Overview
About the GTM
The GTM Mobile extends the proven GTM platform with hardware specifically engineered for the demands of mobile phone-based tournaments. Beyond the standard functions of game audio monitoring, team intercom, and referee interfacing, it introduces a wired USB-C connection to the player's Android device — providing reliable bi-directional data independent of Wi-Fi, which is critical in large, congested tournament venues.
Because mobile games place a sustained drain on battery, the GTM Mobile also delivers high-power USB-C charging via the same cable — up to 15W (5V 3A) — when connected to a PoE++ switch. This eliminates mid-match battery anxiety without adding cables to the player station.
Like all GTM variants, it supports Coaches, Referees, and Arena Announcers through separate operating modes, and is fully controllable from the GlenController Windows 11 app. The top panel carries the same three-control mixer — GAME, TEAM, and ME — each with a multicolour LED ring for immediate level readout.

What the GTM Delivers
Mobile Phone Support
- Wired USB-C to Ethernet adapter provides bi-directional data between an Android device and the GTM Mobile — more reliable than Wi-Fi in large tournament environments
- High-power USB-C charging (15W, 5V 3A) delivered via the same USB-C cable when connected to a PoE++ switch
- On mobile devices, USB audio delivers 1× stereo input; on PC, 2× stereo inputs are available
- GTM Mobile can also accept power from a USB-C PD-capable PC — note that mobile phone charging is unavailable in this mode unless PoE++ is also present
