OPERATION GENERAL INFORMATION SCOPE This section provides detailed operating instructions for the PS Engineering PMA6000C, and PMA6000M-C, Audio Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This guide is divided into four sections covering the basic operating areas of the PMA6000 systems. They are: Audio Selector, Audio Selection, Intercom, and Marker Beacon Receiver (PMA6000M-C only).
beled Nl (Nav 1), N2 (Nav 2), D (DME), M (Marker), A (ADF), AX (auxiliary), and S (Speaker) are "latched" type switches. When one of these buttons is pressed, it will stay in the "in" position. Press the switch again and it will be in the "out" position and remove that receiver from the audio. While selected, the switch will also be annunciated by an internal lamp. NOTE: In Split Mode, no pushbuttons will be active. The only audio selected is from Com 1 and Com 2, as indicated by their respective lamps.
(PTT), will be heard over the aircraft radio. Turning the rotary switch to the COM 2 position will place pilot and copilot on Com 2. The PMA6000-Series has an automatic selector mode. Audio from the selected transceiver is automatically heard in the headsets and speaker (when selected). You can check this function by switching from COM 1 to COM 2 and watch the selected audio light on the selector change from C1 to C2. This ensures the pilot will never transmit on a radio that he is not listening to.
Split Mode Turning the rotary switch to COM 1/2 puts the PMA6000 into "Split Mode". This places the pilot on Com 1 and the copilot on Com 2. Pilot and copilot are isolated from each other and do not have intercom capability, but can use their respective radios simultaneously. An example of this useful feature is when the pilot may want to talk to Air Traffic Control, while the copilot may be speaking to Flight Watch. The "Split Mode" radio selection can be reversed by switching to COM 2/COM l.
copilot volume control adjusts the loudness of the intercom and music in the copilot headset only. The passenger volume is factory set at a comfortable level. This is a service adjustment that can be accessed by the avionics technician. Many general aviation headsets have a built-in volume control, so volume can be reduced “locally.
rotating the SQL control knob clockwise until you no longer hear the engine noise in the headphones. When the microphone is positioned properly near your lips, normal speech levels should open the channel. When you have stopped talking, there is a delay of about ½ second before the channel closes. This helps prevent choppy communications. Some PMA6000 installations may include an intercom Pushto-talk button, located n a yoke or stick.
rupting the Crew and also may listen to Entertainment 2. Anytime the PMA6000 is in either the COM 1/COM 2, COM 2/COM 1, or TEL/COM 1, ("Split Mode") the pilot and copilot do not have any intercom function. The passengers will maintain intercommunications. Soft Mute Soft Mute must be enabled during installation by jumpering top connector pins 12 and N. A SPST switch can be installed between these pins for a pilot selectable mute mode. Without this connection, music is not muted during intercom activation.
Internal Recorder System (Option 1, only) The recorder function is automatic. Pressing the momentary switch will cause the last message to play (incoming radio and transmit sidetone). This will be heard in the pilot headset only. To hear older messages, push the playback button repeatedly to “back up” the recorder, until the desired message is heard. The recorder is a continuous loop, and newest ones will overwrite the oldest messages. The IRS has an internal squelch that prevents storing ‘dead’ air.
This allows you to hear the outer marker beacon about a mile out. Then select the “LOW” sensitivity to give you a more accurate location of the Outer Marker. The momentary down switch position is labeled "TEST" and illuminates all three lamps simultaneously to assure the lamps are in working order. Early PMA6000M units incorporated a Marker Self Test. Upon first application of power to the unit, the Marker enters a self test mode. The flickering blue marker light indicates a test in process.
Factory Service The unit is covered by a 1-year limited warranty. See warranty information. Contact PS Engineering, Inc. at (865) 988-9800 or www.ps-engineering.com/support.shtml before you return the unit. This will allow the service technician to provide any other suggestions for identifying the problem and recommend possible solutions. After discussing the problem with the technician and you obtain a Return Authorization (RMA), ship product to: Service Department PS Engineering, Inc.
