Surround back or surround's? I just hooked up my htr5890 and I am attemting the auto setup and I got the error that my surround backs are connected but not my surrounds. Also at the beggining it had me turn my sub output to half and the crossover cutoff to max. the sub is a paradigm PW2200, should I keep these settings? It is being used with Paradigm Monitor 3 v.3's as fronts and a CC370 v.3 as a center.
