Other highlights include industry-leading Auto Squelch, a digital clearance recorder and marker beacon receiver. 2 dedicated rear audio connections, allowing hardwired sources — such as SiriusXM® satellite radio or other high-fidelity music inputs — to be played and distributed through the audio system.

Listen in Virtual 3-D

For your radio communications, advanced 3-D digital sound processing, first introduced to general aviation by Garmin, enables GMA 342 to approximate how the human ear normally hears and registers multiple audio sources in space. With stereo headsets, incoming audio is spatially separated to reflect how different audio sources come from different directions around you. This makes it easier to distinguish one source from another — and helps you focus on the higher-priority calls coming into your headset. For example, COMM 1 will seem like it’s coming from the left while COMM 2 will seem to be coming from the right.

High-performance Auto Squelch

To further enhance the cockpit audio experience, advanced Auto Squelch technology the squelch automatically adapts to a quiet or noisy environment without clipping words or cutting out during conversation. A high-performance digital signal processor constantly monitors ambient noise level and automatically adjusts the mic squelch level required to keep intercom conversation as comfortable and natural as possible — whether you’re talking over engine noise in flight or quietly going through your preflight checklist on the ground. The unit’s Auto Squelch technology automatically adjusts for these variances, allowing you to speak at normal levels, no matter what the ambient sound conditions may be.
