SPLIT COM WITH THE GMA 347
NOTE: Split COM performance is affected by the distance between the COM antennas and the separation
of the tuned frequencies. If the selected COM1 and COM2 frequencies are too close together, interference
may be heard during transmission on the other radio.
During Split COM operation, both the pilot and the copilot can transmit simultaneously over separate radios.
The pilot can still monitor NAV1, NAV2, ADF, DME, and MKR Audio as selected, but the copilot is only able
to monitor COM2.
Pressing the COM 1/2 Key selects Split COM operation. The COM 1/2 Annunciator is illuminated indicating
Split COM operation. COM1 and COM2 frequencies are displayed in green indicating that both transceivers
are active. Split COM operation is cancelled by pressing the COM 1/2 Key again, at which time the annunciator
is extinguished.
When Split COM operation is selected, COM1 is used by the pilot and COM2 is used by the copilot. The
COM1 MIC Annunciator flashes when the pilot’s microphone PTT is pressed. The COM2 MIC Annunciator
flashes when the copilot’s microphone PTT is pressed.

ENTERTAINMENT INPUTS WITH THE GMA 350
The GMA 350/350c provides three stereo telephone/entertainment inputs:
• The telephone/entertainment ( ) Key controls a telephone or entertainment device connected to the
rear of the audio panel or to the Front Panel Jack. For GSR 56 equipped aircraft, the Iridium phone audio
is connected to the rear input of the audio panel. To use the Iridium phone, ensure there is no other audio
source plugged into the Front Panel Jack.
• The MUS1 and MUS2 Key controls the Entertainment Music audio input. External audio jacks can also be
used as an entertainment input. GDL 69 (SiriusXM Radio) audio, if equipped, is wired to the MUS1 and
MUS2 inputs. The Front Panel Jack does not disable audio connected to the MUS1 and MUS2 inputs.
The Front Panel Jack can be used as an entertainment input or a telephone input. Plugging a device into the
Front Panel Jack will disable any audio source connected to the rear telephone/entertainment jack (i.e. GSR
56, if so equipped). The Front Panel Jack is a 3.5-mm stereo jack that is compatible with popular portable
entertainment devices such as MP3s, CD players, and cell phones. The headphone outputs of the entertainment
devices are plugged into the Front Panel Jack.
Distribution of the entertainment inputs are configured in Blue-Select Mode.
