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 CR1604-VLZ has a problem,
please do everything you can to confirm it before
calling 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
usually 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 disap-
pears, 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 CR1604-VLZ
is only available 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.
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. If you don’t have a box, please
let Tech Support know that you need a new
one when you call for the R.A. number.
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 recommend United
Parcel Service (UPS). We suggest insurance
for all forms of cartage. Ship to this address:

ship it back to you UPS RED (Next Day

apply to non-warranty service.
