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 1604-VLZ
PRO has a problem,
please do everything you can to confirm it before call-
ing for service. Doing so might save you from being
deprived of your mixer.
Of all Mackie products returned for service
(which is hardly any at all), roughly 50% are
coded “CND” — Could Not Duplicate, which usu-
ally means the problem lies somewhere other than
the mixer. These may sound obvious to you, but
here’s some things you can check:
TROUBLESHOOTING
Bad Channel
• Are the channels assigned to the correct mix
(
1-2
,
3-4
,
L-R
)?
• Is the
fader
up?
• Try unplugging any insert devices from the
INSERT
jacks.
• 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 you’re listening to the
C-R OUTS
or
PHONES
outputs, has a
SOURCE
selection
been made?
• If it’s one of the
MAIN OUTS
, try unplugging its
companion. For example, if it’s the
1
/
4
" LEFT
MAIN OUT
, unplug the RCA output. If the
problem goes away, it’s 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.
• Unplug everthing from the
MAIN INSERTS.
Noise
• Turn the channel faders and
AUX RETURN
knobs 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
switch on?
Check the fuse
.
REPAIR
Service for the U.S. version of the 1604-VLZ
PRO is only available from Mackie Designs, lo-
cated in sunny Woodinville, Washington. (Service
for mixers living outside the United States can
be obtained through local dealers or distribu-
tors.) If your mixer needs service, follow these
instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-258-6883, 8am to
5pm PST, to explain the problem and request
an R.A. number. Have your mixer’s serial
number ready. You must have a Return
Authorization number, or we may refuse
the delivery.
3. Set aside the power cord, owner’s manual,
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. Mackie is not respon-
sible for any damage that occurs due to
non-factory packaging.
5. Include a legible note stating your name,
shipping address (no P.O. boxes), daytime
phone number, R.A. number and a detailed
description of the problem, including how we
can duplicate it.
6. Write the R.A. number in BIG PRINT on
top of the box.
7. Ship the mixer to us. We suggest insurance
for all forms of cartage. Ship to this address:
Mackie Designs Inc.
SERVICE DEPARTMENT
16220 Wood-Red Rd. NE
Woodinville, WA 98072
8. We’ll try to fix the mixer within five
business days. Ask Tech Support for
current 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 in the same way in which
it was received. This paragraph does not
necessarily apply to non-warranty service.
