GARMIN® GMA™ 342 TSO'd Panel-Mounted Audio Control Panel SKU: GRMN-ACP-GMA342

The GARMIN® GMA 342 is an affordably priced yet loaded with features TSO'd panel-mounted audio panel providing direct slide-in replacement for legacy GMA 340 or select third-party units. It can support dual comm, dual nav, 3 aux receivers and 2 wired stereo music inputs — enhanced with bass boost levels, equalizer settings and exclusive 3D Audio technology that spatially separates the multiple communication sources entering the pilot's headset.  Up to 2 dedicated stereo music sources can be connected via the unit’s rear connectors. With stereo headsets, incoming audio is spatially separated to reflect how different audio sources come from different directions. An automatic digital voice recorder on GMA 342 continuously captures the last 60 seconds of incoming active comm audio for instant playback with a single button press. Advanced auto squelch technology automatically adapts to a quiet or noisy environment without clipping words or cutting out during conversation.

Accessories: If not included in the ordered unit, installation Kit and other accessories are available at additional cost.
