Default REL Carbon Special

I took the plunge and ordered 2 RELs Carbon Special

I plan to follow REL's instructions of hooking these up via High Level Input to each of the MC611s, and XLR LFE input to the 2 Marantz 8805 sub outs.

Does any of you have similar hook up in their system with the Carbon Special who can share their insights (Dos / Donts)?

I reached out to McIntosh (Chuck Hinton) and he initially recommended to hook up the REL via Low Level RCA inputs to the preamp variable outs and did not recommend using the speaker level connection on MC611. I then sent him the note published by REL on the preferred method of connecting to monoblocs using high level input, and he replied in his email that either approach is ok, and it's up to me to decide.

I wonder if anyone of you have first hand experience on either approach, and what is the best way to connect the RELs to the MC611s and 8805A surround processor. Any guidance is much appreciated

Many thanks.

Hi, you'll be very pleased with your new pair!
The most important upgrade of our system we made the last years.

For stereo, the high level input is preferred. That is what our dealer suggested (and he's REL's favourite dealer of my country). I was surprised that we only had to dial the volume at +/- 25%. I think we ended at about 35-37 Hz.

For surround, we went with RCA-cables from our Marantz 8802A sub outs.

It's all working very well, you don't hear the subs (until you turn them off!), you just feel them (at high volumes).

Good luck!


PS. There was only one negative: we had to wait 4 months...

Excellent choice. I have a single Carbon Special, also connected via high level from my D’Agostino Momentum S250. This is my 6th REL over the years, with a variety of amps, and I’ve always used the high level inputs except for surround use, then low level from the theatre processor.

Thank you Tony and Bart.

and thanks for confirming that you are hooking these up via High level cables. I can't wait and hope it will arrive next week. It will be a fantastic Christmas

Hi Antonmb
I am a UK owner of a stereo pair of REL G2 subs, which I have used with both my CJ Premier 350SA power amp and my TAD M2500MKII power amp (each had to be connected differently, via the high level method, from the speaker outputs.
I have just bought a D'Agostino HD preamp and S250 MxV power amp and as you are also a user of REL subs with an S250 power amp, it would be very interesting to see a photo of how you connect the high level cable from the amp speaker terminals to the REL sub.
Thanks
Steve

Hi XCop - sorry for the delay but I haven't been back to this thread in a while and I just saw your post. Unfortunately I can't show you any pics since I no longer have the sub (changed my speakers and determined that I no longer was benefiting from it). I can tell you that I did nothing special, just had spade connectors on the ends of the REL cable and added them to the amp posts with my speaker cables. Since the D'Ag is balanced, I floated the ground cable.

Ditto. 2 different sets of RELs with high level inputs. Not with McIntosh amplifiers, but great results (and super easy to dial in).

I’m just trying to learn more about REL. the idea of the 6 pack intrigues me.

So - from what I gather on this thread, you connect REL sub with a small wire that comes off your amp (while your speaker cables also go from the amp to the mains-

And then you connect either RCA or XLR from your video processor at the same time?

In other words, when listening in two channel, the subs are activated from the high level, but then when watching a movie, they play from the LFE out on your processor?
