I bought this to use in a rehearsal room with a band. We are a four piece but use drums, 2 guitars, bass, 3 synths (stereo),laptop and 3 vocals so needed lots of inputs.
Previously had a Yamaha mixer and Zoom R16 recorder but this allows us to play live and/or record without continuously plugging in and out inputs into the mixer and recorder. Recording onto SD card is easy.
Sound quality is great, loads of headroom on preamps, channel tweaking is easy. Greatest of all though is the ability to have 6 individual headphone/monitor mixes.
Haven't tried mixing using it hooked up to my DAW yet - will report back.
Con: Sure, it's a bit plasticy and the knobs aren't pro quality but sitting in a bandroom with the occasional trip into the outside world it is easily robust enough to last a long time.
1 Year update: I can confirm this product is great. We've used it to produce high quality band demos. Instead of recording all the tracks onto SD card and then importing into a DAW (which is very easily done) we now have it connected directly to a laptop and record live into the DAW. We have a template for our band and all the inputs set up in the DAW so it's really quick and easy to record rehearsals or demos.
Highly recommended, great value.
