[. . . ] 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. Mackie Disclaimer Any modification of any Mackie Designs product must be performed by a competent electronic technician. Mackie Designs 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. In the case of such damages, Mackie Designs may declare warranty privileges void. BE CAREFUL! A Note About Jumpers 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. Jumper BEFORE Holes AFTER Solder 26 1. PRE-FADER MOD (AUX TO MONITOR) This modification changes AUX SEND 2 to be pre-fader, pre-mute instead of post-fader, post-mute. ("Mute" refers to the channel's MUTE/ALT 3­4 switch. ) In order to convert the entire mixer, it must be done on each channel, and is slightly more involved for the stereo channels 7­14. The work area is on the underside of the circuit board, near the channel AUX SEND knobs. Remove all cords, including the power cable, from the MS1402-VLZ. Place the mixer upside-down on a dry, non-marring surface. Remove the screws that attach the bottom cover. Using a sharp "X-acto" type knife, cut the conductor at point `A' (channels 1­6) or the conductors at points `AL' and `AR' (channels 7­14). Be careful to cut all the way through the conductor, and do not cut any nearby traces. Add a jumper from point `B' to the square pad at point `A' (channels 1­6) or from points `BL' to `AL' and `BR' to `AR' (channels 7­14). Check your work very carefully, then put the bottom cover back the way you found it. You're done!

PRE-MUTE MOD This modification changes AUX SEND 1 (in post mode) and AUX SEND 2 to receive signal regardless of the channel's MUTE/ALT 3­4 switch position, but still be post-fader. In order to convert the entire mixer, it must be done on each channel, and is slightly more involved for the stereo channels 7­14. The work area is on the underside of the circuit board, near the channel MUTE/ALT 3­4 switches. Remove all cords, including the power cable, from the MS1402-VLZ. [. . . ] If you carry enough equipment that you need to wire directly into the electrical service, then use a voltmeter to ensure that the line voltage is correct, then use the outlet tester mentioned in #3, above. Do this before you connect any of your audio equipment. Chances are that your 120V gear won't be too happy if it sees 220V for any length of time. Cables that are too long are less likely to pick up hum if you uncoil them in their entirety, and then find a place to stow the excess. [. . . ]
