PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual for units with serial number CBT1561 and above 2.4.1.1 Music Inputs and Noise PMA8000BT units utilize a differential input to help prevent noise from entering the music system. This feature is usually transparent to the installer; however, it is important that the appropriate music signal and ground connections are made directly to the dedicated music signal and ground inputs on the PMA8000BT.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual for units with serial number CBT1561 and above Some avionics do not provide a separate audio low, and may introduce additional electrical noise into the system. For best results, connect the audio low from the audio panel to the radio ground, using one conductor of the twisted-shielded cable. 2.4.5.1 Speaker Load The PMA8000BT contains one speaker amplifier.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual for units with serial number CBT1561 and above The front panel jack can be configured to act as a fifth unswitched input.

PS Engineering PMA8000BT 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 PMA8000BT, Audio Selector Panel/Marker Beacon Receiver/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 sections covering the basic operating areas of the PMA8000BT systems.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual copilot it transmitting, and the pilot presses his PTT, the pilot’s microphone will be heard over the selected com transmitter. In TEL mode, the pilot microphone and headphones are connected to the cell phone. The pilot PTT will switch the pilot mic to the selected com transceiver, and allow continued aircraft communications to continue. (See Section 3.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual Booth." Only the pilot will hear the telephone, and only he will be heard. He will also have access to Com 1 or 2, and will transmit on that radio using the PTT. All selected audio is provided to the pilot. NOTE Because the cell-phone uses an intercom circuit, all stations on that circuit will lose intercom capability when the cell phone is in use. 3.4.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.7 3.7.1 Intercom Operation IntelliVox® VOX-Squelch No adjustment of the IntelliVox® squelch control is necessary. There is no field adjustment. Through three individual signal processors, the ambient noise appearing in all six microphones is constantly being sampled. Non-voice signals are blocked. When someone speaks, only their microphone circuit opens, placing their voice on the intercom.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.7.3 Intercom Modes (8) The “ICS” pushbutton switch on the left side of the panel provides the selection of the three intercom modes. The description of the intercom mode function is valid only when the unit is not in the "Split" mode. Then, the pilot and copilot intercom is controlled with the Mute button.

If the passengers hear the radio, or talk on the intercom, the music will mute.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual NOTE Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capability when the cell phone is in use. Intercom conversations will still be present if the cell phone provides sidetone, or if the audio panel is modified for telephone sidetone. PS Engineering does not guarantee compatibility with personal cellular telephones. Visit www.ps-engineering.
PS Engineering PMA8000BT Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.11 Smart Function Keys (SFK) With Virtual Tech Support, the configuration process is self-directed. SFK annunciations are heard by the pilot and copilot positions only. SFK annunciations will be heard by the copilot, even when the audio panel is in pilot isolate mode. These annunciations will be stopped by any audio received on the com radio selected for transmit.
