The AMX240 is a full-featured audio source selector panel, intercom, and marker beacon receiver that provides outstanding features and sound quality, while incorporating large, easy-to-read, LED backlit buttons providing simple mode selection and at-a-glance annunciation of your current audio and intercom configuration.

Supporting three transmitter inputs, nine (9) receiver inputs, plus two (2) inputs for stereo music and five (5) 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.

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 perfect complement Avidyne’s panel-mounted radio stack, which also includes the IFD540 and IFD440 FMS/GPS/NAV/COMs and AXP340 ADS-B Extended Squitter ModeS Transponder.

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.

Six-Place Audio Intercom with Isolation

The AMX240 features a pilot-selectable stereo or mono, six-place intercom system with automatic voice-activated (VOX) squelch for each mic input.

Pilot, crew, and passenger isolation settings are easily selectable with a single dedicated button, and are graphically displayed for clear mode annunciation. Crew Isolated selected.

Dedicated knobs for Pilot, Copilot and Passenger intercom volumes allow for full customization for personal preferences without relying on headset volume controls.
