Page 2: Power Switch (Emg-Fail Safe Operation)
OPERATION SCOPE This section provides detailed operating instructions for the PS Engineering PMA7000B Audio Selector Panel/Intercom Systems. Please read it care- fully 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.
Page 3: Swap Mode (Switch From Com 1 To Com 2 Remotely)
The lower buttons control which transceiver is selected for transmit. The PMA7000B gives priority to the pilot’s PTT. If the copilot it transmit- ting, 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.
Page 4: Speaker Amplifier
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 acti- vated. 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 but- ton position.
Page 5: Intercom Volume Control
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.
Page 6: Intercom Modes
lose one channel, unless they switch to the “MONO” mode on the headset. PS Engineering modifies headsets to add stereo capability, using high- fidelity 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.
Page 7 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 listen- ing level when the intercom or radio conversation ceases. It is also possible to use a single input device for both entertainment inputs.
Page 8: Telephone Mode
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.
Page 9: Marker Beacon
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 associ- ated 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.
Page 10: Warranty
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 factory- made intercom harness must be used for the warranty to be valid.
