I could do with some help please. I’m pulling my hair out.
I’ve just changed my 282/250 to a NAC252/non-Naim PS/500. I spent the w/e taking my rack apart to get everything in place and now I have two problems.
Neither the volume button nor the balance button on the 252 turn with the remote. Changing batteries has not helped. In my effort to get AV bypass working I wonder if by playing around I’ve got the 252 in the wrong mode, if there is such a thing? I reset the 252 back to default settings but no change.
My right channel is not working. I’ve switched speaker cabling and ruled out the speakers/speaker cables. I’ve unplugged all the 500/PS cables and plugged in again to no avail. I have tried two different sets of cables from the 500 to the SC. I’m sure I have the 500 cables all where they should be. However, both speakers work when I pres MON on the 252. At first I thought MON meant monitor and this was a sign that the 500 was ok and the issue was restricted to the 252. Now I understand MON is short for MONO and I’m wondering if pressing MON is just sent the same left channel signal to both speakers?
One more thing, when I turn the balance all the way to the right and the volume right up to maximum I can hear the right channel speaker. Very much reduced volume but sound nonetheless. This is without the MON button engaged.
The first thing to check is that you have the cables between the Supercap and 500 the right way round. It doesn’t matter at the SC end, but the cable with red marker absolutely must go into the right /ch2 socket on the 500.
I do hope it’s the 252, rather than the 500 as the 252 is still under warranty.
I’ve just tried it on a couple of tracks where I know different sounds come from left/right and it sounds to me like the MON button is sending the same signal to both speakers. What that means after that I’m not sure! If I’m getting any sound at all out of the right channel surely means the 500 is not the culprit?
Get the manual or book out for the 252. Get everything back to factory and go from there. The lack of switching and volume pot not moving suggests an issue with the " napsc" bit of the SC. However does explain the lack of noise, hence get 252 back to factory.
If you had another SC to try, id suggest that, but i get that is highly unlikely.
Did you use the non-Naim PSU with the 282? And a NAPSC with the 282? If so is it possible that the Supercap worked with the 282 but given the different supply connections with the 252 it is showing a fault that wasn’t obvious with the 282. Can you take the 252 back to the dealer to check with a Naim Supercap?
Be sure to actually swap the XLRs around on the 500 in case they are the stereo version of the cables and not the usual mono ones for the 500 (or 300).
The other thing is send us pics of connections on back of units if possible. We are all saying to check connections. I believe it is something to do with that. You have a non Naim Supercap and therefore connections may look slightly different from the manual.
