1. INTRODUCTION
Congratulations! Your new M&K speaker system will give you years of unmatched enjoyment and excitement
while listening to your favorite musical and audio/video sources.
We encourage you to read this owner’s manual, as there is a great deal of information provided here to help you
achieve the best possible performance.
If you have any questions about your speaker system, please contact your M&K dealer or call the M&K factory
directly at (310) 204-2854, from 8:30 AM to 5:00 PM Pacific Time, Monday through Friday. We will be happy to help
you with any question, no matter how simple or complex it may be. Additional information may also be obtained on
our web site: www.mksound.com or you may send us an e-mail at support@mksound.com.
This manual gives you basic hook-up instructions first, followed by more detailed technical, installation, and
service information.
2. PLACEMENT OF YOUR SPEAKERS
Your M&K speakers can be installed in a wide variety of locations. Their compact size gives you great flexibility
in installation. They can be placed on stands, shelves, or bookcases, or more permanently mounted using brackets,
through direct attachment to a wall, or with a ceiling suspension system.
If you want to mount your speakers permanently using wood screws, their cabinet thickness is 3/4". Do not use
longer screws, as you may damage the internally mounted crossover.
You can place the left and right speakers virtually anywhere in the room, but certain locations are better than
others. In general, locate them away from obstructions that would interfere with the direct path from the speakers to
your ears (such as walls, furniture, lighting, plants, etc.). Center channel speakers should be located close to the
television screen (see Home Theater Usage on page 6). Your speakers will sound better when they are around ear
height, or when angled towards your listening location. They sound better when they are not sitting on the floor.
Your speakers can be used with OmniMount® Systems brackets, without the use of wood screws, because their
cabinets have integral threaded hardware in patterns for OmniMount brackets. These brackets offer tremendous
flexibility for installation in a wide variety of environments. For more information, see Section 13 (page 10), or contact
OmniMount at (602) 829-8000.
For more detailed information on placement of your speakers, see Section 6 (page 5).
SPECIAL NOTE - THE Bookshelf-75, LCR-55MkII, Center-55MkII and LCR-45 ARE TV SHIELDED
Your speakers are magnetically shielded. This means that you can locate them close to a television set or even
directly on top of the set.
In some rare instances, a small amount of residual magnetism at a specific angle to your TV set may cause a
slight geometric or color distortion of the picture on your television set. If you do get this distortion, try moving the
speaker slightly until the distortion is reduced or disappears. Then turn the set off and wait 10 minutes before turning
it back on to trigger the set's degaussing circuitry. If you cannot solve any magnetic problems, contact the M&K factory.
3. SPEAKER HOOK-UP
Please follow these instructions carefully, to avoid any possible damage to the speakers or your amplifier, and
to get the best possible sound.
The sound quality of your speakers can be affected by the type of speaker wire that you use to connect them.
While it is possible to use speaker wire as thin as 22 gauge to hook your speakers up, we recommend using the largest
diameter wire that you can. This means a minimum of 18 gauge wire. Over 10 feet, you should use 16 gauge, and
for more than 30 feet, we recommend using 14 gauge or heavier. The smaller the number, the thicker the wire.
There are a very wide variety of premium speaker cables available from a number of specialist manufacturers.
We do not endorse any specific brand of premium cable, but we do recommend using as high quality a cable as fits
your budget. Using better quality cables will improve the sound of your Satellites.
Your M&K Speakers are not designed for bi-wiring. If you wish to bi-amplify your speakers in combination with
an M&K Powered Subwoofer, see Section 10 (page 9) for more details.
HOOKUP
For each speaker, connect the Positive (+) lead from your amplifier or receiver to the RED (+) INPUT terminal
