Has anyone got any experience with a PA? I agreed to do the sound for my uni radio's battle of the bands gig (silly me) expecting them to be running a board with a couple of active monitors... oh no, they're using a XR684 PV PA. The rooms not that big and I think it would be out of our budget/timescale/ability to mic everything and we don't want it deafeningly loud so I'm just going to shove the mics for miscellaneous instruments straight in and maybe use my voicemaster pre on the main vox. Any words of wisdom here?
