Well it has arrived today, what a lovely looking piece of kit.
I will set the Pre-gain to +12 to start with and see how it sounds. Going to leave it powered on for an hour before I listen to it.

One query
In the manual when advising on how to change the gain setting it says
The unit should - but must not - be switched off

A tad confusing does it mean switch it off when changing the settings ? Common sense would point me in this direction.

This sounds like Fried telling you that you should really turn it off before changing the gain settings - but that he probably built in some safety to make sure it doesn't break even if you did change it with the device on.

Maybe something lost in the translation then :relaxed:
I have not touched anything yet as letting it warm up for an hour or so first. I will adjust the settings when it is turned off though.

I typically switch it off.

I am sure it did come form a translation mistake from German to English

muss nicht = does not have to
darf nicht = must not

You are very patient. I just turned it on and off I went :)

Question for users that turn off their Niimbus during the day or overnight say.
I loose my LED brightness and line out settings.
Is this normal ? reading the manual it seems like it should retain them.

Ok I am on +18 gain too to listen at 12 o clock, so yeah I guess I listen too loud too. :relaxed:

What?…🙉
Yeah this is more gain setting than I thought I would use. I had my booster jab yesterday and I do feel a little off colour today so this may explain it.

Do a software reset, then try again

Thanks I have tried that after your suggestion. Everything reset LEDs changed to their normal Luminosity and the line out returned to white.

Setting the LED's to the lowest brightness and the line out to off i then turned off the amp.
The issue persists. Reset again and tried just the LED's and the line out in separate tests and each time after a reboot the settings are lost.
Seems like there is no CR2032 or the like in this unit.

Did you save the settings with pressing XLR for 2s before turning off?

I know this is probably not what you want to hear, but as we got the units at the same time I thought I would test what you have experienced.
I dimmed the lights and slowed down the volume control and they both saved their settings with no issues.
