Universal Phantom volume control options

[Spud]

An AD converter and an optical splitter would do the trick. The speakers need to be in direct optical mode.

Thanks or answering, ragwo! Could you elaborate a bit?

I need to use the Pre Out right? That means I have to use the AD converter as you suggest. One AD converter to a splitter is better than two AD converters to get the same two optical out? And what would happen to the volum control. Will it pass through the converter and the splitter no matter what, or do I need some special equipment? I would like to avoid low quality devices which introduce white nose as well. I heard some had a problem with that.

Any suggestions for specific equipment? Preferably cheaper things, as long as it don't ruin the sound.
