources, Music 1, Music 2 and MP3 can be directed via the ECAPS to the Crew and passenger channels.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.8.4 Music Volume The smaller data knob serves as the main music volume control for Music 1, and the internal MP3 play when it is playing files. In addition, the volume of the music input #2 can be adjusted independently. Hold the push button in for 2 seconds to activate the Music Volume submenu, select the source to change and use the small knob to change the volume level.
PS Engineering PMA9000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.8.5 Music Mute Control ECAPS controls the music muting allowing the user to tailor the SoftMute® to their taste and situation. There are two SoftMute muting circuits, one for pilot and copilot, and another independent circuit for the passengers. The Soft Mute circuit will cut the music almost completely out whenever there is conversation on the radio or intercom.
