wall or corner. Moving it away from a wall or corner gives you less bass. Remember that the floor also
loads the Subwoofer, and that maximum bass is found with the woofer on the floor in a corner.
In some rooms, a corner location may excite resonance modes, resulting in a muddy or boomy
sound. In these rooms, a more central location along a wall, away from the corner, may give better
results. If you experiment, try to find a spot where no bass notes seem to overpower others and the
overall sound is powerful and clean. The goal is to achieve a smooth sound quality, with the entire bass
spectrum equally prominent. In most rooms, this is directly in the corner, not the center of the room.
Because the Subwoofer generates a great deal of energy, its output may vibrate objects close to
it. If you hear such vibration, you may need to damp the vibration of nearby objects.
One Subwoofer is sufficient in a stereo system because of the nature of human hearing. The ear-
brain hearing system is unable to locate the direction of bass sounds below approximately 100 - 150
Hz. The direction of low frequency sounds (drums, basses, etc.) is determined by the higher frequency
overtones and harmonics that are reproduced by the Satellite speakers.
All M&K Powered Subwoofers have exceptionally sharp (36 dB/octave) low-pass filters to remove
the midbass and midrange frequencies unwanted in a Subwoofer. This makes your M&K Subwoofer
truly non-directional.
Except for the MX-700, VX-100, and V-125, M&K Subwoofers are not magnetically shielded.
Leave 2 - 3 feet of clearance around any television set. Shielding avoids magnetization of the shadow
mask of the television's picture tube, which will distort the television's picture. If this ever happens to
your set, turn it off and on a few times to use the set's built-in degaussing circuitry. If the problem
persists, contact a TV technician and ask him or her to use an external degaussing coil.
No matter where you put the Subwoofer, you must allow room for ventilation of its heatsink and
backplate. The Subwoofer's power amplifier is mounted on the backplate, and it generates heat.
1.
Leave clearance around the Subwoofer's heatsink. Do not cover it with drapes.
2.
Do not place the Subwoofer near baseboard heaters or forced air heating outlets.
3.
Do not use the Subwoofer outdoors or in a humid environment.
Do not plug the Subwoofer into an AC outlet until all system wiring is complete.
4. SUBWOOFER HOOK-UP
There are two different ways to connect the Subwoofer to your system. One uses speaker wire,
and the other uses interconnect cable with RCA-type jacks. You must use RCA-type jacks to connect
the MX-700, MX-200, MX-125 Mk II, and VX-100.
If your receiver or processor has a SUBWOOFER OUTPUT RCA-type jack, use it. This is
the preferred connection for your M&K subwoofer. If your component does not, skip to "USING
SPEAKER WIRE CONNECTIONS" below).
You cannot use "TAPE OUT" jacks to connect your subwoofer, because these jacks have
a fixed output level that does not change when you adjust the system volume control.
