Neumann KH 750 problem

[Grzegorz Radziejewski]

Hi. I have a problem with my Neumann KH 750. It's stopped working three times now. It doesn't send a signal to the connected monitors. I have the MA1 system calibration set to two KH 310 monitors and one subwoofer. Everything works fine, but then I hear digital signal processing errors from the speakers and there's silence. The LED on the KH 750 remains green. After restarting, it no longer sends a signal. There's silence. After reconfiguring it using the MA-1, the system began to function correctly. However, a few days later, the problem recurred.
The only option is to send it to a repair shop? Sorry for my English, I'm using a translator. Thanks for any suggestions. Best regards, Grzegorz.

Is the unit still under warranty? That rather sounds like a case for Neumann's factory repair service. Their website suggests contacting the local distributor to inquire about servicing options. For Poland, that would be
