I just bought this Mackie board this week. While I haven't used it for a live gig yet, I wanted to comment on what I have already noticed about this board just running it through it's paces in my studio. First of all, I am replacing a Behringer board that I have had for over ten years, and that mixer has been a workhorse. I have nothing but good things to say about Behringer, and I have always had great experiences with any of their equipment I have purchased. Now, back to the new Mackie board. I didn't need the owners manual, because this mixer is so intuitively laid out, that anyone who has ever used a mixer will figure this out in just a few minutes at most. I ran a balanced mic cord from one side into my Bose L2 system, and then plugged in a Samson wireless mic, a Roland AX synth, and a Korg M-50 . As soon as I turned up the master volume, and then turned up the channels for each keyboard and my mic, I noticed right away how much more power this mixer puts put. With just a little tweaking of the gain knobs, this board can get LOUD, but what I next noticed is the extreme clarity of the signal this thing puts out. AMAZING!. And at even really loud volumes, ( louder than I would ever have to play live ), it is incredibly quiet. I really had to push the master voulume way higher than I would ever run it , before I started to get that unwanted hiss that we all try to stay away from. This board feels incredibly well built. It is solid as a rock, and you can see and feel the quality of this mixer at every turn. It would seem to me that this board would be best suited for anyone from a single act, up to a four piece band, and there are enough inputs to route all your vocals and instruments with no problem at all. The 16 built in effects are quite understated, but I mean that in the best way possible. They are very useful effects, and you should be able to find something that would suit your taste for vocals, or anything else for that matter. The only effect that I wish they had included would be some kind of reverb and delay combination, but that is not a huge issue, as the other reverbs and delays will do most anything you need. I can't comment on the usb recording interface, because that is something that I personally will never use. but I'm sure it works well. I could go on and on about this little powerhouse of a mixer, but I will end with this. If there is another mixer out ther with this many features, and this type of quality, at this price point, I haven't seen it yet. And don't forget, Mackie is offering a $30.00 rebate up until the end of May, which brings the price of this incredible board to just under $250.00. If you are looking for the all in one mixer for your duo, trio, four piece, or for a single, buy this board now, before they up the price. This mixer is a true winner!
