POWERED SUBWOOFER
IF YOU NEED TO REPLACE THE EXTERNAL FUSE:
Disconnect supply cord before changing fuse. Replace fuse only with same type.
Remove the fuse cap and inspect the fuse. Look carefully at the fuse. If the wire filament inside the glass is bro-
ken, replace the fuse ONLY with one of the identical size and value. Using a fuse of a larger value will void your war-
ranty AND MAY CREATE A FIRE HAZARD. Plug the subwoofer back in. If it does not work, unplug it immediately, and
contact your dealer or M&K for service.

13. M&K 5.1 MULTICHANNEL & PRO-LOGIC SYSTEM SETUP GUIDE
The 5 Most Important Items In System Setup:
1. Find the best location for the subwoofer for maximum output and flattest response
(usually the corner closest to the listening position)
2. Aim the front speakers (and the surrounds, if possible) vertically for the flattest
response and best imaging
3. Set all speakers to the Small setting for proper High-Pass and Low-Pass Filter
operation to get the lowest distortion and maximum dynamic range
4. Calibrate all speakers and the subwoofer to the identical level for proper imaging
and balance
5. Make sure all speakers are in phase for proper imaging and impact
These instructions will help you make sure that you cover all steps in setting up a 5.1 multichannel or Pro-Logic sur-
round sound system. In addition to following this list, make certain that you study and understand the owner's manual
for each and every component used in the system, especially the processor/receiver's manual. Have fun and good luck!
A useful tool for system setup is the DVD called Video Essentials. If you don't have one, you can order it by visiting
www.videoessentials.com.
Here are the instructions for speaker setup.
A. Locate the front speakers. The left, right, and center speakers should be equidistant from the main
listening position. Try to set up the speakers so that they are reasonably symmetrical to room surfaces.
A tape measure may be very helpful.
