PMA7000H Audio Selector Panel Marker Beacon Receiver and Stereo Intercom System Flying Never Sounded So Good™ Pilot’s Guide And Operation Manual Patent No.
OPERATION SCOPE This section provides detailed operating instructions for the PS Engineering PMA7000H 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 PMA7000H systems. They are Audio Selector, Transceiver Selection, Intercom, and Marker Beacon Receiver.
The PMA7000H 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 PMA7000H-Series has an automatic selector mode. 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 to COM 2 and watch the selected audio light on the selector change from COM 1 to COM 2.
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. NOTE: Except for the unswitched audio, the speaker amplifier is not active in the "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. 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. Then, the pilot and copilot intercom is controlled with the ICS button.
button is activated at that crew station. ICS PTT does NOT affect passenger intercom operation. Entertainment Input The audio selector panel has provisions for two separate entertainment input devices. Music 1 feeds the pilot and copilot positions, music 2 feeds the passenger positions. They operate independently in the PMA7000H. While in the ISO (Isolate) mode, the copilot will hear Entertainment 1 while the four passengers will hear Entertainment #2.
Soft Mute and Soft Mute inhibit The Soft Mute feature assures that the aircraft radio transmissions will not be missed due to entertainment playing. When there is radio reception or intercom conversation, the music level is dropped to a low, or background level. When the radio or intercom traffic ceases, the level gradually returns to normal. The front panel ICS switch controls muting of entertainment source #1 (for pilot and copilot).
Note: Because the telephone uses an intercom circuit, all stations on that circuit will lose intercom capability when the telephone is in use. Marker Beacon The Marker Beacon Receiver 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.
