I bought a mixer for $75 while i was on vacation in Newport, Oregon and i dont know anything about it. Its an 8 channel mixer that looks like it is something that would be used mostly for live shows but it doesnt have the power amps or anything just the normal builtin preamps. It says Richmond Sound Design at the top of it and so i looked it up and found nothing for it. Any help would be great. Thanks.
