Page 9: Cable Harness Wiring
There must be at least 13.8 VDC present at the connect- or, J2 pins 8 & 9, of the PMA8000C for the power supply to work in its designed regulation. Otherwise, it cannot adequately attenuate power line noise.
Page 10: Existing Gma340 Installation
2.4.3 Power The PMA8000C is compatible with both 14 and 28 Volt DC systems. A five (5) Amp circuit breaker is required for all installations. Power and ground wires should be #22 connected to J2 Pins 8 and 9. Connect airframe ground to J2 Pin 10 and 11 only.

Therefore, it may not recognize speech and clip syllables in a quiet cabin, such as in the hangar, or without the engine running. This is normal. For optimum microphone performance, PS Engineering recommends installation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but will improve the overall clarity of all your communications.

Crew and may listen to entertainment as configured. 3.8 Music Distribution and Music Muting (6) The PMA8000C has two independent music inputs at the rear connector, and a front panel jack. The PMA8000C also has the ability to receive streaming music from a Bluetooth-enabled device.

Page 29: Smart Function Keys (Sfk)
3.9.1.1 Smart Jack Function When the PMA8000C 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 certified installation of alerts such as the GPS waypoint or autopilot tones.
Page 30: Music Function (C) (Music Distribution Control)
Function “C” controls how music is distributed in your airplane. There are multiple music sources available to the PMA8000C. Music 1 input can be streamed from a Blue- tooth source, input through the front jack, OR the Music 1 input at the rear connector (Pins 23 and 24 J2).
Page 31: Music 1 Volume
In general, we recommend adjusting the entertainment volume at the sources, and only using this as a mas- ter gain control. However, the Music 1 PMA8000C input can be adjusted from the front panel, if desired, by pressing the combinations of keys listed.
Page 32: Luetooth Interface
The device eliminate will be selected at ran- dom by the Bluetooth module. Hint, if your old phone is not recognized by the PMA8000C, you may simply need to re-pair.
Page 33: Power On Announcement
In ISO intercom mode, when the PMA8000C is in the TEL mode, the pilot position is in the "Phone 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.
