Dear Forum,
the upper mentioned Mic-preamp has an overload-LED built in on the front-panel but this is not connected with the circuit. It's directly connected to the plug on the back-side. So the overload-detection has to be done outside of the unit. Now I found a little pcb wich seems to perform exactly this job. It's called 'U411A'. Anyone ever heard of this? I tried to Behringerize the circuit, since Neumann don't have any schematics left for their Mixer-Modules.
The schematic I have done is under >>> removed <<<
Could this one be an overload-detection-circuit? And if so, can anyone find mistakes in my schematics? (The pcb is very tiny, so quite difficult to Behringerize).
And, if my guess is right, it might be interesting to V476B-owners.
regards
