I suspect I know the answer to this question already(send it back to Naim) but I’m getting an error on my NDX screen telling me there are two PSUs attached. Disconnect and wait 10 minutes.
Is the blanking plug for the external PSU likely to be the error, a sensing board error or who knows ? !
Everything is securely plugged in. It works for a while after powering off.
Just wondering if anyone else has experienced this ?
I suspect the blanking plug needs pulling in and out a few times to clean the contacts. As you aren’t using an external supply, the NDX is perhaps sensing that you still have the internal supply working when the absence of volts elsewhere means you must have an external supply. Or something like that.
I had a similar issue with a ND5-XS (1st gen) and after trying a replacement blanking plug, ended up sending it back to Naim for a new power board (out of warranty).
