Manual written by Jeff Gilbert and Dave Franzwa, with tidbits borrowed from almost everywhere, including huge chunks of techni- cally baffling text contributed by Rick Chinn. Manual then defaced with proofreading pens in the hands of Mackie’s legendary Tech Support staff (Paul Larson), New Products Engineering staff (Cal Perkins and Cameron Jones), and our incomparable Art Department (Sara Delahan). Back cover collage composed by Jayme Delma.

Manual composed with No. 4 blue sidewalk chalk on the banks of beautiful Sammamish Slough by Mackie’s notorious Technical Writing staff, then converted to this amazing piece

of work using a 13-story 1000 gigawhat Macintosh, powered by its own dedicated AC supply with extensive voltage regulation and noise filtering to insure pure, undistorted text. Please, feel free to let us know if you find an error or stumble over a confusing paragraph. Thank you for reading the entire manual (we know you have, or you wouldn’t be here).
