Repair

Service for the CFX Series mixers is available only at our factory, located 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 in- structions:

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 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.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.

5.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.

6.Write the RA 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:

16140 Wood-Red Rd. NE, Ste. 5
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 UPS OR- ANGE (three-day air). However, if you rush your mixer to us by Next Day Air, we’ll treat it in kind by shipping it back to you the same way in which it was received. This paragraph does not necessarily apply to non-warranty service.
