Mackie Mix 50 Owners Manual - Page 15

APPENDIX A: SERVICE INFORMATION Warranty Service Details concerning Warranty Service are spelled out in the Warranty section on page 23. If you think your TAPCO 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 here are some things you can check. Read on. Troubleshooting Bad Channel • Is the channel GAIN turned up? • Is the channel LEVEL turned up? • Try the same source signal in another channel, set up exactly like the suspect channel. Bad Output • IS the MAIN MIX control turned up? • 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 LEVEL controls down, one by one. If the noise 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? Ha! Fooled you. There is no POWER switch. • Is the external power supply securely plugged into the POWER connector on the back of the Mix Series mixer? • Is the external power supply plugged into an AC power strip? Make sure the power to the power strip is turned on. • Are all the lights out in your building? Repair Service for TAPCO mixers is available at a factoryauthorized service center. Service for TAPCO 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 1-877-827-2669, 7 am to 5 pm PST, to explain the problem and obtain a Service Request Number. Have your mixer's serial number ready. You must have a Service Request Number before you can obtain factory-authorized. 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 Service Request Number, please let Tech Support know if you need new packaging. You can order new packaging through our parts department. TAPCO 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 Service Request Number in BIG PRINT on top of the box. Units sent to us without the Service Request Number will be refused. 7. Tech Support will tell you where to ship the amplifier for repair. We suggest insurance for all forms of cartage. 8. We'll try to fix the mixer within five business days. Ask Tech Support for the latest turn-around times when you call for your Service Request Number. The mixer must be packaged in its original packing box, and must have the Service Request 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 nonwarranty repair. Note: You must have a sales receipt from an Authorized TAPCO Dealer to qualify for a warranty repair. Lonely?
