These modification instructions are for use by qualified personnel only. To avoidelectric shock, do not perform any servicing other than changing the fuse unless you arequalified to do so. Refer all servicing and modifying to qualified personnel.Mackie DisclaimerAny modification of any Mackie Designs product must be performed by a competentelectronic technician. Mackie Designs accepts no responsibility for any damages orinjuries caused by any modification, regardless of the source of the modification instruc-tions or the qualifications of the technician performing them. In the case of such dam-ages, Mackie Designs may declare warranty privileges void. BE CAREFUL!About JumpersWe recommend solid (non-stranded) insulated wire, 2628 gauge (wire-wrapping vari-ety). When installing jumpers, do not run their ends through holes in thecircuit board. Rather, solder them flat against the desired pad (the flat silverarea, possibly with a hole in the middle). Make sure the ends of these flatwires do not extend beyond the pad.Tools requiredSharp razor (X-acto) knife, soldering iron, solder, Phillips screwdriver.Getting readyThe following must be performed before starting the actual mods.1. Remove all cords, including the power cable, from the 1604-VLZ.2. Place the mixer upside-down on a dry, non-marring surface.3. If you have converted your mixer to the rack-mount position or have installed a RotoPod,undo those changes and temporarily configure the mixer in the original desktop mode.You do not have to install the pod, just get it out of the way of the bottom cover.4. Remove the screws that attach the bottom cover. Keep track of what screws go where.Remove the bottom cover and have at the mods shown on sheet 2.5. When you have finished the mods, put it all back together and retest all fuctions for cor-rect operation, making especially sure that all modified channels are working correctly.1604-VLZ Aux mod, sheet 1 of 3 Aug 1999? ? ? ? ? ? ? ?To make Aux 3/5 and Aux4/6Pre-EQ and Pre-FaderAux 3/51.
