Connecting to Audio Systems

To a Stereo Amplifier/Receiver:

For digital processing, connect the COAXIAL or OPTICAL output to the corresponding input on your DAC or AV receiver. Select the appropriate input on the receiver.

Note: Use only one set of outputs at a time (Analog or Digital) unless your system is specifically configured for both.
