Operation of the device

Power the device

First, connect the power supply connector (2) of the amplifier to a main power outlet using the supplied power cable. Press the ON/OFF button (1) on the unit. The

LED on the button will light up. The amplifier is now turned on.

Note: Before plugging in and supplying power to the unit from a main power outlet, be sure to check that the power supply voltage selector on the bottom of the ampli-

fier is set to match the voltage supplied by your household electrical system. Incorrect power supply voltage settings can result in equipment and physical damages.

Input selection

Each channel allows you to select an input independently thanks to two switches (one per channel). Move the switches up to select the XLR input. Move the switches

down to select the RCA input.
