SERVICE INFORMATION

Warranty Service

Repair

Details concerning warranty service are spelled out on page 11 of this manual.

If you think your subwoofer has a problem, please do everything you can to confirm it before calling for service, including reading through the following Troubleshooting section. Doing so might save you from being deprived of your Mackie subwoofer.

Of all Mackie products returned for service (which is hardly any at all), many are coded “CND” — Could Not Duplicate— which usually means the problem lay somewhere else in the system. The following troubleshooting tips may sound obvious, but here are some things you can check:

Troubleshooting

Service for Mackie products is available at a factory- authorized service center. Service for Mackie products outside the United States can be obtained through local dealers or distributors.

If your S218s needs service, please follow these instructions:

1.Review the preceding troubleshooting suggestions. Please.

2.Call Tech Support at 1-800-898-3211, 7 am to 5 pm PST, to explain the problem in detail. They will ask you all sorts of impertinent questions in the hope of sorting out the problem. If it appears that the S218s needs repair, you will be given a Service Request Number. Have your subwoofer’s serial number ready. You must have a Service Request Number be- fore you can obtain service at a factory-authorized service center.

No sound

•Are the level controls on the mixer or amplifier turned all the way down? Follow the procedures in the “Quick-Start” section on page 4 to verify that all the volume controls in the system are properly adjusted.

•Is the signal source working (and making union scale)? Make sure the connecting cables are in good repair and securely connected at both ends.

•Make sure the mixer does not have a Mute on or a Processor loop engaged. If you find something like this, make sure the volume/gain is turned down before disengaging the offending switch.

Poor bass performance

•Check the polarity of the connections between the mixer and all the loudspeakers and subwoofers. You may have your positive and negative connec- tions reversed at one end of one cable, causing one loudspeaker to be out-of-phase.

Poor sound

•Is it loud and distorted? Make sure that you’re not overdriving a stage in the signal chain. Verify that all level controls are set properly.

•Is the input connector plugged completely into the jack? Make sure all connections are secure. It’s a good idea to periodically clean all electrical con- nections with a non-lubricating electrical contact cleaner.

3.Keep this user’s manual. We don’t need it to repair the subwoofer.

4.Pack the subwoofer in its original packaging, including protective wrap, 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. 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, Service Request 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. Product shipped with- out the Service Request Number will be refused.

7.Tech Support will tell you where to ship the sub- woofer for repair. We suggest insurance for all forms of cartage.

8.We’ll try to fix the subwoofer within five business days. Once it is repaired, we’ll ship it back the same way in which it was received. This paragraph does not necessarily apply to non-warranty service.

Note: You must have a sales receipt from an Autho- rized Mackie Dealer to qualify for a warranty repair.
