Operation of the device
Power the device

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.

down to select the RCA input.
