The GTM combines the multiple functions required for the interfacing and communications required in eSports tournaments into one simple to use device. GTM provides the interface for the gamers, provides the intercom mix, and allows remote control by tournament engineers. There are separate modes that also mean the GTM can be used by the Coaches, Referees, and arena Announcers.
The GTM is available in a stripped down version, with no direct top panel controls, for system integrators

Top Panel Mixer

The top panel contains three level controls for the user to adjust their desired mix into their headphones from the following sources:
GAME: This is the stereo level of the game audio
TEAM: This is the overall level of the team comms channel
ME: This is the level of the users own voice in their headphones

Large controls allow for quick and easy adjustments and a multicolour LED ring around the control indicates the level position
Each control is also a push button that can be used for future developments.

Game Audio Saurce

For compatibility with multiple tournaments and gaming platforms, there are 5 options of sources for the stereo game audio on the rear panel, which are routed to the GAME headphone level control. Source

SPDIF A stereo digital optical TOSLink connection
AUX IN An analogue stereo input on a 3.5mm (1/8") jack socket
USB Stereo USB audio input on a USB C connection
DANTE Two single channel sources are available from the network

HD-SDI
The optional HD-SDI connection is de-embedded to provide 4 pairs of stereo audio sources. These can be mixed to 2 channel stereo using the separate GlenController Remote app. Each stereo pair has a balance control. Typically only a single stereo pair is used for the game audio, but the further. inputs allow for future options and flexibility.
The HD-SDI signal is looped out so the GTM can be used inline of the video signal.
