Behringer U-Phoria UMC22

I can't rate it, I haven't received it yet.

I love this interface. It does not rely on software with my Apple iM4 desktop. If you want to check out a video on it, go to my youtube jellybean4183 channel and look under Bedside Guitar Setup.

After reading other reviews, I was a bit skeptical about this but I bought it anyway. No drivers are needed (windows detects it as a 2 channel audio input), both channels can be independently adjusted, and no lag at all (if you have lag, likely your computer is the problem)

This product worked OK for about 5 months, but it has issues. Then the 2nd channel (Inst 2) went out. I have tried to contact Behringer via their web site several times and stated my issues but I got NO response. I've contacted several Behringer service centers and the techs have told me they have quit servicing Behringer products for years. If you have a problem with their products just put them in the TRASH! That's what the company wants you to do. My unit can with a 3 year warranty. Their website is the worst I've experienced and there is NO WAY to contact them by phone. The unit did not come with a driver and you have to download the AISO4ALL and has a latency problem. The Behringer product line should be pulled from the stores for lack of service and support.

I use this interface for at home recording. I hace had it for a few weeks and so far it works great! I primarily run my guitars through it, but I also use my keyboard as a midi device via USB, even with the Beheringer daisy chained in the USB, I have almost no latency issues.

First impressions were great -- metal chasis, solid knobs, decent USB cable lenght. But not having its own drivers and needing to use ASIO4ALL made me raise an eyebrow. First I tried it on my Win7 laptop over the weekend. Latency was terrible. Couldn't get it below 35ms without lots of drop-outs, which is not acceptable for practicing guitar "shredding" licks. My MOTU AudioExpress on the same machine gets 15ms. But I didn't buy this for home use. I bought it for extra guitar practice at work on my lunch breaks. So when I got back to work I tried it there, which is a Windows 10 machine. Also terrible latency -- worse than the on-board Realtech audio. At that point I was ready to return this thing. But then I found an article on Google which suggested using Windows Device Manager to DISABLE all other audio options. By George! Doing so got the latency down to 21ms, which is close enough for me since this isn't my main audio setup. The one trick on Win10 is that it seems you have to have the ASIO buffer settings configured before you launch the software you're going to use. Adjusting from within the app seems to have no effect -- tried on both AmpLion free and Guitar Rig Player free. Further, to adjust ASIO4ALL settings on its own, you have to be aware ahead of time that you need to select the "offline settings" option during install. But I got all that sorted out and I'm able to squeeze in extra practice time on lunch! One final thought, maybe my Win7 laptop would also get decent latency if I disabled the on-board audio. I didn't know about that trick then, and I'm not about to waste time trying it when the whole point was to have a low-budget setup for my office.
