Ok so I've been bit by the sharing inputs problem on a pair of M32s using a shared stage box between the two. I know that since I have switched over to digital my noise (60hz buzz) problems have pretty much gone away regardless of whether I am using a single desk or a pair (FOH&MON). I am thinking about getting a split so that I can not have to deal with the sharing inputs problem again. Anyone have experience using a non transformer split as opposed to a transformer split on digitals?
