    Ken 504--Vel ct150 sub.When I turn volume up 1/2 or more on sub I here hum.I have tried a other spare sub and same thing.It only will happen when the receiver is on.I have tried the ground plug routine,isolator,moving receiver and cable.If I turn the bypass off I can filter it down on sub but this is not the way to go.I usually go with +3 on receiver and 3-4 on sub vol-gain so it does not get in my way.It does bother me though and I'm out of ideas.[​IMG] Any advice out there?

    I think VEL had some problems with the *CT* series amp modules...I would try contacting them directly, they might have an easy fix.
