In all the time I've had it I've always put a towel over it to prevent dust from getting inside but I know this doesn't stop everything.The MX8000 is the very same mixer that Behringer got into copyright issues with Mackie back in 1999. Apparently the circuit boards for the MX8000 are a direct copy of the Mackie ones but Mackie lost the case.It comes with a printed book, although the book is for the MX9000 I've been told there are only a few differences between the two mixers.
