Designed for experimental and light sport (LSA) aircraft, the versatile GMA 240 audio panel brings flexibility and functionality to the cockpit at an affordable price. This non-TSO’d audio panel comes with many of the popular control and indication features found on the GMA 340, while excluding those functions not used in experimental and LSA operations — resulting in a remarkable cost savings to you.

Upgrade Your Intercom

The innovative, reliable GMA 240 comes with full audio panel capabilities. It includes a 4 place stereo intercom system and support for 2 stereo music inputs. It supports dual COM, NAV and AUX audio inputs. In addition, 3 unswitched audio alert inputs are provided for connection to external warning tones. The GMA 240 has a full-duplex telephone interface with intercom isolation for private telephone calls by the pilot or multi-party calls with crew and passengers.

Listen to Your Favorite Tunes

The GMA 240 really shines when it comes to music support:

  • 2 differential, hi-fidelity stereo music source inputs
  • Front panel music volume control, source selection and music on/off button
  • Dedicated controls for music muting by intercom and selected radios
  • Easy access mini-jack for media player, cellular phone, etc.

Connect up to 2 dedicated music sources to the rear connector (e.g. XM music and CD player) and over-ride one of those sources at any time by connecting a device (e.g. MP3 player) into the 2.5 mm front jack. Any selected music source’s volume can be controlled by pulling out the intercom volume/squelch knob. If connecting a GPSMAP 396/496 to the GMA 240, you can adjust the XM music volume directly from the GMA 240. And the multifunction phone/audio mini jack on the front lets you route cell phone calls or iPod/MP3/XM Radio players right through your aircraft headset — with selectable instant muting when radio transmissions are received from ATC.

Operate with Ease

The easy-to-use GMA 240 features convenient, LED-illuminated button controls for audio selection. Plus, to make the entire audio experience quieter and clearer, MASQ (Master Avionics Squelch) processing helps filter out unwanted radio static and interferences. The GMA 240 is designed to be an easy-fit installation for today’s most popular experimental/kitplane and LSA cockpits.
