Hooking up our powered speakers, such as the A2+ and A5+, to a television can depend what connections might be available on the tv for audio output.  If your television has analog outputs (such as RCA or a headphone out) you can use that to connect directly into the back of the speakers using either a mini-stereo or RCA cable.  If your television only has an optical output, you would need to hook up the television to something like our D1 DAC to convert the digital signal to analog; you would need is a optical/toslink cable in a set up like this. 

If you're using the HD6 with a television, you would just need to connect your television's digital output to the optical input on the back of the powered HD6 speaker using an optical cable.
