Mackie 1402-VLZ Pro Owner's Manual - Page 29

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 1402-VLZ PRO 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/ALT 3-4 switch in the correct position? • Is the fader turned up? • Try unplugging any INSERT devices (Channels 1-6 only). • Try the same source signal in another channel, set up exactly like the suspect channel. Bad Output • Is the associated level control (if any) turned up? • If it's one of the Main outputs, try unplugging all the others. For example, if it's the 1⁄4" Left Main out, unplug the RCA and XLR Left outputs. If the problem goes away its 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 problem stays on the left it's not the mixer. Noise • Turn the channel fader and AUX RETURN knobs down, 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? • Check the fuse . REPAIR Service for the U.S. version of the 1402-VLZ PRO is available only from Mackie Designs, located 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, or we may refuse the delivery. 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 a new box. 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 16220 Wood-Red Rd. NE 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 three-day shipping. However, if you rush your mixer to us by next-day air, we'll treat it in kind by shipping it back in the same way in which it was received. This paragraph does not necessarily apply to non-warranty service. 29
