APPENDIX A: Service Info

Warranty Service

Details concerning Warranty Service are spelled out in the Warranty Card included with your mixer. If it’s missing, please let us or your dealer know.

If you think your DFX Mixer has a problem, 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.

These may sound obvious to you, but there’s some things you can check. Read on.

Troubleshooting

Bad Channel

•Is the channel Fader turned up?

•Is the MUTE switch on?

•On mono channels, try unplugging any INSERT devices.

•Try the same source signal in another channel, set up exactly like the suspect channel.

Bad Output

•Are the MAIN MIX faders turned up?

•If it’s one of the MAIN OUTs , try unplug- ging all the others. For example, if it’s a TRS MAIN OUT, unplug the associated XLR outputs. 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 left speaker is still dead, it’s not the mixer.

Noise

•Turn the channel Faders , AUX RETURN and AUX SEND controls down, one by one. If the sound disappears, it’s either that channel or whatever is plugged into it, so unplug whatever that is.

Power

•Our favorite question: Is the POWER switch on? Are all the lights out in your building?

•If the POWER LED is blinking, switch the mixer off for a few seconds, and disconnect all connections except the linecord. Switch it back on, and if the LED continues to blink, the mixer may need repair.

Repair

Service for DFX mixers sold in the USA is

available at our factory, located in sunny Wood- inville, 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 1-800-258-6883, 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. This is very important. When you call for the RA number, please let Tech Support know if you need new packaging. Do not use packing “peanuts” or any small packing pieces which could get inside the mixer. Always wrap it in a plastic bag. 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:

Mackie Designs
SERVICE DEPARTMENT
16140 Wood-Red Rd. NE, Ste 5
Woodinville, WA 98072

8.We’ll try to fix the mixer within three to five business days. Ask Tech Support for the latest turn-around times when you call for your RA number. The mixer MUST be packaged in its original packing box, and must have the RA number on the box. Once it’s repaired, we’ll ship it back the same way in which it was received. This paragraph does not necessarily apply to non-warranty repair.
