PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual Section II - Installation 2.1 GENERAL INFORMATION 2.1.1 SCOPE This section provides detailed installation and interconnection instructions for the PS Engineering PMA7000B-Series Audio Selector Panel/Intercom/ with internal Marker Beacon. Please read this manual carefully before beginning any installation to prevent damage and postinstallation problems.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual FHP 6-32 x ½" screws (475-632-0012). The audio selector panel must be supported at front and rear of the mounting tray. 2.3.4 Audio Panel Tray and Connector Assembly The unit connectors mate directly with the circuit boards in the PMA7000B. The connectors are a Molex crimp-type, and require the use of a Molex hand crimp tool, EDP P/N 11-01-0203, CR6115B (or equiv.).
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual NOTE: PS Engineering can make a custom wiring harness for the intercom. Call 1-800-ICS-AERO or see www.ps-engineering.com for details. 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.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.4 Power The PMA7000B-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 PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual inactive, and audio from Com 3 is presented to the headset. This allows a telephone-like audio interface. The COM 3 input and output are compatible with aviation radios. The COM 3 input and output are compatible with general aviation radios. However, if J2, Pin J is connected to aircraft ground (either directly or through a switch), the PMA7000B is forced into Com 3Duplex mode.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.11 Unswitched inputs J1, pins T, 17, U and X are unswitched, unmuted inputs. These inputs are presented to the pilot and copilot regardless of the audio configuration, and will always mute the entertainment inputs. These 510 Ω inputs can be used for altimeter DH audio, GPS waypoint audio, autopilot disconnect tones, or any other critical audio signal.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.4.16 Entertainment Input The PMA7000B has two INDEPENDENT music inputs. Entertainment input number 1 is J2 pins 15 (left channel) and 16 (right channel), WRT pin T, and is provided to the pilot and copilot. Entertainment number 2 is provided to the passengers at all times. Entertainment 1 and 2 must be connected together in order for all positions to hear the same music source.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual Interface to the expansion unit is through J2, pins P (audio input from expansion unit), S (audio output to expansion unit) and C (9 VDC expansion power). 2.5 Marker Beacon Installation The marker beacon receiver is an option included in the PMA7000B. Non-marker (PMA7000) units can provide audio interface with the external receiver (see section 2.5.4). 2.5.

PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.9 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. 2.10 Unit Installation To install the PMA7000B, gently slide the unit into the mounting rack until the hold-down screw is engaged.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual pilot has radio transmit capability in Com3 duplex mode, on the selected Com ( 1 or 2). However, he will have Com 3 capability if the copilot hook switch is grounded. 13. Verify proper operation of all receiver sources by selecting them using the appropriate button. The button illuminates to show which source is in use. 14. Push the SPR button.
PS Engineering PMA7000B 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 PMA7000B, 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 PMA7000B systems.
PS Engineering PMA7000B Audio Selector Panel and Intercom System Installation and Operator’s Manual 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. When the duplex enable, or TELEPHONE mode is implemented during installation, Com 3 becomes the “TEL” position.
PS Engineering PMA7000B 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.
