I'm new to the whole PA stuff and was wondering if anyone knows of a decent PA set up strictly for vocals in a death metal band. Is it possible to hook straight into a PA speaker without the use of a mixer, or will I need a mixer and a speaker? I'm thinking i need a mixer because I don't think PA speakers have volume controls. I'm doing vocals through a 100 watt marshal combo currently and I can hardly hear over my half stack and the drums. Any advice is appreciated thanks.
