    When controlling you're master would it be better to max out the power amp knob and use the preamp level as the master??

    Depends on the amp,, but the Peavey I use is that way...
     
  3. Not really. That will guarantee the maximum amount of noise. It will minize the chances of the preamp output clipping though.

    Generally run input pad where the input clip flashes only rarely when you dig in. if you have output meter on the preamp, or clip on the output, turn the preamp master up to where that light rarely flashes, or the output meter reads close to 0 db. High as possible as long as you stay out of clipping. THen turn the power amp up to wherever you want for the volume you need. Doesn't matter if its at 90% or a25% at that point. Control the volume with the power amp volume knob.

    This eliminates the clipping from the input/preamp without sacrificing the noise floor.

  4. I think most people max out the Poweramp and use the preamp as the master vol. I think they do this to have the best signal/noise ratio IIRC.
