If both your PC and your home theater receiver have this connection, that’s the one you should use, because it provides the best quality. In other to connect your PC to your receiver using this connection, you will need a fiber optic cable, which comes with your receiver.

Figure 12: Fiber optic cable needed to connect your PC to your home theater receiver using optical digital connection.

On the receiver, plug one end of the cable to the input labeled ”Digital Optical In“,  ”Digital DVD In“ or similar (on our receiver this input was labeled ”Optical Video 2 In“). Before inserting the plug, pay attention if the receiver input is closed or not. If it uses a squared black peg, you should remove it before trying to insert the plug.

Then connect the other end of the cable on your PC, on the black squared plug. But before inserting the plug, remove the black squared peg that protects the connector, like we show in Figure 14.

Now everything is connected and should work just fine. You need to change the input selector on your receiver to ”DVD In“, ”Digital DVD In“ or similar (on our receiver we had to change its selector to ”Video 2“ since our cable was connected on an input labeled ”Optical Video 2 In“).
