I'm proud owner of  a xtm4 issue 3 meters and would love to find matching manual and service manual / tech infos for it please.

I can't setup it to start on xlr analog input mode, cant calibrate the peak meters, there is it seems one ic missing inside and one psu cable is unconnected which is weird.

There is a bunch of trimmers inside and I would love to know how to adjust them in case it is needed.

Thanks a lot and best from south of France

Good day 

Since the XTM-4 was a current product when WBS closed, I'm not sure what happened to the documentation / and schematics when the factory closed.    I do have a manual: https://docs.google.com/document/d/1xK-Me-PWltqF2UD7PaDC7iqZ57ZUzmt-rbsBNluntO4/edit?tab=t.0

However it does not go into the detail that you would need to calibrate.   Maybe @Kevin Lyver can offer a glimpse into his archive to help you out.   He's a very generous contributor and has supported the WBSps from day 1.
