The AM can use both left and right channels and, or so it seems, so can the Devialet output both, one from each monoblock. Anyway, we’d need someone who has tried to confirm. Also I forgot to mention it earlier, the exact frequency is point of debate among experts but roughly sound below 80Hz or so is unidirectional so it doesn’t matter much if you apply crossover filtering at or below that frequency. Enjoy!

Today, I was at the REL dealer for over 5 hours. At first, I heard the No.25 followed by the S-series 212/SE and finally the G1 MK II. The No. 25 is outstanding but waaayy too big for my very difficult 'square 18-Ft x 18-Ft dedicated room'. And, I wasn't impressed with the 212/SE but the G1 MKII completely floored me. It was devastatingly good and was mated to Wilson Sasha DAWs that I auditioned. I heard classical, organ, opera, smooth jazz, 60's, 70's & 80's rock and was awestruck at what a pair of G1 MKIIs were doing to the overall sonic experience. They sell in the US for $ 5,500 each, meaning $ 11,000 + taxes for a pair. It is indeed a lot of money but I also realise that this would be the single 'massive upgrade' I can do to my existing system and can also sell off the 2nd 440-Pro set and revert to bi-wiring from bi-amping. Hmm! I will have to start saving up of this now ... a pair of G1 MKII when setup right using the High Level input of the Devialet is soooo addictive !!

Where the G's you auditioned connected to high level from a Devialet?

Lol oh dear I feel somewhat responsible I'm glad you experienced the revelation that adding the G1 Mk2s brings! Your problem with the 212/SE was that you listened to them second after the No25 (which I agree are amazing but way too big for a stereo pair setup for most people) so they were always going to sound mediocre. I've heard the G1 Mk2 described as a mini No25 and I think that sounds about right. I'm still in awe of the extra dimension these bring to my system although we are still trying to get to the bottom of the electrical hum that one of mine has. Mr REL is coming back to swap the amp board in one of them as it seems to be that one sub that is causing the issue but so far 10/10 for system improvement and 10/10 for REL customer service! I notice on this thread that everyone except me seems to be using or wanting to use the high level input, I asked Mr REL about this last time he was round at my house and was of the opinion that it makes no difference at the sub end and that the Devialets are so good it doesn't matter which you use. For me I'm using SAM on my speakers so high level is not a good idea plus it gives me control to turn the subs on and off if I need to. So the question is has anyone actually tried high vs low level connection and noticed a difference?

The range of the Futura is down to 25Hz, the REL is connected via HL cables and is set to start the range at 26Hz down to 15Hz. The result is amazing. Bass are define, sharp and fast, no comparison with any other Sub I heard. To the point that is a bit of a show stealer. I had people coming to check my system and forgetting Devialet, SF, and all the rest and pretty much only commenting on the incredible quality and precision of the bass, such is a stark difference of what you usually hear. Could you please let me know if the BLACK wire of the HL is left taped off or attached to the Ground post just below the Phono RCAs ? I am considering G1 MK II Pair and plan to use HL.

Hello, The black wire is connected to the black output of the left speaker. The red one to the red of the left speaker The yellow one to the red of the right speaker. This is the set up that the guy who installed did and I never had humming issues. Hope it helps Marco RE: Dual mono with REL Subwoofer - audio_engr - 12-Jun-2019 (12-Jun-2019, 11:12)marcor Wrote:(12-Jun-2019, 06:04)audio_engr Wrote:(14-Apr-2019, 22:55)marcor Wrote: For what it worth, I have a G1 MK II connected to my Devialet Expert Pro 250 to complement my SF Amati Futura.

This is a very interesting answer. According to REL, they have a wiring scheme for Class A/AB amps and a different scheme for Class D amps where the Black wire is not grounded. As per your response, with the Black wire connected on Left speaker -ve (black) terminal, this is a typical Class A/AB scheme of wiring. Is REL treating the Devialet as a Class A/AB amp and NOT Class D ?? RE: Dual mono with REL Subwoofer - JohnnySix - 12-Jun-2019 I have read that Devialets behave like classic amps with regard to Ground vs -15v issue. I once had a Rotel Class D that frightened the life out of me when I connected a Rel High Level! On the subject of Hum, I’ve found that the 2nd hand T7i I got from Nintronics has a mild hum, but my original T7i has none. PHASE: Having spent weeks measuring the effect of Devialet delay values on sub integration using wavelet spectrograms, I’d beware the suggestion to turn on high pass filter for the mains. It can introduce a significant phase shift that could upset a professional's installation. But provided you can measure and compensate for it, it CAN reduce over-thick bass in the crossover region.

I once had a Rotel Class D that frightened the life out of me when I connected a Rel High Level! Thanks for your response & recommendations. Anyway, so long possible, I'd go with High-Level setup of the RELs. REL G1 MK II designer John Hunter tells me its much more dynamic and much superior integration with the Main speakers than using Low-level. I am only concerned that it seems the Black (ground) wire also needs to be connected in this case with Devialets. Just hope it doesn't mess up the Amps or my main speakers ... |
