[. . . ] 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 1­4) or from points `BL' to `AL' and `BR' to `AR' (channels 5­12). Check your work very carefully, then put the bottom cover back the way you found it. You're done! JUMPERS UL Warning 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. 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! JUMPERS JUMPERS JUMPERS JUMPERS CUT CUT CUT CUT CUT CUT #1: Pre-Fader Mod 26 2. 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 3-4 switch position, but still be post-fader (GAIN knob). In order to convert the entire mixer, it must be done on each channel. It is slightly more involved for the stereo channels 5 through 12. The work area is on the underside of the circuit board, near the channel MUTE/ ALT 3-4 switches. Remove all cords, including the power cable, from the 1202-VLZ PRO. 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 `C' (channels 1­4) or the conductors at points `CL' and `CR' (channels 5­12). Be careful to cut all the way through the conductor, and do not cut any nearby traces. Locate the 12 pins that comprise the underside of each MUTE/ALT 3-4 switch. Add jumpers as shown on the illustration below -- they're not marked on the circuit board itself, so be careful. Check your work very carefully, then put the bottom cover back the way you found it. [. . . ] 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. Leaving the excess coiled only helps the cable pick up hum more efficiently. Don't run unbalanced lines to or from the stage. [. . . ]
