Overview
About the GTM
The GTM combines the multiple functions required for interfacing and communications in eSports tournaments into one simple-to-use device. It provides the interface for individual gamers, generates the internal team intercom mix, and allows full remote control by tournament engineers — all over a single PoE network cable.
The top panel contains three large level controls — GAME, TEAM, and ME — allowing each player to adjust their personal headphone mix in real time. A multicolour LED ring around each control indicates the current level position at a glance.
Separate device modes mean the GTM can also be used by Coaches, Referees, and Arena Announcers. A stripped-down variant with no top panel controls (GTM SI) is available for system integrators where player access must be restricted.
The Background Audio Guard facility reduces background noise by up to 40dB across 34 separate frequency bands, preventing unwanted arena noise from leaking into the team talk mix and eliminating any competitive advantage gained from overheard audio.
