Re: Well, THAT's Not Gonna Fucking Work!The apparent polarity inversion is troubling. Not questioning Bennett's measurement capability, he knows what he's doing, but I'd double check the cables & the settings in the DSP. I've had things like this bite me in the backside before.The reason I suspect the DSP settings is there seems to be a different propagation time (latency) through the DSP for the LOW output (purple) & HIGH output (green). Even though there is no impulse response shown the different slopes of the phase response curves are indicative of this. If the arrival time of the test signal was the same from the LOW and the HIGH outputs the phase traces would have the same slope in the high frequency region.There may also be other causes for this behavior. Just a thought.
