Garmin G1000 Audio Panel Pilot's Guide 190-00378-02 Rev. A INTRODUCTION 6A. 1 INTRODUCTION This manual provides the pilot with a description of the GMA 1347 and its operating instructions. The Garmin GMA 1347 is an audio control panel and marker beacon system. Pressing the audio panel keys controls audio selection of COM, NAV, telephone and intercom. [. . . ] The marker indicators are located to the left of the Altimeter on the PFD (Figure 6A. 3. 3). The outer marker frequency is 400 Hz with a blue indicator, the middle marker frequency is 1, 300 Hz with an amber indicator and the inner marker frequency is 3, 000 Hz with a white indicator. Refer to Table 6A. 3. 1 for a summary of the marker beacon signal characteristics. When the MKR/MUTE key is selected, the annunciator light illuminates and the audio signal can be heard over the speaker or headsets during marker reception. Marker Beacon Signal Sensitivity The HI SENS key can be pressed for increased marker beacon signal sensitivity. The HI SENS function is used to receive an earlier indication of nearing a marker during an approach. Figure 6A. 3. 2 Marker Beacon 190-00378-02 Rev.

A OPERATION NAVIGATION RADIOS Pressing DME, ADF, AUX, NAV1, or NAV2 selects and deselects the radio source and activates the annunciator. Selected audio can be heard over the headset and the speakers. All radio keys can be selected individually or together. MUSIC 1 MUSIC 1 can be heard by the pilot in COPILOT mode and in ALL mode, and can be heard by the copilot in PILOT mode and in ALL mode. In PILOT mode, the pilot can hear the selected radios, the copilot can hear MUSIC 1, the passengers can hear MUSIC 2, and the copilot and passengers can communicate with each other. ALL Mode ALL mode is selected when the PILOT and the COPLT keys are not annunciated. In ALL mode, everyone hears the selected radios and is able to communicate with everyone else. In this mode, both the pilot and copilot can hear MUSIC 1, while the passengers hear MUSIC 2. COPILOT Mode COPILOT mode is selected when only the COPLT key is annunciated. In COPILOT mode, the copilot is isolated from everyone else. The pilot and passengers can hear the selected radios and communicate with each other. In this mode, the pilot can hear MUSIC 1, while the passengers can hear MUSIC 2.

A Garmin G1000 Audio Panel Pilot's Guide 6A-11 OPERATION VOLUME/SQUELCH CONTROL When the GMA 1347 MAN SQ key is selected, pressing the VOL/SQ knob toggles between volume and squelch adjustment. When the unit is in volume adjustment mode, the VOL annunciation on the lower left of the VOL/SQ knob is lit and volume can be adjusted. When the unit is in squelch mode, the SQ annunciation on the lower right of the VOL/SQ knob is lit and squelch threshold level can be adjusted. NOTE: When the MAN SQ key is not selected (auto-squelch is active), pressing the VOL/SQ knob has no effect on the VOL/SQ selection state and VOL is automatically annunciated. When transitioning from auto to manual squelch, the unit returns to the previous VOL/SQ selection (see table below). NOTE: The volume and squelch controls for the COM and NAV radios are located on the PFD and MFD bezels (refer to the VHF NAV/COM Pilot's Guide for details). Intercom VOL/SQ Intercom Volume Control Intercom volume can be controlled with the VOL/SQ knob. The small knob controls the pilot ICS volume. The large knob controls the copilot/passenger ICS volume. Turning either knob clockwise increases audio level. [. . . ] When ICS is connected to the copilot side in COPILOT mode, the passengers hear the passenger audio, the pilot and MUSIC 2 COCKPIT VOICE RECORDER INTERFACE The GMA 1347 provides the ability to interface to a cockpit voice recorder (CVR). The unsquelched pilot microphone input (all vocal inputs from the pilot) is combined with all audio heard on the pilot's headset and cabin speaker and is output to the pilot CVR channel. The unsquelched copilot microphone input is combined with all audio heard on the copilot's headset and the cabin speaker and is output to the copilot CVR channel. Simultaneous COM Transmission Dual GMA 1347 installations allow both the pilot and copilot to transmit simultaneously over separate radios. When either COM transmitter is keyed, transmit-interlock shuts off the other COM receiver. [. . . ]
