The cables supplied with the DVI Audio Extender connect your video source/audio source to the sender. Your display/audio receiver plugs into the back of the DVI Audio Extender receiver. Two CAT-5 cables* connect the sender and the receiver units to each other. The DVI Audio Extender is HDCP compliant.
