PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual Section II - INSTALLATION 2.1 2.1.1 GENERAL INFORMATION SCOPE This section provides detailed installation and interconnectio n instructions for the PS Engineering PMA5000EX Audio Selector Panel/Intercom. Please read this manual carefully before beginning any installation to prevent damage and post installation problems.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual mounting block, 431-891-0100. Ensure that proper strain relief and chafing precautions are made during wiring and installation, using the cable clamp (625-001-0002). Two grounding lugs are provided, which may be attached to the rear mounting plate with 2 ea #4 -40 x ¼” screws with captivated lock washers. These provide a convenient location to connect the shield ground terminations.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual and ground connections are made directly to the dedicated music signal and grou nd inputs on the PMA5000EX. The power for IFE and audio panel should be a common bus. If a music jack instead of a music source is installed for Music 1 or 2, we recommend grounding the jack to airframe ground.

Unswitched #1 is always presented to the to the crew headphones, and is available to the pilot in fail -safe (off) mode. Unswitched 3 and 4 inputs are always presented to the crew headphones.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.5.2 Entertainment muting The PMA5000EX-system incorporates a "Soft Mute™" system. This will mute the entertainment devices during ICS or radio conversation. See Section 3.7 for more information. Any signal appearing in the hard wired unswitched audio inputs will always mute the entertainment sources, even though the passengers may not hear the audio tone itself.

PS Engineering PMA5000EX 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 pins 8 and 9 of the J2 and airframe ground on J2 connector pins 10 and 11. Failure to do so will cause serious internal damage and void PS Engineering's warranty. 2.10 Unit Installation To install the PMA5000EX, gently slide the unit into the mounting rack until the hold -down screw is engaged.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.11.2 TEL Checkout Press the TEL button. Verify that the pilot headset is connected to the cellular telephone system (if i nstalled). Verify that by using the pilot side PTT, the pilot can transmit on the other selected radio (Com 1 or Com 2). The telephone function will allow any person heard by the pilot on the intercom, also heard on the telephone. 2.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual Section III OPERATION 3.1 SCOPE This section provides detailed operating instructions for the PS Engineering PMA5000EX, Audio Selector Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full a dvantage of its capabilities. This section is divided into sections covering the basic operating areas of the PMA5000EX systems.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual the pilot having to switch Com 1 audio back on, after changing transmitters. When switching from COM 1 to COM 2 while Com 2 was not previously selected, COM 1 audio will be switched off. In essence, switching the mic selector will not override prior selection of COM receiver audio. In normal (not split) modes, the PMA5000EX gives priority to the pilot’s radio Push-To-Talk (PTT).

When one of these buttons is pressed, the mode is active, and the LED will illuminate. Press the switch again and it will be "off" and remove that receiver from the a udio output. In SPLIT mode, only the pilot will hear selected navigation audio. 3.

PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.7 Music Muting (6) There are two SoftMute™ muting circuits. The front panel "Mute" button has four modes, and controls the Mute function for music 1. Music 2 muting is controlled by an external switch, and has two modes. The SoftMute™ circuit will cut the music out whenever there is conversation on the radio, the intercom, or both, depending on the “Mute” mode selected.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual The volume changes about three steps per second, so it takes about 10 seconds to ramp the volume across the full range. It is possible to turn the volume completely off, so try pressing the volume up button if you don’t hear music as expected. 3.9 Telephone Mode (9) The TEL mode serves as a full duplex interface for compatible telephone systems such as portable cellular phones with earpiece jacks.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.10.2.1 Smart Jack Function When the PMA5000EX has a signal on music #1 input coming in from the rear connector, the front panel jack automatically becomes a Priority Advisory input, and is heard in the crew headphones. NOTE The front jack is no substitute for the installation of alerts such as the GPS waypoint or autopilot tones. These still must be hard wired into the back by your installer. 3.10.
PS Engineering PMA5000EX Audio Selector Panel and Intercom System Installation and Operator’s Manual When the music is standard, Music 1 will always go to the pilot and copilot positions, and is never heard by the passengers. Music 2 is always heard by the passengers, and never heard by the pilot and copilot. This mode is useful if your passengers have a different interest in entertainment or are watching a DVD, but do not want to be excluded from the intercom conversations. 3.10.
