GTX Series
Amplifiers
The GTX Series are 4-channel, extremely high power level amplifiers designed to withstand the rough requirements of the touring market.
With outstanding, high efficiency, these amplifiers have been equipped with a quality FIR-DSP with high performance 96kHz DSP processing and a large IPS display with a touch panel user interface.
Advanced Audio Power Control Management has been implemented in the design of the GTX series. This enables the user to configure the division of power between the channels via the DSP enabling them to obtain maximum power through just one single channel if desired.
Optional Networking AES67 and AES3 Digital inputs are also available.
