The GTX-PC is a black-only or red-only user console that consists of a standard PC running Compunetix’ GTX user interface software. It displays 4 pages of 48 line keys (192 total). The PC connects with the MVP switch via an IP network. The console uses a USB push-to-talk headset. All audio processing is done by the PC. The PC does not need to be dedicated strictly for use as a mission instrument; it can run other applications such as the MVP administration client at the same time.
