9800 Martel Road Lenoir City, TN 37772 www.ps-engineering.com PMA8000B Audio Selector Panel Marker Beacon Receiver Stereo Intercom System Flying Never Sounded So Good! ® Pilot’s Guide and Operation Manual 202-890-0202 Rev. 12 May 2012 Covered under one or more of the following Patent No.
This pilots guide provides operating instructions for the PMA8000B Audio Panel. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This guide is divided into operating sections such as Transceiver Selection, Audio Selector, Intercom, and Marker Beacon Receiver, and special functions. The center section provides a handy reference that you can remove.
Unless the audio panel is in “split” mode, the PMA8000B gives priority to the pilot’s radio Push-To-Talk (PTT). If the Monitor function is activated, the audio from this radio will be muted when the primary radio (selected for transmit) is receiving a signal. In TEL mode, the pilot is connected to the cell phone, but still hears the COM radios selected. The radio PTT will switch the mic to the selected com, and allow continued aircraft communications to continue.
and not twisted inside the cover. Note: For optimum microphone performance, we recommend use of a Microphone Muff Kit from Oregon Aero (1-800-888-6910, www.oregonaero.com ). This will not only optimize VOX performance, but will improve the overall clarity of all your communications. You should also keep the microphone out of a direct wind. Moving your head through an air stream may cause the IntelliVox® to open momentarily. This is normal.
ALL: All parties will hear the aircraft radio and intercom. Crew will hear Music 1, passengers can hear Music 1 or 2. The music mutes in accordance with the muting mode selected. CRW: (Crew) Pilot and copilot are connected on one intercom channel and have exclusive access to the aircraft radios. The passengers have their own intercom. The music that the crew and passengers will hear is determined by the Smart Function Keys.
Select either of the com XMT buttons to exit the split mode. It is not possible to have the pilot on Com 2 and copilot on COM 1 in split mode. In the split mode, the intercom is disabled, and the MUTE indicator is on. Push MUTE to enable the intercom if desired. NO T E: Due to the nature of VHF communications signals, and the size constraints in general aviation aircraft, it is probable that there will be some bleed-over in the Split mode, particularly on adjacent frequencies.
Quick reference PMA8000B Operation This pull-out section covers advanced operation of the PMA8000B. Split Mode The Split mode puts the pilot on COM 1, while the copilot can use COM 2 independently. To enter the split mode, press both the COM 1 and COM 2 XMT buttons at the same time. To exit, press the desired COM 1 or COM 2 XMT button. When you activate the Split mode, the intercom is inhibited to avoid confusion with multiple conversations. reactivate the intercom, press the Mute button.
Music Muting Music source #1 (front panel jack and Music 1 input) has four muting modes, which are announced in the headset as they are activated. These are: Radio Mute (aircraft radio mutes music), Intercom Mute (intercom conversation mutes music), Mute on (both radio and intercom mutes music), and Mute off (nothing interrupts music). Press the Mute button to cycle through the modes in sequence. Music #2 has muting on or off, and is externally controlled.

“Smart” Front Panel Jack When music 1 is actively playing through the rear panel input, the front jack automatically becomes an advisory audio input, and is NOT muted by radio or intercom conversations. This is useful for connecting portable traffic or terrain alert devices. If Music 1 is not active, the mute mode should be deselected. Recorder Playback The internal recorder is always storing the audio from the radio selected for transmit.
(Continued from page 6) Cellular phone When a cellular telephone is connected to this jack using an adapter cord (PS Part Number 425-006-7026), the PMA8000B audio panel will connect the intercom to the cell phone when the “TEL” button is pressed (9). When the TEL mode is off, the telephone ringer audio will be heard if it is present on the telephone’s output (ringer may be muted by radio and intercom).
The “Monitor” function mutes the secondary communication radio audio when the primary radio (the one selected to transmission) is active. “Music” function controls how music is distributed in your airplane. There are two music sources available to the PMA8000B, Music 1 input can be either on the front jack, or the Music 1 input at the rear connector (Pins 23 and 24, J2).
When “Music number one, all headsets” is selected, Music 1 from the rear connector) 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, although though they will not hear the crew intercom or radios. This mode allows you to use a single in-flight entertainment source. The music muting follow the selected mode of the crew and passengers.
• Radio Mute - Radio will mute music, but intercom will not mute music - MUTE LED is OFF. Annunciation is "Radio mute." • Intercom Mute - Radio will not mute music, intercom will mute music - MUTE LED is OFF. Annunciation is "Intercom mute." • Mute Off - The “Karaoke” mode - music will not mute except during radio transmissions.- MUTE button LED is OFF. Annunciation is "Mute off." When the PMA8000B is turned on, it always begins in “Mute on” mode. The passengers’ intercom also has a SoftMute™ circuit.
Internal Recorder System The Intercom Recording System is a continuous loop recorder, (last message received will be the first heard), the recorder has 45 seconds of recording time, or up to eight messages. There are no buttons to press to start recording. The system automatically begins to record the instant the radio selected for transmit becomes active. Only the pilot and copilot will hear the playback audio.
Warranty & Service In order for the factory warranty to be valid, the installations in a certified aircraft must be accomplished by an FAA-(or other ICAO agency) certified avionics shop and authorized PS Engineering dealer. If the unit is being installed by a non-certified individual in an experimental aircraft, a factory-made intercom harness must be used for the warranty to be valid. PS Engineering, Inc.
