My brother owns the outlaw 990 and an EP600 and after spending a couple of hours with it we concluded the automatic delay is not accurate. The sub was 10 feet away and the 990 kept giving us readings of 24 ft. I've yet to find an auto delay function in any receiver which accurately sets sub delay. The acoustical physics involved make it a daunting task to set delay properly. Auto- equalization rarely comes out right with bass frequencies. My suggestion is to add 2.5 to 5 ft to the actual distance then fine tune depending on your ear. With my brothers an additional 4ft gave the best result.
