All connections should be made before the mains adaptor is plugged in.

of the X-DAC

The DAC has two inputs, one an optical “Toslink” and the other an S/PDIF* co-axial RCA socket. Either one is automatically selected by the presence of a digital signal, but if both are accidentally connected at the same time, priority is given to the first of the two inputs presented. * Sony / Philips Digital Interface Format

Using good quality co-axial audio leads, connect left and right audio outputs from the analogue output sockets on the back panel of your X-DAC

your amplifier system, for example the CD or auxiliary sockets.

The co-axial RCA digital output can also be connected to suitable external digital equipment if required.

Now plug the DC connector lead from the power supply unit into the X-DAC socket, and plug the power supply itself into a convenient wall mains outlet. The

The LOCKEDdata indicator LED on the front panel will light to show that the DAC has sucessfully locked on to the incoming data stream, and either the CO-AXIALor OPTICALLED shows which input has been selected.

Adjust the volume control on your audio system to obtain the preferred sound level.

If there is no incoming digital data to either input, the CO-AXIALand OPTICAL LEDs will flash alternately, and the LOCKEDLED will flash more rapidly.
