Awesome Little Mixer!
I have had this mixer for about four months and have used the USB interface to record and to playback audio and it works really well. I have not used it in a live situation yet though but I believe will work amazingly for that. All of the channels sound amazing and the FX are awesome the built in compressors are good and the I/O is good. After getting it however I have realized it is set up more to be used as a recording studio mixer than a live mixer; since it has an alternate output that is triggered by muting the channels that you don't want to send to the main mix (which is what would be recorded by your DAW) when recording. I have used the free software download the Behringer offers on their website but have found that I don't really care for it, as it does not have any built in effects and it's hard to to playback and record at the same time when using backing tracks or prerecorded tracks. So I found another free DAW to use that I like much better (Presonus Studio 2 FREE). If you install the driver for the mixer from the website (on PC) using studio one it will automatically register the mixer and that's all that has to be done, it took me literally five minutes after installing studio one.
Overall I love this Little Mixer it has plenty of inputs for me to use. I would totally recommend for anyone who needs only a few inputs, built in effects and a monitor send.
