I tried to find some info on the auto bridging but no luck. What worries me "bridging" means to make an amp mono. One thread I found led me to believe that feature requires an additional module but couldn't be sure. If the preamp has a regular output you might try it to see if any difference. From comments I found it does seem the Soundcraftsmen are decent, your EQ should also have some type of lighting system which helps not to overdrive or clip your amps. Another guy mentioned the phono stage was a weak point, saying it was harsh. Keep in mind these are comments from other forums.
