Hey everyone. I bought a secondhand mixing desk from a studio that was closing down. Great condition, no paperwork, and the previous owner had no idea where the manual went. There are a couple of routing options on it that I cannot work out by trial and error, and I would rather not guess with signal paths. Is there anywhere reliable to get documentation for audio gear that is maybe fifteen years old, or am I stuck asking on forums? It is a well known brand, analogue rather than digital, and everything else on it works fine.
