Modifications - Mackie 1402 VLZ Owner's Manual

MODIFICATIONS

For most folks, the MS1402-VLZ works just
fine the way it is. But for special applications,
there are three signal routing changes that can
be performed easily on the MS1402-VLZ. Easy
for someone with soldering experience, that is.
If you don't know how to solder, find a techni-
cian that can. This is NOT a good place to learn!
• Modification A changes AUX SEND 2 to be
pre-fader, pre-mute instead of post-fader,
post-mute.
• Mod B changes AUX SEND 1 (in post
mode) and AUX SEND 2 to receive signal
regardless of the channel's MUTE/ALT
switch position, but still be post-fader
(GAIN knob).
• Mod C changes the SOURCE matrix's
MAIN MIX selection to tap the stereo
signal before the MAIN MIX level control
(pre) instead of after (post).

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.
