Page 4: Section I - General Information
Pushbutton switches select one of the communication transceivers for the pilot and copilot position, and allows radio transmission. In "Split Mode" the PMA450 has the ability to allow the pilot to transmit on Com 1 while the copilot can transmit on Com 2. A fail-safe mode connects the pilot headphone and micro- phone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-safe) position.

The front panel USB-type connector is available for charging devices, such as iPad or cell phones. Up to 10 Watts are available. This connector does NOT provide any data interface. In the PMA450, a Bluetooth® wireless interface is available for wireless telephone and music connection. APPROVAL BASIS...

2.3 Equipment Installation Procedures 2.3.1 Cooling Requirements Forced air-cooling of the PMA450 is not required. However, the units should be kept away from heat pro- ducing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without adequate cooling air provided.
Page 9: Audio Panel Mounting Rack Installation
There must be at least 13.8 VDC present at the connect- or, J2 pins 8 & 9, of the PMA450 for the power supply to work in its designed regulation. Otherwise, it cannot adequately attenuate power line noise.
Page 10: Existing Gma340 And Pma8000 Installations
2.4.1.1 Music Inputs and Noise PMA450 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 PMA450. The power for IFE and audio panel should be a common bus.

2.4.9.1 Cell phone Sidetone The PMA450 can provide cellular telephone sidetone (the user’s voice fed back to the headset). Some cell phones provide sidetone, and may have poor audio quality if both sources are combined. The cell phone sidetone is adjustable in the Bluetooth® operation screen §2.7.
Page 13: Public Address Mode
2.4.10 Public Address Mode By holding the middle line-select pushbutton for more than one (1) seconds, the PMA450 will be placed into public address (PA) mode. In this mode, the pilot will be talking over the cockpit speaker when he presses his PTT switch.
Page 14: Playback Button Installation
Recording System playback. This switch can be located anywhere in cockpit convenient to the pilot's reach. The NO switch should be connected to pin 22 of J2 of the PMA450, and ground. When installed, this but- ton will act as in §3.12.

This allows the user to set the name of the audio panel as it will appear on devices searching for the PMA450. Seven alphanumeric digits are available. Factory default is PMA450, but you could set “N1245,” or “Skyhawk, as an example.”...
Page 17 It is probable that radio interference will occur in the split mode when the frequencies of the two air- craft radios are adjacent, and/or the antennas are physically close together. PS Engineering makes no expressed or implied warranties regarding the suitability of the PMA450 in Split Mode.
