[QUOTE="Silas Pradetto, post: 63914, member: 34"] Re: Setting up Aux Subs Only thing I've found that's a little funky is running stereo inputs with aux subs. When I tune my systems, I am usually running a stereo input for music, which essentially means, I have two inputs, each with the same bass signal sent to the subwoofer aux. You could think of this as being twice the power, and seems to cause my sub send to be +3dB hotter than it would be if using a regular single input. So, I often have to adjust my subwoofer balance again during soundcheck. I do not know how or even if different mixers handle aux sends for 'linked' or dedicated 'stereo' inputs differently than 'dual mono' inputs. On my systems, when possible, I use a group for subs so the individual channel subwoofer level cannot be adjusted relative to the others. This keeps my crossover point where I want it to be. (This would only be a problem if the subs/tops were phase aligned over a very small range, and moving the crossover point up or down significantly affected alignment. In most cases, it won't matter.)
