I really need an owners manual for a Soundcraftsmen Pro Control 4. Can anyone point me in the right dirrection to get one? I will take an original or copy. I tried that one web site sterio manuals.com and they didn't have anything. I also asked this guy on ebay that is selling one for parts, and he said no. I don't know what to do but I really need one or maybe can someone tell how to bridge amps with this pre-amp?
