Billy Boy, yes the spec sheet is from the jobsite, not the manufacturer. Congrats for guessing that correct. The 12db is the input level the system demands at the input of High Gain Duels. So what the means Billy Boy, is you have to change your mid stage pad to have the proper output levels, and this WRONG. As you have been told before, the mid stage pad, eq, and output pads have been selected for that particular module to achive optimal performance. Got a hint for you Billy Boy, do as Drifterdawg suggested. Call The good people at SA. They will answer your questions. Well they will answer your questions if they don't laugh you off the phone first. For gods sake get a clue, and grow up. In the meantime why don't you go play in the traffic.
