your probably already aware of this but your levels need to be paded and balanced before entering your modulators on the off air side. your dss stuff should remain the same prior to hitting the receivers and before hitting your modulators. your mod's should have a gain control for both audio and video that you balance the out puts on all before hitting your combiner. get 'em all even before hitting your le and pad at le accordingly. hope this helps or at least makes sense. adios, Mike
