I know the situation Albin mentions. for example, it is about a short-term failure of the power supply.
I pointed this out a long time ago.
In my opinion, the problem lies in the fact that the preamps get a very high sensitivity for a moment when the phantom power is switched on again. it’s very short, so the feedback is very short. but it can be very annoying.
the better method has to be: mute the INPUTS for a moment; -)
it would therefore be very helpful if the time to unlock would be a little longer, so that the circuits can adjust themselves accordingly.
