This box did not work for my digital piano, a Casio CGP700, a cousin of the Casio Privia pianos. There was no low end at when connected to my church PA system. It is quite heavy, looks good quality, but it just didn't work, unfortunately. I suspect that my Casio is a very picky keyboard, since the Behringer didn't work either. The only one that I know works is the Whirlwind IMP2.
