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
