REL Strata III Setup - Help

You stated that it is a 2 channel system, the best method is to use the neutrik connection and use the "High" level, if you use only the neutrik connection then the LFE or line setting is not used ,it is only used for the "Low" level, but the phase setting is still in use , see Srwooten's answer. Hope this helps

Fatman is right.
As far as phase is concerned, I would settle for the position where the bass is loudest and best defined. If your sub is behind the right or left of a main speaker it is generally zero, but not always. You will have to use your ears. Vice versa if you placed the sub near your listening position, but again, " it ain't necessarily so ". Depends heavily on speaker placement and your room.

Thanks for the response. I am using the nuetrik connection in 2 channel only and the sub is in between the 2 speakers. Based on the answers above I should not use LFE for 2 channel and the rest of the settings can be used based on how it sounds in my room.

Srwooten - what is PRAT?

One of the pages in the manual - which you can obtain online - gives step by step instructions. Get it and do it, carefully. It gives amazing results.

After work I could write this out this evening from memory! I don't have the time at the start of the work day alas.

If you follow the steps you can arrange for the sub to match seamlessly to the main speakers. My guests ALWAYS say this sounds GREAT but I can't hear the sub. Then I turn off the sub, and they are like OH.

I have REL subs in 3 rooms of my house.

As I recall, FIRST you test the phase by arranging for the sub sound to overlap the mains. ......

I also purchased a test cd from Stereophile that has a track with bass notes, 15 seconds each, at specified intervals. A test cd like this is IMMENSELY helpful although not absolutely necessary.

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.
