This is my first posting. I have a D400 and wondered if it is possible to make live all the speaker outputs in order to attach 2 pairs of speakers?
When you do the configuration for dual mono, there's actually the option to go dual stereo as well. You won't get 400 Watt per channel though and there's always only going to be one volume control. Unless you just use both amps separately. Roon gives you the option to play the same music on both amp if you so choose.
Tell us a bit more of what you're trying to achieve and we might be able to help better.
BTW, welcome to the forum Spicy!
Thanks. I hadn't realised you can just select stereo for each. Obvious really. Thanks for your help and the warm welcome.
