I have NO idea if anyone makes such a thing, and my Google skillz apparently suck cuz I can't find a damn thing about it.
Does anyone out there make an audio compressor unit that uses Optical Cable ins/outs? I'd DIE to put on in my home theater system so even out the audio between channels even more than what my satellite system does. It works ok, but it could be so much better.
I've never heard of an outboard compressor with optical/digital ins/outs.
