Mackie 24.8Bus Owner's Manual - Page 56

SERVICE SERVICE PLEASE! SAVE THE SHIPPING BOX! Yes, we know it's only slightly smaller than a doublewide mobile home, but you will need the entire carton and internal foam if your console ever needs service at some time in the future. If your kids make the box into a fort and cut holes in it - or if you stuff it in the dumpster of the fast-food place next door to your studio, we may have to sell and ship you another packing box later on. Don't end up buying an empty box! Intermittent signal problems. Faulty plugs and cables are often the culprits. A TRS plug can sit in a socket for months doing its job and then suddenly decide (based on the phase of the moon and barometric pressure) to short or stop conducting. If you're having trouble with an individual channel, send or return, for gosh sakes swap cables before sending the board in for service. Check switch positions. Multi-bus consoles are pretty complicated. Switches like MIC/LINE, FLIP and EQ SPLIT can give the impression that something isn't working right, if you're not expecting them to be engaged. Finally, it doesn't hurt to call our Technical Support Department at 800/258-6883 (8AM4:30PM Pacific time) to see if they have any ideas as to what might be wrong. Note: For best results have unit in front of you (or close by). Mackie mixing systems are notoriously bulletproof and reliable. But, hey...stuff happens. Any electronic product with as many parts as an 8•Bus console can occasionally have a minor casualty somewhere inside. And even if we could build our products to never break, there are those acts of nature that tend to visit consoles on occasion: spilled coffee, toppling monitors, etc. This section covers how to get your Mackie 8•Bus console healthy again. How to get Mackie service Service and repairs of Mackie 8•Bus products are to be performed only : A. at our factory OR B. at an Authorized Mackie 8•Bus Warranty Service Center Unauthorized service, repairs or modification will void your warranty. To obtain factory service: Troubleshooting It benefits everyone if you do a bit of basic troubleshooting first, to determine whether or not your board is really malfunctioning. First, it saves you downtime and embarassment if, for example, you discover that the only thing wrong is an unplugged power supply. Second, it will save money. If you ship your console to Mackie or an Authorized Service Center and they can't duplicate the problem, you may get slapped with a service charge (plus shipping costs). We could write a whole manual on troubleshooting, but our main point is that there are a few obvious things you can easily look for: Power connections. This sounds insultingly simple, but if the whole board is completely dead, it's time to make sure that the power cable is connected, that the console power supply is turned on, plugged in, etc. You may also need to unplug the AC cord from the power supply to gain access to the little "drawer" (in the AC receptacle) in order to check the AC fuse. 1. Call Mackie Technical Support at 800/258-6883, 8AM to 4:30PM Monday through Friday (Pacific Time) to get a Return Authorization (RA). Please have your serial numbers ready.[Products returned without an RA number will be refused.] 2. Pack the 8•Bus Series Console and Power Supply in their original shipping cartons. If you do not have the carton, request one when you get your RA number, and we'll send a shipping carton out promptly. There may be a charge for this gigantic bale of white cardboard, however - we put those huge "SAVE THE BOX" warnings in this manual for a reason. Make sure that you encase the console in its plastic wrapper and insert all the foam blocks to properly protect the console. 3. In some cases, the problem might be the console OR the power supply. Just to be sure, send both. 54
