Hi everyone. After some techie help if anyone has any insight. SOrry for the long post I’ve tried to include all details:
System: ndx2 with xps, nac252 with supercap, NAP300DR with 300PS, Focal sopra 2, superlumina interconnects and cables where poss, rest are naim out the box (burndys etc).
Issue - only coming out of right channel when sending din out from ndx2 to din ’tuner’input. was working fine the night before, not powered down overnight.
Done:
Switch nac252 to ‘Mon’ - comes out of both speakers (in mono obviously)
Tried different din input on NAC252, still only 1 channel
Tried another device (old school ipod) to AUX2 using RCA, worked in stereo no problems
Changed DIN cable from ndx2 to nac252 to the grey one supplied with ndx2 - still only one channel. So its not the DIN cable
Tried RCA from NDX2 to NAC252 - full stereo no problems.
Did factory reset on ndx2 - didn’t change anything.
Did software reset on NAC 252 (hold display button on remote when in prog mode) - no impact
Full power down for 10 mins - no impact
Conclusion - I think can only be the NDX2 Din output, or something on the NAC252 that says ‘all din inputs just right speaker only’
Its could be a stuck relay. I may be wrong but I seem to recall that @NeilS confirmed the relays were independent between RCA and DIN. I’m sure he can confirm or not when he has a chance to read the thread.
Thanks Dean, sounds like it needs to be returned to naim. Could a stuck relay affect only one speaker do you know? ie is there 1 relay per speaker? Thanks in anticipation, much appreciated
The response ‘it sounds like a stuck relay’ is becoming more like a stuck record. Let’s hope Naim get this sorted out, especially with repairs taking so long. To lose your music for a month or more because of a fault that shouldn’t happen is really not great.
Hi HH. I know, it’s a shame but the silver lining is that I hear the backlog for repairs is cleared and turnaround should only be 2 weeks. If it’s a design fault then like you say, let’s hope it gets sorted! Thanks for your response, much appreciated.
I can confirm that the DIN & RCA outputs have separate single pole relays for each channel (so there are four in total).
So loosing a channel on just one of the outputs is perfectly feasible if one has failed.
Thanks Neil. I’m taking the NDX2 to the dealer tomorrow just to finally rule out any problem with the preamp (which seems highly unlikely), at which point we’ve narrowed it to something in the NDX2 box - sounds like a relay issue. Thanks for responding!
My ndx2 has just arrived back at the dealer from Naim and apparently it wasn’t the output relay, it was the whole analogue board that needed replacing…. Sounds serious! But done under warranty. Just wanted to feed back, thanks for your help and advice folks.
