Should have cost more!
Works great. Setting it up, loading the drivers etc, went fairly simple. No problems. The "free" Tracktion DAW did not load on either of my 64 bit computers (laptop or all in one desktop) tho. Loaded fine on my 32 bit Windows XP machine. But not using that for recording. Not a big thing as at the time I purchased this, I was using Reaper. Reaper works great. Since then I have upgraded to Mixcraft Pro 7. Took a while to figure out how link the UMC to the DAW, but got there. The pre-amps sound good, clean and quite, not much coloration. It records with my system very well. For me a good test is to mic up some cymbals, record and listen for high end scratchiness. It passed. The input latency was nil. Undetectable. But the round trip (listening to recorded and live sound together) latency was horrible at 44.1 khz. Went to 96 khz, better. Then went all the way to 192 khz. Much better, 8 mil sec. I can live with that. Not sure if the latency is from my puter, the DAW or the unit or it's drivers. I'm pushing the CPU between 30% and 40% with my set-up. With the Reaper DAW it was much less.The pre-amp sound directly from the mic is ok at 44.1 khz, but sounds much crisper at 96 khz. I don't hear any difference going from 96 khz to 192 khz on mics. I use this mostly with a Mackie 1604 VLZ 4 subgroups plugged into the front. Sometimes just plug the mic directly in. The unit looks nice, professional, solid metal body, compact, well laid out with a lot of nice features, including inserts for effects, nice touch. I run the input gain (record) and output near the top. The unit pretty much just sits there and does it's job, I occasionally adjust one of the gain knobs a bit if I see the clip light blink. I'm not saying that this is the best interface out there, I really don't know what is. I'm just blown away that this unit cost less than most of my stomp boxes and does all that it does. I plan to soon upgrade to a unit with more channels, hope I get as good of results with the new device. Bottom line, I get a really clean professional sounding recordings with this, and it was so affordable. Good luck to everyone.
