Description

Going above and beyond the call of duty of a traditional Comm, the GTR 20 includes a 2-place stereo intercom that is ideal for 2-seat aircraft; no additional hardware is required to communicate with your passenger. Advanced auto squelch automatically senses the noise level in the cockpit and adjusts the mic squelch for effortless intercom use regardless of the cockpit noise level. G3X Touch interface alloes access to emergency frequency tuning, pilot audio isolation, saved frequencies list, music mute or push-to-talk. Plus, optional installed remote switches on the flight controls allow pilots to keep their hands on the controls while performing functions like swapping the active and standby frequencies.

Enjoy Crystal-Clear Standby Frequency Monitoring

With its standby frequency monitoring feature, the GTR 20 gives you the ability to listen to ATIS while monitoring ATC. Swapping your active and standby frequencies is done through the G3X Touch display or optionally installed switches on the controls. Even in single-radio aircraft, you’ll no longer have to worry about missing an ATC call or other critical transmission. 3D Audio capability separates the active and standby frequencies in your headset so it’s easier to differentiate between sources.
