OPERATION SCOPE This section provides detailed operating instructions for the PS Engineering PMA7000H 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 PMA7000H systems.
The PMA7000H 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 PMA7000H-Series has an automatic selector mode. Audio from the selected transceiver is automatically heard in the headsets and speaker (if selected).
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. PS Engineering makes no warranty about of Split Mode in all aircraft conditions. the suitability Note: Split Mode does not turn off other (Nav, ADF, etc.) selected...
This is normal, for best performance, go fly! For optimum microphone performance, PS Engineering recommends in- stallation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but will improve the overall clarity of all your communications.
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.
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 in- put devices. Music 1 feeds the pilot and copilot positions, music 2 feeds the passenger positions.
The Com 3 input can serve as a full duplex interface for telephone systems if the installation is correctly configured. Visit www.ps-engineering.com for a list of compatible systems. PS Engineering does not guarantee com- patibility with all cellular or wireless telephone products.
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.
