GETTING STARTED, POWERING UP & CONNECTIONS: 

Your GT Series amplifier comes equipped with a power lead specific for the 
requirements of your country. Use only the correct lead with the correct rated 
fuse for your country’s power requirements. Use of an incorrect lead or fuse 
rating could lead to damage of your amplifier.

1.Connect the supplied mains power lead to the IEC inlet on the rear of the 
amp.

2. Connect the signal source (this can be your pre-amp, modelling device or 
main outs from your effects unit) to the inputs on the rear of the amp. If you 
are running in mono from your source, then only use one channel of the amp 
and keep the amp in stereo mode. Note: If you are running the Matrix amp 
as part of a wet/dry or wet/dry/wet system then make sure the connections 
between your ampfier or source are in place to the effects system you intend 
to use before feeding the signal to the Matrix amp.

3. Connect the GT amplifier to a speaker or cabinet with a good quality 
speaker cable. Never use a screened (shielded) guitar cable for this as you 
may damage the cable and the amplifier. The GT-series amps will accept 
various standard impedance cabinets and even non standard but bear in 
mind that the total load must NOT exceed 4 ohms per channel (or 8 ohms 
in bridged mode). 

4. Making sure that the amp is turned off at this point, power up your signal 
source (this prevents any unwated signal noise transmitted to your 
speaker(s). Now with the volumes on the amp all the way down, power on 
the amplifier via the power switch located on the front. You may hear a 
slight “thump” as the unit is powered on. This is perfectly normal.

5. Adjust the controls of the input source to a required level (ideally 0db or 
.775v) and steadily increase the GTs volume until a sufficient level is 
achieved. 

6. Adjust the levels of the relevant volume controls on the Matrix amp until 
desired volume is achieved.

 

 

     

 

NOTE: 

Unlike a Valve powered amplifier, it is not 

necessary to connect a speaker (or load) to the amp 
whilst it is powered on. Powering on or operation of the 
amp without a speaker or load attached will NOT damage 
the amplifier.
