Good but not great. Should have saved a little more and upgraded to a software based processor.
all adjustments are right on the top plate. Nice to look at. There was a little confusion on how exactly to use the input and output maximizer lights. Product manual differs from audiocontrol technicians. Also there was a spike in 5k-8k hertz that could not be attenuated to zero. This range always seemed to be boosted, could have been my vehicles environment and acoustics. The real time aspect was the worst part about this unit and the only reason I purchased. I went through the set up instructions line by line. When an issue showed up I would reach out the either the knowledge base or asking a Technician. The instructions I received differed from one to the other. I also noticed that when the real time is initiated from bass knob it would cut my overall output by almost half of the normal output. Me being the audio nut that I am I stopped using the real time feature on the DQDX and measured and used the time alignment built into my radio. Overall I felt that this does not seem to have the sound quality that my old 3xs had. Also this brought back some ground loop noise that I had eliminated. Well I thought it was !
