Supernait 2 sub out voltage

Hi [@mention:65484947118269668]. If I'm right, the subwoofer output is basically a pre out, so I'd have thought it would be a little less than 1 volt. I may be corrected 

Thanks for that.

I've just noticed that I put the post in the wrong section so could a moderator please move it to hifi corner.

Many Thanks

I'm pretty sure you can just set the sub up and adjust it after you've connected it to get it sounding right. I believe it also has a high level input to connect to your speaker terminals, which is what I do with my N-Sub. There should be a cable supplied with it for this, give it a try and see which you prefer.

Hi Pedropete, I use 2 JL Fathoms in stereo, which don't have a sensitivity setting but, as Chrissu suggest above, I just connected them and set them up by ear for what sounds good to me at the listening position. Ultimately that was best, because most of my measured setups I didn't enjoy. They seemed bland. Everyone wants more or less of this or that anyway, so its personal. Is your sub centered between the speakers? When I used one sub, I centered it. I found it played high enough in the frequency range that no matter where I had it crossed over it gave the music more weight on one side from the listening position unless it was centered. That's how I ultimately ended up with two.

To dial mine in, I first set something playing that had a steady beat and bass rhythm so I was getting repetitive base notes and then I upped the crossover point until I heard overlap with the main speakers and backed off a notch or two. That got me in the ballpark on the crossover. I ended up crossed over higher than I expected. Then I adjusted volume until it sounded right from the listening position. In your case you have the input sensitivity to fiddle with, which I would leave at default to start with or perhaps a touch high. If you have trouble bringing the volume down, go lower with it. Or just experiment - set it at both extremes to see what it does.

Crossover and volume and location in the room are initially the most important. Once you get those basics approximately set, you can experiment with any other available parameter like Q and so forth to see what effect they have. It depends on your room and your taste in bass. I like the fact that you can tweak things one way or the other as needed for each set of speakers.

Whenever I've had to dial in a sub I had to be patient and listen from the listening chair as I went so I'd hear the effects of each change. I just made a change, chilled out a bit and listened to some music for a little while to see what various recordings sounded like. I found that if I fixate on subs, or even on bass in general, it never sounds right. It is like staring at a human nose. The longer you stare at it the weirder it looks.

Good luck man, that's a nice sub.

I have a single JL subwoofer and use the subwoofer output from my SN2.  Do get a decently shielded cable; the loaner I had from my dealer picked up Russian language radio!  Here in the States! (Probably a local low-power station.)

My sub is located just to the left of my left speaker, between it and my Fraim.  I have played with the settings and truly can close my eyes and NOT place its location.  I'm quite sensitive to 'lagging' subwoofer bass, but am very pleased at how well mine integrates into the soundstage.  I do keep its volume set pretty low; I want just that little bit....and I have the high-frequency cutoff relatively low I think.  Too much mid and you'll start to hear it for sure.

Thanks for the replies,

I'm probably just trying to satisfy the old OCD. The sub is between the speakers, next to the right one and I believe it to be set up pretty much optimally but that doesn't stop me fiddling. Don't even ask about the main speaker positioning as I've had them for many years and still moving them 1 or 2cm on a regular basis.

I think the sub is set up pretty much optimally but was reading the manual yesterday (bad idea) where I found the input sensitivity setting which gives me 3 options, -6dB, 0, +6dB depending on whether it's receiving a 2, 1 or 0.5V signal. It's been set at the default 0dB since I've had it. Since I didn't know the sub out voltage I tried the 2V setting of -6dB and as the manual states I then adjusted the sub main gain by +6dB to compensate. I was thinking that -6dB on input and +6dB on output would equal 0dB change and would have no effect but this proved to be wrong. With the new settings, the bass became tighter and kick drums were louder but this came at the expense of other bass sounds being less full. Too be honest I don't know which I prefer so was looking for the sub out voltage so I could set the PV1D to manufacturers recommendation and then forget about it.

In response to Bart, I'm now on my third set of subwoofer cables. I've tried two silver plated copper ones which were heavily shielded and neither of these helped with the integration. I'm now using a cheaper OFC cable with a single shield which is a better match, probably down to the fact I'm using other copper cables elsewhere in the system (Lavender interconnect and NACA5).

I also wouldn't mind giving the high level connection a try but the supplied cable has all four cores insulated together so I'd have to cut off all the insulation in order to connect the wires at speaker end as Naim recommends. This was the reason for making the subwoofer change as my old PV1 had the high level wires pushed into the amplifier speaker outputs.

My bass is now much fuller and tighter than when using the old PV1 but I'm not sure how much this has to do with the sub or connection method. The sensitivity is now back to the 1V setting as I read on another post that most Naim pre's are 0.775V which agrees with Finkfans response so my tweeking is over for now. Well for a few days anyway...
