2. INTRODUCTION
Congratulations! You have just made perhaps the most exciting and dramatic addition that you could make to your
audio or multichannel audio/video system. The new dimension of deep and powerful bass provided by your M&K
VX-series powered subwoofer will thrill and excite you.
We encourage you to read this owner's manual, as there is a great deal of information provided here to help you get
the best possible performance. This manual gives you basic hook-up instructions first, followed by more detailed
technical, installation, and service information.
If you have any questions about your subwoofer, please contact your M&K dealer, or call us directly at
(818) 701-7010, from 8:30 AM to 5:00 PM Pacific Time. We will be more than happy to help you with any question.
You can also access our web site at: www.mksound.com or send us an email to [email protected].
3. VOLTAGE SELECTOR AND POWER CORD
Adjacent to the AC power cord receptacle on the back of the subwoofer you will find a "Voltage" switch. This switch
is pre-set at the factory for the proper local voltage, so there is no need to change the switch setting. For U.S. and
Canada operation, the proper voltage setting is 115V.
WARNING: This voltage selector must be set to the correct local voltage with the proper fuse installed.
Attempting to operate the subwoofer with the switch set to the incorrect position may damage the subwoofer
and there is a risk of fire. Any such damage is not covered by warranty.
If you have any questions regarding this switch, please contact your dealer or the M&K factory.
DETACHABLE POWER CORD
The VX-860 and VX-850 are provided with a detachable power cord. This cord must be attached to the subwoofer
BEFORE the cord is plugged into the AC wall socket.
4. WHERE TO LOCATE YOUR SUBWOOFER
M&K subwoofers perform well in most room locations. Unless your ear is a foot or two away from the subwoofer,
you will hear the deep bass coming exclusively from your satellite (or main) speakers. There is no need to place your
subwoofer in between the satellite speakers.
For the best performance, we recommend that your subwoofer be placed against a wall, preferably in a corner.
The ideal place for the subwoofer is the corner with the best structural strength. If the corners of your room 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 the listening position is in the back of the room, it may be best to place
the subwoofer in a back corner.
Feel free to experiment with the orientation of the subwoofer cabinet. Sometimes the best sound results from
aiming the subwoofer's driver directly into the wall (1" to 2" from the wall itself).
If possible, avoid corners near doorways or openings.
Another option to find the best location for the subwoofer 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.
If you are using multiple subwoofers, place them in the same location. Stacking is best, but you can also put them
side by side. See Section 9, page 10.
Alternately, you can put multiple subwoofers 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.
