Repair
Service for the CFX MKII Series mixers is
available at a factory-authorized service center.
Service for Mackie mixers living outside the
United States can be obtained through local
dealers or distributors.
If your mixer needs service, follow these in-
structions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-898-3211, 8am
to 5pm PST, to explain the problem in
detail. If it appears that the mixer needs
repair, you will be given a Service Request
Number. Have your mixer’s serial number
ready. You must have an Service Request
Number before you can obtain service at a
factory-authorized service center.
3. Keep this owner’s manual and the detach-
able linecord. We don’t need them to repair
the mixer.
4. Pack the mixer in its original package,
including endcaps and box. This is VERY
IMPORTANT. When you call for the Service
Request 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.
5. Include a legible note stating your name,
shipping address (no P.O. boxes), daytime
phone number, Service Request Number,
and a detailed description of the problem,
including how we can duplicate it.
6. Write the Service Request Number in BIG
PRINT on top of the box. Product shipped
without the Service Request Number will
be refused.
7. Tech Support will tell you where to ship the
mixer for repair. We suggest insurance for
all forms of cartage.
8. We’ll try to fix the mixer within five
business days. Once it is repaired, we’ll ship
it back the same way in which it was
received. This paragraph does not neces-
sarily apply to non-warranty service.
Note: You must have a sales receipt from
an Authorized Mackie Dealer to qualify for
a warranty repair.
