APPENDIX A: 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 mixing board 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. 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 lay somewhere other than the mixer. These may sound obvious to you, but here's some things you can check: TROUBLESHOOTING Bad Channel • Is the mute switch in the correct position? • Is the gain turned up? • Try unplugging any insert devices. • Try the same source signal in another channel, set up exactly like the suspect channel. Bad Output • Is the associated level knob (if any) turned up? • If it's an aux send or sub problem, is the FLIP switch set correctly? • 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 switches sides, it's not the mixer. Noise • Mute the channels and aux returns one by one. If the sound disappears, 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? • Are all of the status LEDs on? • Check the fuses. Please refer to the power supply documentation to change the fuse. REPAIR Service for the U.S. versions of our mixers is available only from one of our authorized domestic service stations or at the factory, lo- cated 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 RA number. Have your mixer's serial number ready. You must have a Return Authorization number, before you can obtain service at the factory or an authorzed service center. 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. 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 recommend United Parcel Service (UPS). We suggest insurance for all forms of cartage. Ship to this address: Mackie Designs SERVICE DEPARTMENT 16220 Wood-Red Rd. NE Woodinville, WA 98072 8. We'll try to fix the mixer within three 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 BLUE (Second Day Air). However, if you rush your mixer to us by Air Shipment, we'll treat it in kind by letting it jump to the head of the line, and we'll also ship it back to you UPS RED (Next Day Air). This paragraph does not necessarily apply to non-warranty service. 62
