Hey all! Just picked up the Behringer HD400 hum isolator and now have the dry guitar output on the HD Pro working perfectly with no high pitched whine or hum Now I'm curious as to which input I should connect it to? Plugged into the Line Input of my ProFire 610 it's pretty quiet (I think they're -10dB inputs). Should I connect it to my guitar input instead and match the volume of the HD Pro in tuner mode? Trying to get everything set up so I'm re-amping at the same level as I originally recorded. Many thanks
