PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual 2.3.2 Mounting Requirements The PMA6000 must be rigidly mounted to the instrument panel of the aircraft structure and within view and reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2A. The unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual ference is possible. The PMA6000s were designed in a RFI hardened chassis and have internal Electromagnetic Interference (EMI) filters on all inputs and outputs. Ground loop noise occurs when there are two or more ground paths for the same signal (i.e., airframe and ground return wire). Large cyclic loads such as strobes, inverters, etc.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual the single entertainment device and entertainment input #1. This will allow the pilot and copilot to decide if they hear entertainment while in the Crew mode. Local oscillators and internal signals from some entertainment equipment can cause undesired interference with other aircraft systems. Before takeoff, operate the entertainment devices to determine if there is any adverse effect within the aircraft systems.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual NOTICE: To reduce the amount of heat dissipated in the audio selector panel, when used in a 28 Volt aircraft, a 15 Ω, 15 Watt dropping resistor (p/n 701-015-1501) must be installed in series with the power input. 2.4.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual Bottom connector pin T is an unswitched and unmuted audio input. This audio is always presented to the headphones and speaker, regardless of the audio panel audio selections. This input can be use for critical warnings, such as radio altimeter warnings. 2.4.13 Intercom The top connector is for the intercom function.

With the unit under test in HI sensitivity, verify that a 150 µVolts, 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) pushbutton has been depressed.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual 2.11 Final Inspection. Verify that the wiring is bundled away from all controls and no part of the installation interferes with aircraft control operation. Move all controls through their full range while examining the installation to see that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accordance with good practices, with adequate strain relief.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual Section III OPERATION GENERAL INFORMATION 3.1 SCOPE This section provides detailed operating instructions for the PS Engineering PMA6000, PMA6000S, PMA6000M, PMA6000M-S, PMA6000C, PMA6000S-C, PMA6000M-C, and PMA6000M-S-C Audio Selector Panel/Intercom Systems.

PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual 3.3 Mic Selector Switch (Fail Safe Operation) Figure 3-2 Mic Selector Unit power is turned on and off by the Mic selector switch. In the OFF or "FAILSAFE" position, the pilot is connected directly to Com 1 allowing transmit and receive capability regardless of unit condition. Any time power is removed or turned OFF, the audio selector will be placed in the fail-safe mode.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual 3.5 Split Mode (6000C, 6000MC, 6000SC, 6000MSC) Operation is identical to section 3.4 (above) except turning the mic selector clockwise to the COM 3 position places both pilot and copilot on Com 3, and exits the split mode. All selected audio inputs and intercom function return. Note: In all PMA6000s, Split Mode turns off all other (Nav, ADF, etc.)selected audio to pilot and copilot.

The user can adjust the trip level of the VOX to fit the individual's voice and mic, which helps eliminate the frustration of clipping the first syllables. With the engine running, set the VOX control knob by slowly rotating the SQL control knob clockwise until you no longer hear the engine noise in the headphones.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual 3.6.5.3 Entertainment Input The audio selector panel has provisions for up to two separate entertainment input devices. Which device is heard is determined by the position of the three position mode switch located in the center of the intercom section of the audio panel. (See Table 3-1 for overview.) While in the ISO (Isolate) mode, only the copilot and the four passengers will hear entertainment device #1.
PS Engineering PMA6000 Series Audio Selector Panel and Intercom System Installation Manual The recorder function is automatic. Pressing the momentary switch will cause the last message to play (incoming radio and transmit sidetone). This will be heard in the pilot headset only. To hear older messages, push the playback button repeatedly to “back up” the recorder, until the desired message is heard. The recorder is a continuous loop, and newest ones will overwrite the oldest messages.
