NAC282 and power supplies

Nothing.

The NAC282 would replace the NAC112. As you say the Napsc that comes with the 282 and it would supply its power to the 282's specific Napsc socket. One of the outputs of the Flatcap would also supply the 282 on one of its 'upgrade' sockets. And the FC would connect to your NAP150, as it does now.

If your sources are up to it, this should be a pretty stonking upgrade.

Thanks, but would I need the NAPSC? Could I use the second Flatcap feed?

I don't think the Flatcap powers the NAP

You would need the NAPSC (along of course with tthe 282) - and you would use the NAPSC even if you were using a Supercap to power the 282. But the NAPSC comes with the 282 as part of the package - or at least it should do. 

I see, much appreciated.

Yes, you'd need the Napsc. You probably could use the second FC feed on the 282 but it would need a Forum Greybeard, or Naim, to confirm it.

Quite right. You will need to connect it to the NAP though, as I said.

So I could lose the Flatcap to help pay for a 282?

Yes you could. You'll raise all of tuppence, you might as well keep it. It will do a better job than the NAP150.

I ran a very similar set up to this (except with a hicap instead of the flatcap) and it sounded great. The 150 struggled with my speakers though as my Neats at the time were hard to drive. But then I swapped the 150 for a 250.2 and then the whole system ( now with an NDX front end) started sounding right....

FYI, the NAPSC powers just the digital control circuits of the 282. The purpose is to separate the feed to those noisier circuits from the feed to the signal circuits from your other power supply such as Flatcap, Hicap or supercap.

I ran my 282 from a flatcap 2x for a couple of years. I prefered the more defuse but larger scale of using just one output to the more precise but smaller scale image obtained using both outputs of the fc for the 282. When I eventually got a Hicap (every time I went to order one I got distracted, first by an ex demo superline, which I powered from the aux2 socket of the fc powered 282 incidently, and the second time by a lightly used aro) the sound relaxed a bit and gained in gravitas. You can order a new 282 without a psc I think, if you already have one but it won't work without and it's included by default. It sounds like your buying 2nd hand so if there's no psc the seller is pulling a fast one. My power amp at the time was a rega maia so I couldn't compare to powering the 282 from a power amp.

With a NAC282 it's better to lose the Flatcap to help pay for the Hicap...

Thanks again.

I'm not planning on anything at the moment, just trying to understand how it all fits together. I was confused as the NAPSC is optional for the 282.

I presume it is mandatory for the 252 as well.

Sorry I meant optional for the 202

Adam is absolutely spot on.

Only thing to add is - if you buy a used 282, particularly on auction sites, always check and confirm that the NAPSC is included. A new 282 will come supplied with a NAPSC.

Richard,

the 282 can be powered by two HiCaps; the Flatcap has two 24V outputs (if it's a FC2x, IIRC, the two outputs are identical): would it be so silly to try both FC's 24V outputs on the 282 before moving to a HC?

M

I used to connect both outputs of my FC2x with my 282 and to my ears it was a) much better than just using one and b) pretty much the same as using the now "old" HC2 - which I changed to at a later stage. In other words I wouldn't bother getting a HC2, if you have a FC2x already. My advice would be, don't worry about minute differences, go for bigger changes - much better to aim for a HCDR instead. 

Max, not silly, no.  By all means try it. FWIW I felt that a Hicap on the NAC282 was much better than a Flatcap2, however I never tried connecting both supplies from an FC2x or xs.

I wouldn't suggest buying a fc to run a 282 but if you have one with a spare output or two and a 282 comes your way for the right money it will power it well enough to get you started in the absense of a nap with a power out. Compared to a hicap it will sound a little sharp and thin but not unbearably so with a little care in the setup.

In that case there is a possibility for upgrade 1 for hicap and upgrade 2 for flatcap. 

I have a question. Using a 282/NAPSC/SCDR myself, I've often wondered why a SLIC could not be used from the SCDR's 5 pin digital power out to the 282? After all, you can substitute a NAPSC for a HC+SCLIC into a Headline.

I do realise there a 5v difference, but this doesn't seem to be an issue for any component where the SLIC is officially supported. It's something I should know but I've never really thought of it before now. I'm not inclined to experiment though

Slight amendment. NAPSC and digital power out on the SC are both 12v. So assuming a SLIC had the right pin assignments, I wonder why this is not one of the documented connection options?

NAPSC is 18v

FZ, IIRC the NAPSC is 18V and the NAC282 and NAC202 need this for their control panel.  Digital psu output on SC is lower voltage (15v?) and not enough to unmute either.
