PS Engineering PMA7000H Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.1 Noise Due to the variety and the high power of radio equipment often found in today's general aviation aircraft, there is a potential for both radiated and conducted noise interference. The PMA7000H power supply is specifically designed to reduce conducted electrical noise on the aircraft power bus by at least 50dB.
PS Engineering PMA7000H Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.3.3 Speaker Load The PMA7000H contains a speaker amplifier. Some units with internal speaker amplifiers, such as the King Radio KX170, require a resistive load to prevent damage if their speaker amplifier is not used. Connect the speaker output from the unit to the load input on the PMA7000H (J1, pins 19 and L, 16 and M.) The speaker load is 16 , 3W. 2.4.
PS Engineering PMA7000H Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.7 Backlighting The PMA7000H has an automatic dimming of the pushbutton annunciator LEDs and marker lamps controlled by a photocell. Control of the unit backlighting is through the aircraft avionics dimmer. Connect the dimmer control line to J1 pin D for 14-volt systems, and to J1 pin F for 28-volt systems. Pin E is light ground.
PS Engineering PMA7000H Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.13.1 Intercom Microphone Wiring The PMA7000H is a 9-place intercom system; supporting seven passengers. Passengers 1 through 4 have individual mic audio high and low connections on J2. Passengers 5, 6 and 7 have mic audio high inputs, however the mic audio low connections are combined with Passenger 4 mic, on J2, Pin H. See Appendix D. 2.4.13.

PS Engineering PMA7000H Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.11 Cellular Interface Checkout When a wireless telecommunication system is installed and the unit configured for duplex, a dial tone will appear in the headset of the pilot when the COM 3 Xmt selector activated. In “ALL” intercom mode, a dial tone will be heard whenever the copilot or passenger’s hook switch is closed. 2.
PS Engineering PMA7000H Audio Selector Panel and Intercom System Installation and Operator’s Manual Section III OPERATION GENERAL INFORMATION 3.1 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 section is divided into four sections covering the basic operating areas of the PMA7000H systems.
PS Engineering PMA7000H Audio Selector Panel and Intercom System Installation and Operator’s Manual When switching from COM 1 to COM 2, while COM 2 audio had been selected, Com 1 audio will continue to be heard. This eliminates the pilot having to switch Com 1 audio back on, if desired. When switching from COM 1 to COM 2 while Com 2 has NOT been selected, Com 1 audio will be switched off. In essence, switching the mic selector will not effect the selection of Com receiver audio.
PS Engineering PMA7000H Audio Selector Panel and Intercom System Installation and Operator’s Manual Note: Due to the nature of 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 the suitability of Split Mode in all aircraft conditions. Note: Split Mode does not turn off other (Nav, ADF, etc.) selected audio to pilot.
