[momunist]

i had already checked both of those (and many other) software setting. but we did find the problem. so here's a new one. when i went and checked out the units, i found a problem with the extension port on one of the units. as long as the bad unit is the second in the chain, the problem goes away, but if it's the first and the other unit is connected to it's extention port, the distortion is there. we just switched the order of the units to make the session run, but that's the first time i've seen or heard of that one. either way, problme solved, and i'll send the unit in when there is some downtime. thanks for the reply!
