I just read in an ad for one that you should only use polyester based sound films, since acetate based films will emit a high-pitched squealing sound. It can be used with polyester or acetate silent films, however.
Anyone know why? Is this the only Beaulieu model for which this rule applies?
I've had projectors emit a high-pitched squeal, and the solution was cleaning all the sound-related parts with contact cleaner. Worked like a charm.
