Mackie Compact Mixers Modifications General Notes about Modifications We've tried to make these mixers as universal as possible, but you can't please everyone all the time. For certain applications, you may find these signal routing changes beneficial. They're easy to make if you have experience soldering and working on electronic equipment, but if you don't have the experience, this is NOT a good place to learn. Take your mixer and this book to a qualified technician. Here are the obligatory warnings and disclaimers that our lawyers made us include. We think it's a good idea to heed them (the warnings, not the lawyers), too. About Jumpers These modifications involve cutting traces on the circuit board and installing jumpers between pads. We recommend solid (nonstranded) wire, 26-28 gauge. The type of wire used for wire-wrapping is easy to form, lays neatly against the circuit board, and has insulation that doesn't melt easily from the heat of a soldering iron. When installing jumpers, do not run their ends through holes in the circuit board. Rather, solder them flat against the desired pad (the flat silver area, possibly with a hole in the middle). Make sure the ends of these flat wires do not extend beyond the pad. BEFORE Jumper Caution! These modification instructions are for use by qualified personnel only. To avoid electric shock, do not perform any servicing other than changing the fuse unless you are qualified to do so. Refer all servicing and modifying to qualified personnel.

LOUD Technologies accepts no responsibility for any damages or injuries caused by any modification, regardless of the source of the modification instructions or the qualifications of the technician performing them.
