MATRIX AMPLIFICATION

6. International Voltage Selection

. Although the GT series amplifiers are labelled as per the voltage of the region they are sold

for use within, it is possible with most models to select alternative region voltages internally via

an on-board switch.

This allows for selection of 230v or 110v modes respectively at +/- 15%.

This is approximately 200 to 265v or 95 to 125v.

If you are unsure about undertaking this procedure, please refer to qualified service

personnel.

To access the internal switch, firstly disconnect amplifier from all equipment & mains supply

as lethal voltages are present inside. Next remove the screws on the lid shown below with a

suitable cross head screwdriver, the lid should now simply lift away without obstruction, should

any resistance be encountered, inspect for further fasteners holding the lid down.

Within the region indicated below by the dotted area a internal view similar to that shown

below should be visible. With a finger or ballpoint pen move the switch shown into its alternative

position for secondary voltage mode. Re-assemble amplifier ensuring all fixings are tight before

further use.

Note: - Ensure correct voltage for region is always selected, otherwise damage is

likely to occur !
