GMA™ 347

Número de referencia: 010-00275-01

Descripción general

The GMA 347 audio panel adds a digital voice recorder, automatic squelch and full-duplex telephone interface to the GMA 340. These features streamline cockpit management, enhance flight safety and improve communications between flight crews, ground controllers and passengers.

Never Miss a Message

GMA 347’s digital voice recorder helps you manage the demands of a busy cockpit. The automatic voice recorder continuously captures the last two and one-half minutes of audio switched through the panel. So if you ever miss an assigned frequency or part of a clearance, simply press the “Play” button to recall the message for review.

Filter Static and Interference

GMA 347's automatic squelch option makes your entire audio experience quieter and clearer. This option filters out radio static and interference. Yet, for those situations when faint, far-off audio signals can be blanketed by ambient noise, the 347 offers manual squelch adjustment.

Make Private Phone Calls

In addition, GMA 347 has a full-duplex telephone interface with intercom isolation and disable capability. This feature allows private telephone calls by the pilot or copilot, or multi-party calls with crew and/or passengers. GMA 347 also comes with three more unmuted, unswitched inputs with individual volume control for additional audio capabilities

Operate with Ease

With convenient, LED-illuminated button controls for audio selection — as well as split comm capability for pilot and co-pilot, GMA 347 is easy to use. If the GMA 347 ever needs to be removed for service, a “configuration module” makes sure that previous audio settings are retained in the unit.
