AA80

The AA80 InterVOXT is an advanced intercom system for general aviation aircraft. Built to NAT's high quality standards, the AA80 offers exceptional quality and performance in a rugged compact design. NAT's exclusive InterVOXT and ANFT technology deliver high output power and reliability to ensure trouble free operation.

InterVOXT utilizes NAT's unique ANFT system of Active Noise Filtering through audio processing and selective bandwidth to produce clean crisp intercom audio under difficult and noisy conditions. The results are better on-board communications and greatly reduced pilot noise fatigue. The high output power and low distortion of the AA80 insure a sufficient level for all types of headsets and flying conditions. Short-circuit protection is provided to ensure continued operation in the event of a headset failure. Music and ICS muting are also provided to eliminate interference with reception of ATC.

GMA340

The GMA 340 features innovative LED-illuminated push button controls that allow audio selection of both NAV and Comm audio. Large buttons activate the Comm microphone and audios for up to three Comm transceivers to simplify cockpit workload. Another feature of the GMA 340 is the Split Comm, which allows the pilot to transmit/receive on Comm 1 and the co-pilot to transmit/receive on Comm 2.

MASQT processing reduces ambient noise from the avionics inputs. Comm transmit indication is also provided. Speaker selection is available to monitor the aircraft radios or to make PA announcements. There are two unswitched inputs for telephone ringers, altitude alert warnings, or other warning tones. In addition, the GMA 340 includes a six-place VOX intercom with three selectable modes of isolation, dual stereo music inputs, and independent pilot, co-pilot, and passenger volume control. Each microphone input has a dedicated VOX circuit to ensure that only the active microphone is heard when squelch is broken. Special cabin noise de-emphasis circuitry enhances cockpit communications. Also standard is the three-light Marker Beacon Receiver/Indicator with high/low sensitivity selection and SmartMuteT marker audio muting.
