INTRODUCTION

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 Dante Networking (AES67) and AES3 Digital inputs are also available.

TROUBLESHOOTING

We aim to resolve possible issues by providing solutions in this section:

1.  The amplifier does not start up
   Check the power supply cord. If it is correctly connected and the red led on the front panel does not light on, check the fuse situated in the input of the power cord.

2. The amplifier starts up but there is no sound
   Check that the amplifier is being provided with a signal in the correct input, A, B, C or D. If the signal does reach the amplifier, the green signal LED will light.

3. The resulting sound is “strange”
   Check that the outputs and their corresponding cabinets are correctly linked. Always be careful in increasing little by little the cabinets volume channel by channel in order to check the correct connection and not to damage the transducers.

4. One of the cabinets (with the same signal) sounds less than the others
   Check that the joining cable from the amplifier to the cabinet is well balanced otherwise the output signal will fall 6 dB.
