PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual Section II -Installation 2.1 GENERAL INFORMATION 2.1.1 SCOPE This section provides detailed installation and interconnect instructions for the PS Engineering PMA6000B-Series Audio Selector Panel/Intercom System and PMA6000B-Series Audio Selector Panel/Intercom System with internal Marker Beacon. With the exception of the internal marker beacon receiver, the audio panels are identical.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 2.3.2 Mounting Requirements The PMA6000B 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 43.13-2B. The unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist. 2.3.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation 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 PMA6000B power supply is specifically designed to reduce conducted electrical noise on the aircraft power bus by at least 50dB.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual The “Mute” button can be used to inhibit the soft mute function, keeping music at the same level. In CREW mode, passengers will hear Music #2, and this will also be controlled by the “Mute” button located on the front panel. Entertainment inputs #1 and #2 can be paralleled so a single entertainment source can serve both the passengers and the crew in "crew" mode.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 2.4.4 External Push-to-Talk An important part of the installation is the PTT (Push-To-Talk) switches that allow the use of your aircraft communications radio for transmissions. There are three typical configurations that can be used. Select the case that best fits the installation. Only the person who presses their PTT switch will be heard over the radio.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual NOTE: Take precautions to prevent ESD damage prior to servicing unit 1. Remove qty. 5 Phillip head screws from the PM6000B. NOTE: THE SCREW IN THE REAR OF THE PANEL IS A DIFFERENT LENGTH THAN THE OTHER FOUR. YOU MUST PUT THE SHORTER LENGTH SCREW BACK IN THE SAME LOCATION OR DAMAGE WILL OCCUR. See Figure #1. Long shaft screws Short shaft screws Figure 2-1 Screw Locations 2.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 2.4.9 Middle Marker Sense The MM Sense output Pin 27, is connected to certain specific autopilots, and goes high only when a middle marker signal is received, not in test. 2.4.10 Unswitched Inputs The PMA6000B has two unswitched inputs. pin 7 and pin 22 are unswitched/unmated inputs that are heard by the crew and over the cockpit speaker at all times. 2.4.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 2.6 Marker Antenna Installation Refer to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2B (or later revision), Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be mounted on the bottom of the aircraft. 2.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 7. Verify that both of the Com 1 buttons light. Verify that transmit button LED (Light Emitting Diode) near the mic selector is not blinking. If the LED is blinking, stop testing and troubleshoot the microphone PTT installation. 8. Verify proper transmit and receive operation from the copilot position, noting that the copilot PTT switch allows proper transmission on the selected transceiver.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual Section III OPERATION GENERAL INFORMATION 3.1 GENERAL INFORMATION This section provides detailed operating instructions for the PS Engineering PMA6000B, Audio Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full advantage of its capabilities. This guide is divided into sections covering the basic operating areas of the PMA6000B systems.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 3.3 Volume Control (2) The volume control knob adjusts the loudness of intercom in all headphones, pilot, copilot, and passenger. It has no effect on selected radio audio or music levels. Many general aviation headsets have a built-in volume control, so volume can be reduced “locally.” 3.4 Audio Selector (3) Through the use of ten, push-button, backlit switches, it is possible to select any or all receiver audio.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual 3.5.1 Swap Mode (Switch from Com 1 to Com 2 remotely) With a yoke mounted, momentary switch, the pilot can change from the current Com transceiver to the other by depressing this switch. When "Swap Mode" is active, the COM transmit and receive indicators will toggle to the other Com. To cancel "Swap Mode," the pilot may either press the yoke mounted switch again, or push the other com selector. 3.5.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual meet the situation. The description of the intercom mode function is valid only when the unit is either in the COM 1 or COM 2 modes. When the unit is in the "Split" mode, only the passengers have intercom function. Pushing the ICS button cycles the intercom through the three intercom modes. ISO: (Top indicator): The pilot is isolated from the intercom and is connected only to the aircraft radio.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual The White lamp, labeled "I” is the Airway/Inner marker and has a 3000 Hertz 'dot' tone. The lamp and tone will be keyed at a rate of six times per second. The audio from the Marker Beacon Receiver can be heard by selecting the "M" push-button switch. A 3-position switch is used to set the receiver sensitivity and to test the indicator lamps. Use "HIGH" sensitivity initially.
PS Engineering PMA6000B Audio Selector Panel and Intercom System Installation Manual Section IV- Warranty and Service 4.1 Warranty In order for the factory warranty to be valid, the installations in a certified aircraft must be accomplished by an FAA- certified avionics shop and authorized PS Engineering dealer. If the unit is being installed by in an experimental aircraft by the owner/builder, a factory-made harness must be installed for the warranty to be valid. PS Engineering, Inc.
