Yesterday I bought a 300 and connected it to the 222.
At first I would have wondered why the NPX does not turn on the 222.
The “Naim” light on the 222 does not light up, only the display is activated. Neither the app nor the remote control works, and the volume control doesn’t get its white light either.
It works again immediately as soon as the 222 is operated alone again, so with the two plugs and its own power supply.
Can you share a clear photo of the back showing both the connections on the 300 and 222?
For nearly all Naim kit behaving weird with an external power supply it is either a loose connection or a missed secondary connection (for units that require it) or a blanking plug in the wrong place.
Have you connected both Burndy leads correctly? If you have, and disconnected the mains from the 222, it’s likely that your 300 or its burndies are faulty. If it’s new, your dealer is your first port of call.
All NC kit has a logo light brightness reset button on the back, so it should just be a question of using that to get it to come on.
I see that you have your NPX300 Power supply on the top of your rack, perhaps without it, that was the empty shelf? Nevertheless, putting the PS above the preamp in the 222 may not be a good idea. Can I suggest, even though it’s a big job, that you rebuild the system in the usual configuration with preamp at the top? It may just help your connection issue, but if it doesn’t then get your dealer to provide help in the form of new cables, or a new unit.
PS: After I connected the 222 solo again, I noticed that a noise is now coming from the speakers and a quiet “tacking” can be heard in the left channel even though the volume is 0.
If problems with too tight Burndys I recommend this one and to remove the rubber strap, wrap it around the metal part on the Burndy and gently turn by hand (not using the handle). It makes it sooo much easier.
My system now works again as before, so the 222 with 250.
I don’t know if I’ve never noticed it before, but when I turn on the 250, I don’t hear any noise from the speakers, etc. When the 222 is added, it’s just turned on, no matter which input, I always have a background noise in the speakers.
I’m not sure if this was already the case before connecting the 300 and I just didn’t notice it… Maybe one of you will try it out to see if it’s the case.
