I've been running my powered Kemper into a Marshall 2 x 12 and I've found I have to turn it up 3/4 or almost all the way to get it to a decent practice/gig volume whereas in my old rack my Rocktron Velocity would only need to be on around 12 o' clock to easily achieve the volume I need.
Anything I might be missing on the unit as I'm sure there's enough wattage on board?
Thanks!
