The GMA-340 is a very well-equipped Audio Panel. Not only does it have the Marker Beacon section that you would expect, but it also has a Stereo Voice-Activated Intercom system. The GMA-340 was designed to make communicating easier and more flexible. And if you add stereo music, it can make your flying more fun as well.

The Voice-Activated Intercom features six places, and allows easy isolation between the pilot, crew, and passengers. There are separate volume controls for the pilot, co-pilot, and passengers, to tailor the system as needed for hearing or headset equipment differences.

The GMA-340 is loaded with features pilots love, including:

Split COMMs, so the pilot can work COMM1 and the co-pilot COMM2
Remote pushbutton microphone swap between COMM1 and COMM2
Intelligent signal processing, to reduce background noise
Two unswitched audio inputs for traffic, terrain, or altitude warnings, or telephone calls
Failsafe pilot connection to COMM1
Speaker amplifier for announcements
SmartMute audio muting
Large buttons and clear transmit indication
Automatic annunciator dimming
