11. M&K 5.1 MULTICHANNEL & PRO-LOGIC SYSTEM SETUP GUIDE
The 5 Most Important Items In System Setup:
These instructions will help you make sure that you cover all steps in setting up a 5.1 multichannel or Pro-Logic
surround 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 Laserdisc or DVD called Video Essentials. If you don’t have one, you can
order it by calling 1-561-997-9073 or visit the web site at www.imagingscience.com.
Here are the instructions for speaker setup.
1. 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.
2. Locate the subwoofer.
A. The best place for the subwoofer is the corner with the best structural strength. If the
corners are roughly equal in construction, use the corner nearest the listening position.
If the listening position is in the front half of the room, place the subwoofer in a front
corner. If it is in the back of the room, place the subwoofer in a back corner.
If possible, avoid corners near doorways or openings.
B. If you are willing to experiment, another option is to place the subwoofer at the listening
position and walk around the room. Stand in and near each corner. The location where
you hear the tightest bass with the most impact is probably the best location in the room
for the subwoofer.
C. If multiple subwoofers are used, place them in the same location. Stacking is best, but
you can also put them side by side.
Another option for multiple subwoofers is to place them in different locations. This is appropriate when you have
limited choices in locating the subwoofer and none of the available locations work well. Try to place multiple
subwoofers at equal distances from the listening position to avoid phase cancellation.
2. Locate the surrounds. Determine the best position in the room. It will probably be the position used for THX
speaker, directly to the right and left of the main listening position on the side walls (so that a listener in the center seat
is directly between the speakers). If that doesn’t work or is not practical because of the room, try these locations: on
the ceiling; on the back wall, or in the back corners (using an M&K ST Corner bracket).
3. Install all wiring and interconnects.
4. Connect the subwoofer. Always use the processor/receiver’s subwoofer output.
5. Aim the front speakers (this is a must for THX front speakers). Use a laser level to align each speaker. Place
the level on the flat surface between the midranges and tweeters that is roughly in the center of the front baffle. The
red dot of the laser should be aligned to the center of the listener’s forehead at ear height. Make sure that the volunteer
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
