Hello!
I have successfully used mixer LighMaster XL for 11 years in an Institute for Social Events (Polish: Dom Kultury).
A few weeks ago the analogue component (section) of the mixer broke down (no output voltage of 0-10V).
I have checked the reference voltage on chip ZN439 and it is fine (2.66V).
The battery is working properly as well.
Could you please help me locate (find) the fault/ faulty part of the mixer?
Looking forward to heraing from you!
Best regards
