When I joined my church choir in 2006, we had an unnecessarily elaborate sound system, including "rock star" solo mics for every individual chorister and a 24-channel mixer that nobody knew how to use. By 2010 we'd updated it to a correctly sized system with a more modest mixer that nobody knew how to use, either. Therefore, I took it upon myself to search by model number, print out a pair of copies of the comprehensive user manual, and then I tucked one of them snugly into the rack mount for reference by any current and future directors.
