1604-VLZ Auxiliary modifications
In addition to the modifications shown in the 1604-VLZ owner’s manual, there are two
rather lovely and optional mods for the signal routing of Aux 3/4 and 5/6.
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!
About Jumpers
We recommend solid (non-stranded) insulated wire, 26–28 gauge (wire-wrapping variety). 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.
Tools required
Sharp razor (X-acto) knife, soldering iron, solder, Phillips screwdriver.
Getting ready
The 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 correct operation, making especially sure that all modified channels are working correctly.
