Microphone Gain Selection
In very high noise environments (such as open cockpit, etc.) the PMA5000EX can be switched to a lower
microphone gain by configuring internal switches.
Contact PS Engineering
for more information.
2.7 Communications Antenna Installation Notes
For best results while in Split Mode, it is recommended that the one VHF communications antenna is locat-
ed on top of the aircraft while the other communications antenna is installed on the bottom. Any antenna
relocation should be accomplished in accordance with AC 43.13-2B, and /or aircraft manufacturers’ rec-
ommendations.
WARNING
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 PMA5000EX in Split Mode.
