Just got a S/H Rel Strata II to compare to my M&K V75 Mark II The winner stays, but I need some info tto help me set it up. The three dials are:- FINE, GAIN & COARSE. How do I use these to setup/configure the crossover freqs for the sub? Also... Advice on the Rel site recommends connecting the Neutric connector as well as the phono for AC3 setup. The Strata II has no mode switch, so will it be OK receiving the speaker level signal simultaneously to the Phono connection? Other advice on the setup page on the site recommends NOT using the spikes??? Thanks for any help, Mark.
