Rel Subwoofer Connection via RCA with NAC282

Hi all,
Tried to connect my REL Strata 5 subwoofer via hi level connection from the speaker terminals and immediately got static like popping sound on power up (pa-ba-pa-ba-pa-ba-pa-ba-pa-ba). NAC282 was still in muted startup check. Low level works fine from Onkyo receiver subwoofer out so I am guessing the error is with the input on the REL.

If I were to use the low levev (RCA) connection of the REL with my NDX2/282 what would be the best way to do it? This will be a temporary solution until I repair or more likely replace the old REL with a newer and better model.

@JosquinDesPrez has a Rel with Naim. Or had. Should help.

Hi @flame_rose ,

I agree that this is the best way to connect the sub. I would phone REL and check the way the plug should be wired, it is not consistent. I did this with BK when I wired that speakon.

BE CAREFUL. It is possible to do some damage I was warned.


I have REL subs and have used them with 282, and now 252. The high-level connection is by far the best way to go. The low-level RCA inut is really intended for (and works better) with DSP managed outputs on a HT processor.

Given that, I did once try using the low-level RCA connection with a 282/HiCap. It sounded really pretty aweful and I ended up with boomy, poorly-defined bass, which in turn had a negative affect on everything else in the spectrum, no matter how I tried adjusting it. If you really want to do it you need a special DIN-RCA cable made up to connect one of the spare DIN outputs on the HiCap to the RCA input on the REL. I wouldn’t bother.

Other than that I have always connected my REL subs directly the terminals on my speakrrs (not the amp).

Thank you all for the advice. As the connections seem to be complicated and the subwoofer is in less than ideal functional status, I pulled the trigger on a REL S812 due to arrive Monday.

It will be a better match for the upgraded electronics and future speaker upgrade. Question was whether to buy 1 or 2 of them. Decided to go with one and see how it sounds before deciding.

Definitely two. More is better.

That S/812 is sweet! I have two older R-328 (long discontinued). I would like to have a pair of S/510 but I am done buying components so my 328s will have to do.

What is the sarcasm/seriousness ratio of that statement? The dealer asked for my room dimensions and I sent him a video and as the room is about 10x14 m I expected him to push for two subs but he thought one would be plenty. Not too sure myself.

No, I’m dead serious. My room is 11’ x 17’ and I started with one sub. Adding the second when I found one used was a huge improvement.

RELs website has a sub advisor. You should see what it suggests.

Thanks for the suggestion. I did use the REL subwoofer finder to match to room and speakers (potentials) and that is how I came to the S812. It gave both single and dual options.

The fact that the local dealer had it in stock made it a no brainer at a time when everything has to be ordered from abroad and lead times are in months and not weeks.
