Bluetooth® Audio Panel for Your Certified Avionics
Connect Wirelessly with Bluetooth
To further enhance the cockpit audio experience, advanced Auto Squelch technology on GMA 345 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.
This unit is everything it advertises. The Bluetooth connection is flawless. I love the fact that I can now call ATC on my cell phone to copy clearances while my co-pilot friend can also listen in as if we were on the radio frequency. Music and everything else is streamed without any issues. The multiple hardwired input is also very nice, Ive wired the portable Aera 660 into the audio panel and now I can receive aural warnings in my headsets. What is not to love about this unit?
Not too difficult to install - on par with any other panel. 3D audio sounds fantastic! The Bluetooth feature could use an upgrade - I run with a Virb Action Camera and beam cockpit audio to the camera, but the GMA 345 only supports one Bluetooth connection at a time, so I have to disconnect from the camera if I want to call up the Tracon via telephone from a non-towered field for a clearance. That is my only complaint about this unit. Otherwise - easy to use and sounds fantastic.
