PMA7000B-Series Audio Selector Panel Marker Beacon Receiver and Stereo Intercom System Flying Never Sounded So Good™ Pilot’s Guide And Operation Manual Patent Nos.
OPERATION SCOPE This section provides detailed operating instructions for the PS Engineering PMA7000B Audio Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This chapter is divided into four sections covering the basic operating areas of the PMA7000B systems. They are Audio Selector, Transceiver Selection, Intercom, and Marker Beacon Receiver.
The lower buttons control which transceiver is selected for transmit. The PMA7000B gives priority to the pilot’s PTT. If the copilot it transmitting, and the pilot presses his PTT, the pilot’s microphone will be heard over the selected com transmitter. The PMA7000B-Series has an automatic selector mode. Audio from the selected transceiver is automatically heard in the headsets and speaker (if selected).
Speaker Amplifier The "SPR" in the push-button section stands for speaker. This switch will place all selected audio on the cockpit speaker when this switch is activated. The speaker amplifier will present the audio sources selected by the pilot, in “Split Mode." Unswitched audio, (autopilot disconnect, altimeter warning, etc.) will come through the speaker regardless of the speaker button position. Public Address Function To access PA function, an external switch must be installed, and activated.
Intercom Operation IntelliVox® VOX-Squelch No adjustment of the IntelliVox® squelch control is necessary. There is no field adjustment. Through 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.
lose one channel, unless they switch to the “MONO” mode on the headset. PS Engineering modifies headsets to add stereo capability, using highfidelity speakers. Contact factory for details. Intercom Modes The lower switch on the left side is a 3-position mode switch that allows the pilot to tailor the intercom function to best meet the current cockpit situation. The description of the intercom mode function is valid only when the unit is not in the "Split" mode.
while the four passengers will hear Entertainment #2. In normal operation, whenever a person speaks, or if the aircraft radio becomes active, the music will automatically mute and then will gradually return to the original listening level when the intercom or radio conversation ceases. It is also possible to use a single input device for both entertainment inputs. However, we suggest that a switch (DPDT) be installed between the entertainment device and entertainment input #1.
The front panel ICS switch controls muting of entertainment source #1 (for pilot and copilot). Pushing this button places the ICS in Karaoke (or sing along) mode, which inhibits the soft mute feature. This allows the music to continue uninterrupted by intercom or radio traffic when cockpit workload is appropriate. Pushing the button again will release the mute inhibit function. The passenger music, source #2, can be placed in the Karaoke mode if a remote switch is installed in the aircraft.
Marker Beacon The Marker Beacon Receiver (if equipped) uses visual and audio indicators to alert you when the aircraft passes over a 75 MHz transmitter. The Blue lamp, labeled "O," is the Outer Marker lamp and has an associated 400-Hertz 'dash' tone. The lamp and tone will be keyed at a rate of two tones/flashes per second when the aircraft is in the range of the Outer Marker Beacon. The Amber lamp, labeled "M," is the Middle Marker lamp and is coupled with a 1300-Hertz tone.
Warranty 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 factorymade intercom harness must be used for the warranty to be valid. PS Engineering, Inc.
