I received a Naim MUSO 1 on Friday, August 15, 2025. When I received it, it worked normally. After connecting to the internet, it went into an infinite loop and suddenly stopped, and the power button kept flashing. When I pressed the power button, the loop returned, then stopped, and the power button kept flashing. It’s been like this for four days now, and I can’t hear music.
When it’s in loop, it connects to Bluetooth, but there’s no sound.
When the power appears, it disconnects from Bluetooth.
It’s probably trying to update itself, as it has found the last update firmware available over the air; connect to your router via an Ethernet cable, and perform a hard reset.
Connect to internet using a cable and then perform a hard reset. If the muso is like the qb it has a small whole with a button you need to press for a few seconds to hard reset the unit.
In this way you get rid of the previous owners settings.
Three times I turned on the generation one mu-so with the reset button driven for 10 seconds, with the blue LED on and six strokes stopped around the rotating disc.
Once it took five hours, sometimes four hours and once again four hours.
But I was unsuccessful in any of these attempts.
And when I turn on without pressing the reset button, I light up three strokes, then a dash on the rotating disc and have a red LED.
Before making the reset the bluetooth appeared now no longer appears.
Note: I live in Brazil and in the state where I live, no assistance for this equipment.
I gained this equipment by performing services on a customer.
If you mean a forced reset didn’t work I’d say it’s time to contact Naim’s service department and see what other options you might have. Here’s their email address and phone number: support@naimaudio.com / 01722443405
