Before connecting to the mains, make sure that the voltage in your area meets the voltage requirements printed on the power supply.
Digital inputs Sources with an digital output such as a CD player can be connected to the digital inputs (coaxial, optical and symmetrical). A computer can be connected to the USB input. !

Front panel controls Switching on and off The switch on the left hand side of the front panel turns the unit on and off. The blue LED above the ON/OFF switch shows that the unit is switched on. !
