MK Sound CENTER-850 - Manual (Page 5)

WIRING
The Positive ( + ) lead from your amplifier or receiver should be connected to the RED ( + ) "INPUT"
terminal, and the Negative ( — ) lead from your amplifier or receiver should be connected to the BLACK ( — )
"INPUT" terminal. See Figure 1 below.
4. THE M&K HIGH-FREQUENCY PRISM SYSTEM (850 and 650 series only)
Your LCR-850, Center-850, and LCR-650 speakers utilize M&K's exclusive High-Frequency Prism System to
optimize imaging and coverage of sound throughout the listening area. This system is designed to take into
account the effect of the curved mesh metal grilles on your speakers. Therefore, your speakers are designed for
the best sound when the grilles are in place. We recommend that you leave the grilles on the speakers for
all listening.
You will note that the tweeter in your LCR-850, Center-850, and LCR-650 speakers is mounted at a slight angle
(4.7 degrees). This mounting is an integral part of the High-Frequency Prism System.
When the speakers are mounted properly, the tweeter will be angled away from the listening position. That
means that the left and right channel speakers should be placed with the tweeter angled towards the nearest side
wall. The left channel speaker's tweeter should point towards the left wall, and the right channel speaker's
tweeter should point towards the right wall.
The center channel speaker should be placed with the tweeter pointing up when it is sitting above the
listening position (such as when it sits on top of a projection television set). The center channel speaker should
be placed with the tweeter pointing down when it placed underneath the television screen.
When the speaker is mounted as described above, its stereo imaging and coverage of sound are optimized
for a very wide listening window that extends from the on-axis position towards the center of the room. If the
speaker is mounted with the tweeter pointed in the other direction, its sound quality will be adversely affected.
The 851 and 651 series speakers have a fabric grille and therefore do not use the High-Frequency
Prism system.
5. CENTER-850 CENTER CHANNEL HIGH-FREQUENCY PRISM
The Center-850 is designed to match the LCR-850 so all instructions apply to both speaker versions. The
Center-850 is designed to be oriented horizontally and located above or below your television screen. For more
discussion of center channel speaker placement, see CENTER CHANNEL on page 7.
