REL Strata III Setup - Help

LFE is low frequency usually from a AVR sub output. Use this if you use the crossover in your AVR. Line is a full range signal from your line out. Use this if you are not using a crossover, and adjust the crossover setting on your sub to blend the best with your main speakers.

"180 DEG" or "0" as far as phase goes" Set this where the bass and PRAT are best at the listening position.

Hope this helps-

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.

Just be forwarned that if you are running a balanced system or mono amplifiers that you can connect the two channels together if you are not careful with the speakon connectors. This basically turns your system into a mono system, something you may not notice immediately if you are running with a 2-channel amp versus a pre-pro where you can run a speaker level test (doing this reveals this issue, ie. when just the left front speaker is supposed to play, you also hear equal noise from the right front speaker).

I went to the Sumiko site and the manual they have online has much more information than the thin manual that came with the Strata 3.

Thanks for all the input! I will be trying it out.

PRAT stands for Pace, Rhythm, And Timing
