Service Info - Mackie 1402 VLZ Owner's Manual

SERVICE INFO

Details concerning Warranty Service are
spelled out on the Warranty Card included
with your mixer (if it's missing, let us know
and we'll rush one to you).
If you think your MS1402-VLZ has a prob-
lem, please do everything you can to confirm it
before calling for service. Doing so might save
you from the deprivation of your mixer and the
associated suffering.
Of all Mackie products returned for service
(which is hardly any at all), roughly 50% are
coded "CND" — Could Not Duplicate, which
usually means the problem lay somewhere
other than the mixer. These may sound obvi-
ous to you, but here's some things you can
check:
TROUBLESHOOTING
Bad Channel
• Is the MUTE/ALT 3–4 switch in the
correct position?
• Is the fader turned up?
• Try unplugging any INSERT devices
(Channels 1–6 only).
• Try the same source signal in another
channel, set up exactly like the
suspect channel.
Bad Output
• Is the associated level control (if any)
turned up?
• If it's one of the Main outputs, try unplug-
ging all the others. For example, if it's the
1 ⁄ " Left Main out, unplug the RCA and XLR
4
Left outputs. If the problem goes away its
not the mixer.
• If it's a stereo pair, try switching them
around. For example, if a left output is
presumed dead, switch the left and right
cords, at the mixer end. If the problem
stays on the left it's not the mixer.
Noise
• Turn the channel fader and AUX
RETURN knobs down, one by one. If the
sound disappears, it's either that chan-
nel or whatever is plugged into it, so
unplug whatever that is. If the noise
disappears, it's from your whatever.
34
Power
• Our favorite question: Is the POWER
switch on?
• Check the fuse .
REPAIR
Service for the U.S. version of the MS1402-
VLZ is available only from Mackie Designs,
located in sunny Woodinville, Washington.
(Service for mixers living outside the United
States can be obtained through local dealers
or distributors.) If your mixer needs service,
follow these instructions:
1. Review the preceding troubleshooting
suggestions. Please.

may refuse the delivery.

or anything else that you'll ever want to see
again. We are responsible for the return of
the mixer only.
4. Pack the mixer in its original package,
including endcaps and box. This is VERY
IMPORTANT. When you call for the RA
number, please let Tech Support know if
you need a new box.

phone number, RA number and a detailed
description of the problem, including how
we can duplicate it.
