I was very pleased with how easy it was to set up and use the new mixer. I find it is very well suited for what I need at this time, and I have incorporated it into my setup, replacing the Edirol mixer.
If you want realtime e.q. and effects control, it isn't for you. If you want to change those setups you must use a PC program (free). The default reverb is very good and even the level is preset. Again, if you want to change it, you must do it via USB.
I had a guest singer (DickieT) so a few songs and I plugged a mic (Samson Q7) into channel two and it sounded very good with the preset effects.
The mixer is about 6" x 8" and, together with not needing a power supply other than USB, the footprint is extremely small.
Input and output options are plentiful and varied. I like it.
Just for your information, I got mine from Musician's Buy because they sent me an email touting it. I checked around and most online stores don't have it yet or are sold out.
It comes with an offer to get a free Ipad camera adapter and free software.
