I agree with David, when you get used to the MT, it is a breeze to use. It is a bit foreign though at first. I like the meters, but if you don't keep them backlit all the time, which I do like to do, the red clipping lights are a great indicator. The unit can clip a bit without distortion, so I like to get the levels just below that point so the red lights are not coming on. Of course some of that depends on the music and the difference between the softest and the loudest parts.
I use a Zap battery and power is never an issue. I cannot remember the last time that I ended a show and did not have a fully charged internal battery. And that said, I never start with a fully charged battery.
