The AMX240 is a full-featured audio source selector panel, intercom, and Marker Beacon receiver that provides outstanding features and sound quality, while incorporating Avidyne’s legendary “Flying Made Simple” user interface. Large, easy-to-read, LED backlit buttons provide simple mode selection and at-a-glance annunciation of your current audio and intercom configuration.

Supporting three transmitter inputs, nine receiver inputs, plus two inputs for stereo music and five unswitched inputs, the AMX240 also features a six-place high-fidelity stereo intercom, public address (PA) function, plus Bluetooth® music and full-duplex cell phone interfaces.

Making Flying Simpler

The AMX240 represents the state of the art in audio management and it is designed to make your flying simpler. Dual radio monitor capability allows the pilot to listen to Standby frequencies on the IFD-Series VHF radios with automatic muting when active frequency is in use. A dedicated Replay button provides a “say again” function that repeats previous ATC communications, and a dedicated Split button allows the pilot to transmit on Com 1 while the Copilot transmits on Com 2. 

The AMX240 is a slide-in replacement for the GMA340 audio panel, making it a great choice for upgrades, as well as for new installations.



The AMX240 is a perfect complement to Avidyne’s Entegra Release 9 and the new panel-mounted radio stack, which also includes the IFD540 GPS/NAV/ COM and AXP340 ADS-B Extended Squitter ModeS Transponder.
