I take your point; it was the preferred option with an active system, but seems to fly in the face of advice.

I have to say thatā€™s a stunning looking set up , Id buy that for a dollar

Would love to have a day with that system

Use the REL diagram.. They kind of know what theyā€™re doing..

24

I search but I cant find exact advice from rel. And my country the rel retailrer not professionalā€¦

25

Try their website. Google is your friend

26

I know, but two-three tipes connection menthioned. Thatā€™s why I asked here

27

The post from @HungryHalibut is essentially the same as the diagram I posted, which is a screenshot of the S510 manual from the REL website. Whether you are better connecting the black wire or not might depend on whether you have the RELs powered from the Niagara as well as the rest of your equipment. I couldnā€™t work out what the Niagara does with the mains earth.

Niagara powered. Thankā€™s all guys, I tried both of them and I write the experience

There are special Rel bassline blue cable for Naim amplifiers. Just visit Rel website for info.
You will find it under ā€œ accessories ā€œ

True. But be sure to read all the words. There are a lot of wordsā€¦ Baseline Blue is intended for connection at the amplifier terminals, and is not always the suggested/recommended solution even by REL.

Right, the Naim version of Bassline Blue is intended for amp connection, but one can use the regular non-Naim Bassline Blue for speaker connection in any case.

For REL six-pack arrays REL also makes Bassline Blue versions of the daisy connectors, but they arenā€™t cheap either.

For a stereo pair of subs, REL says connecting at the speaker terminals is better, because then the subs see exactly the same signal the speakers see, with the character of the speaker cables added. John Hunter has a YouTube about this and says itā€™s a bit of an upgrade to do so.

Look for ā€œConnecting a REL high level to your speakers instead of the amplifier & why itā€™s an upgradeā€

Then you donā€™t need the Naim Bassline Blue. A regular Bassline Blue (or the original REL cable) will do.

The bassline blue for Naim, as clearly stated on Rel website, features a stackable banana plug. So you connect this cable to the amp speaker out and then you connect your speaker cable to the rear of the bassline plug. Thereā€™s no caution against the use of this on Naim amp.

The REL website is a word saladā€¦

Indeed

36

There wouldnā€™t be: itā€™s designed specifically to allow you to connect to a Naim amp if you want to.

I would like connect to the speakers not the amp

38

For a stereo pair of REL subs/arrays thatā€™s the preferred way to do it.

One additional point. I use a single Rel s510 with an olive 250 amp into Quad 2805s. I connect with the bassline blue for Naim cable from Rel. I wired from the amp. There was a small amount of hum. You could not hear it from the listening position but you could hear it with your ear right at the speaker. My dealer solved the problem by grounding the Rel at the phono ground on my olive 72 preamp. Now itā€™s dead quiet and sounds better also.

Rel has subsequently put out a video on YouTube advocating this way of grounding in all situations.

Note that this isnā€™t necessary for all Rels. My dealer said the 812 has no hum at all. However with Quads they prefer the 510.
