Sumiko has set up made simple and set up made simpler on their web site. They recommend the soundtrack from "Sneakers" to use to set up. I got it on Amazon and it is useful but any recording with repetitive bass will work.
REL Strata III Setup - Help
I have a STRATA III and don't quite understand the directions, in particular the mode selector. I am running a 2 channel system with Dali MS5 speakers. It is not clear to me whether the mode should be LFE or Line. Or if it should be "180 DEG" or "0" as far as phase goes. Reference page 5 of the instructions where they "explain" this. Just wondering if any of you have advice in this area? Thanks for your help.
