There's an interesting discussion over on TBL about the inherent phase reversal you get when you bridge a particular Crown amp into a pair of cabs. Is this common to most or all power amps? From reading the discussion, this phase reversal can seriously affect the tone of your rig - the comment was "all the booty was gone" - making it sound much thinner than it would unbridged (duh). I haven't noticed this phenomenon with my Carvin DCM-1000. My Carvin forces you to use a single Speakon output when you bridge - is that how they get away with it? Do Crowns (or others) use a pair of speaker outputs when bridged, which would then be out of phase to each other? Or is this phase reversal an input or amplification stage issue having nothing to do with output configuration?
