9800 Martel Road Lenoir City, TN 37772 www.ps-engineering.com PMA8000B Audio Selector Panel Marker Beacon Receiver High-fidelity Stereo Intercom System Pilot’s Guide and Operation Manual 202-890-0202 Revision 6 June 2008 Covered under one or more of the following Patent No.
This pilot guide provides detailed operating instructions for the PS Engineering PMA8000B, Audio Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This publication covers the basic operating areas of the PMA8000B systems. They are Com Transceiver Selection, Audio Selector, Intercom, and Marker Beacon Receiver, utility jack and the configuration buttons.
The PMA8000B-Series has an automatic selector system. Audio from the selected transceiver is automatically heard in the headsets and speaker (if selected). You can check this function by switching from COM 1 transmitter to Com 2 transmitter by pressing the COM 2 transmitter selector pushbutton. Note that the associated Com 2 receive pushbutton indicator light that is located immediately above the Com 2 transmitter pushbutton turns green.
Note: Split Mode does not turn off Nav, ADF, or Aux selected audio to pilot. However, the copilot will only hear the selected com receiver and unswitched inputs. Swap Mode (Switch from Com 1 to Com 2 remotely) With a yoke mounted, momentary switch, the pilot can change from the current Com transceiver to the other by depressing this switch. To cancel "Swap Mode," the pilot may either press the yoke mounted switch again, or select a different Com with the XMT buttons.
The telephone party will not hear ATC communications, 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.
Intercom Operation IntelliVox® VOX-Squelch No adjustment of the IntelliVox® squelch control is necessary. There is no field adjustment. Through three individual signal processors, the ambient noise appearing in all six microphones is constantly being sampled. Non-voice signals are blocked. When someone speaks, only their microphone circuit opens, placing their voice on the intercom.
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. The IntelliVox® is designed to work with normal aircraft cabin noise levels (70 dB and above). Therefore, it may not always recognize speech and clip syllables in a quiet cabin, such as in the hangar, or without the engine running. This is also normal.
This button cycles through the intercom modes, from top to bottom and then back up, ISO, ALL, Crew, ALL, and ISO. An LED shows the active mode . ISO: The pilot is isolated from the intercom and is connected only to the aircraft radio system. He will hear the aircraft radio reception (and sidetone during radio transmissions). The copilot and passengers will hear the music sources as configured by the audio panel configuration Function keys. See page 11—Smart Function Keys for more details.
A pushbutton is used to set the receiver sensitivity and to test the indicator lamps mute the marker audio. Use "HI" sensitivity initially. This allows you to hear the 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.
Utility Jack The 2.5 millimeter (3/32”) jack on the front of the PMA8000B has three distinct functions: • Cell phone input • Advisory audio input • Music input The use of this jack is controlled by three Smart Function Keys (SFK) controlled from the front panel. See Page 11—Smart Function Keys. Cellular phone When a cellular telephone is connected to this jack using a 2.5 mm to 2.
jack automatically becomes a Priority Advisory input, and is heard in the crew headphones. This input will NOT be muted by radio or intercom. Music Input When used as a music input, the front panel jack is treated as Music #1. However, thanks to the function controls, it can be distributed to all users, regardless of the intercom mode. Smart Function Keys (SFK) With Virtual Tech Support, the configuration process is self-directed.
There are three special functions. Function Button “A” is related to the intercom function, and allows the crew to mute passengers’ intercom feed when radios are active. Function Buttons “B” and “C” control how music is distributed in your airplane.
Function “B” Function Button “B” allows you to either send the music 1 input to all intercom stations, all of the time, or have the normal rules apply to our music inputs. When “Music number one distribution, all headsets” is selected, music 1 (or the front panel utility jack) 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.

mute for incoming radio or intercom conversation. The passenger’s intercom also has a SoftMute™ circuit. It behaves the same way as the crew; if the passengers will hear the radio, or talk on the intercom, the music will mute. If the audio panel is in CREW mode, then the radio reception will not affect the passenger music. Passengers also have a Karaoke Mode. If the passengers are listening to the music 1 input or front panel input, their Karaoke Mode is controlled by the front panel button labeled "Mute".
