The GMA 350H audio panel provides audio selector functions of microphone and receiver audio selection. The audio panel includes ICS, night vision compatible green annunciation and backlighting, a front panel entertainment/telephone jack, and an optional marker beacon receiver. The GMA 350H also features 3D audio capability. a. The Voice Recognition feature is not enabled for this installation. 2. The components of the GMA 350H installation include the GMA 350H audio panel unit located in the avionics panel, and an entertainment jack located on the lower copilot side of the pedestal, and the marker beacon sensitivity toggle switch located on the lower right side of the circuit breaker panel and marker beacon antenna (if configured). The GMA 350H installation does not include an external speaker/PA system. 3. The GMA 350H may be configured with traditional avionic component systems (such as VOR/LOC/GS, GPS, NAV/COM, transponder, etc.) or with the Garmin G1000H Integrated Flight Deck. The system block diagram is shown in Figure 7-2. 4. Power to the GMA 350H system is provided via the battery switch (BATT). Power to the GMA 350H audio panel is provided via the AUDIO PANEL circuit breaker (2 amp, G1000H configuration; 5 amp, standard configuration) located on the left side of the lower panel (Figure 7-1). 5. The marker beacon receiver (if configured) detects three marker beacon signals (outer, middle, and inner). The corresponding marker beacon tone is heard. The signal sensitivity can be set with the MKR SENS toggle switch (Figure 1). The GMA 350H does not have a discrete marker beacon display. Depending on the aircraft configuration, it may be displayed on other avionic equipment.
