I've had the UMC-1 for 9 months now, along with the XPA-5 Amp. There have been NO problems at all, for those worried about the UMC-1s quality. But, I'm learning a lot about the MANUAL EMO-Q. After doing the Auto Mic adjustment, I did some tweaking with the Manual Emo-Q. Since there are 11 BANDS per Channel, it took a while, mostly doing the Center and Sub adjustments. I have 5 'Definitive Tech' Mythos 2s. But, I thought I'd have to dump the POLK Micro 1000 Sub, since it is only has an 8" Driver. But the Micro 1000 is fairly expensive when it comes to Subwoofers, so I tried to make adjustments to it instead. Here is the SUB GRAPH, after adjusting it's 11 Bands. I know, your thinking there is no way that Sub can put out that much Bass with those adjustments.
But, now this Polk Sub is kicking butt and taking names, thanks to the UMC-1!
Don't ask me how. But, there it is. It amazes me, that's all I know.
