Proper stripping, shielding and soldering technique must be used at all times. It is imperative that correct wire be used. Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may result in improper operation, electrical noise or unit failure.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.4 Power The PMA7000M-S-Series are compatible with both 14 and 28 Volt DC systems. A two (2) Amp circuit breaker is required for 14 VDC installations, and a three (3) Amp breaker for 28 VDC aircraft. Power and ground wires must be a twisted #18 AWG pair. Connect airframe power ground to J1 (bottom connector) Pin Z only. No dropping resistors are required. 2.4.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.10 Backlighting The PMA7000M-S 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 PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual Two stereo entertainment devices (CD player, cassette player, etc.) can be connected to the unit. Install two 1 /8-inch stereo jacks in a convenient location so that the pilot can plug in the entertainment devices into the system. The audio signal at the entertainment input must be a minimum of 500 mV P-P per channel for optimum music performance.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.19 Audio Message Acknowledge (J2, Pin W) Option 1 and 2 only) The audio message installation requires inputs from an external annunciator, such as an Electronics International engine gage system. A falling edge (input pulled low) when applied to the appropriate pin of the connector will cause the message to be played, repeating every two seconds, until the acknowledge (“ACK”) button is pushed.

PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.10 Post Installation Checkout After wiring is complete, verify power is ONLY on pin 20 of the J1 (bottom connector), and airframe ground on bottom connector pin Z. Failure to do so will cause serious internal damage and void PS Engineering's warranty. 2.11 Unit Installation To install the PMA7000M-S, gently slide the unit into the mounting rack until the hold-down screw is engaged.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.11.1.1 Marker Checkout (7000M-S only) 1. Connect a ramp generator at the antenna end of the marker coax. With the unit under test in HI sensitivity, verify that a 160 µV, modulated 95% with 1300 Hz, signal will illuminate the amber (M) marker light, and that marker audio is present in the headphones when the Marker Audio (M) push-button has been depressed.

PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual Turning the mic selector fully counterclockwise places the pilot and copilot on Com 3. Com 3 receive audio is automatically placed in the headset (and speaker if selected). Com 1 and/or Com 2 receiver audio can be selected to monitor those transceivers. The PMA7000M-S-Series has an automatic selector mode. Audio from the selected transceiver is automatically heard in the headsets and speaker.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.4.1.1 Public Address Function In PMA7000MS versions above “F” serial number for the top board (2nd set of unit serial numbers) a public address function was added. To access this function, a switch is installed to connect the top connector, pin 18, to ground. This places the pilot microphone on the speaker output (Pin W) when the PTT is pushed.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Installation and Operator’s Manual For consistent performance, any headset microphone must be placed within ¼-inch of your lips, preferably against them. (ref: RTCA/DO-214, 1.3.1.1 (a)). It is also a good idea to keep the microphone out of a direct wind path. Moving your head through a vent air stream may cause the IntelliVox® to open momentarily. This is normal.
