REPAIR
Service for the 24•4-VLZ PRO and the
32•4-VLZ PRO is available at our factory, lo-
cated in sunny Woodinville, Washington.
Service for Mackie 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.
2. Call Tech Support at 1-800-898-3211, 7 am
to 5 pm PST, to explain the problem and
request an RA (Return Authorization)
number. Have your mixer’s serial number
ready.
You must have an RA number before you
can obtain service at the factory.
3. Keep this owner’s manual. We don’t need it
to repair the mixer.
4.
Very Important:
Move all Faders to their
UP position as this will help prevent
damage to the faders during shipping.
5. 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 new packaging.
Mackie is not
responsible for any damage that occurs
due to non-factory packaging.
6. Include a legible note stating your name,
shipping address (no P.O. boxes), daytime
phone number, RA number, and a detailed
description of the problem, including how
we can duplicate it.
7. Write the RA number in
BIG PRINT
on
top of the box.
8. Ship the mixer to us. We suggest insurance
for all forms of cartage. Ship to this
address:

9. Ask Tech Support for the latest turn-
around times when you call for your RA
number. We normally send everything back
prepaid using three-day shipping. However,
if you rush your mixer to us by next day air,
we’ll treat it in kind by shipping it back the
same way in which it was received. This
paragraph does not necessarily apply to
non-warranty service.
TROUBLESHOOTING
If you think your Mackie product 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. Here’s a few troubleshoot-
ing suggestions:
No channel signal
•
Is the 1-2 & 3-4 (40) or L-R (41) switch set
correctly?
•
Is the CHANNEL FADER (42) turned up?
•
Try soloing that channel. Does it appear on
the METERS (54)?
•
On mono channels, try unplugging any
INSERT (3) effects devices.
•
Try the same signal in another channel, set
up exactly like the suspect channel.
No Output
•
Are the L/R ASSIGN (59) switches set
correctly?
•
Are the MAIN MIX FADER (72) or SUB-
GROUP FADERs (60) turned up?
•
Try unplugging any insert (7) (13) effects
devices.
•
If it’s one of the MAIN OUTS (12) (16), try
unplugging the other. For example, if it’s
the MAIN OUTS (TRS) (12), unplug the
associated MAIN OUT (XLR) (16) output.
If the problem goes away, it’s not the mixer.
•
If it’s one bad side of a stereo pair, try switch-
ing 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 side, it’s not the mixer.
Noise
•
Turn the CHANNEL FADERs (42) and
STEREO AUX RETURNS (48) down, one
by one. If the sound disappears, it’s either
that channel or whatever is plugged into it,
so unplug whatever that is. If the noise
disappears, it’s from your whatever.
Power
•
Our favorite question: Is the POWER (20)
switch on?
•
Turn off the power from the wall, unplug
the power cord and check the fuse (22).
