nad c720bee zone 2

I'm pretty sure the Zone 2 output is just a glorified record-out.

Make sure one of the little green LED's is lit around the Zone 2 knob on the front of your c720bee, as the zone function turns itself off when the amp's off, and you need to 'wake it up' by moving that knob, or using the extra little remote they give you.

I've never used the zone 2 on my 720, except once when I briefly used it to send audio to a subwoofer.

I mentioned the green led's because mine stay off unless I turn that zone 2 dial to 'wake it up'. I think that was after I turned the zone 2 off using that little remote they give you.

You should be able to send any source connected to your 720 to your second room using that zone 2 function, regardless of what you're listening to in your main room; let me know how you go, as I'm interested myself!

You must have bought yours more recently, as my main remote is the SR5. Mine also came with a tiny remote (ZR3) which allows you to control the second zone from another room using a remote IR sender. This mini remote turns my zone 2 on and off.
