MK Sound LCR-651 User Manual

If you mount the surrounds on the side wall behind the listening position, they can be aimed towards each other

or angled towards the back wall or the side wall surface directly behind them. By reflecting sound behind the
listening position, you may increase the sense of envelopment in the sound.

If you want or need to mount speakers on the back wall of the room, there are several options. You can aim

them so that they fire towards each other (so they fire along the back wall); you can aim them towards the front
wall of the room; or you can angle them so they fire toward the side walls. Symmetrical arrangements work best.

The speakers should be a minimum of a few feet away from the nearest listener. Ideally, the surround

speakers should not call attention to themselves as separate sources of sound.

If the surrounds must be located close to the listeners, aiming them at the room walls or even the ceiling can

help to reduce any directional effect. As described above, this can produce a desirable result even in rooms where
the surround speakers are an adequate distance from the listeners' heads.

If the surrounds cannot be placed on a wall, try placement on tables or the floor to the sides of the main

listening position, firing up towards the ceiling. This can work very well in environments that do not allow
permanent attachment of speakers to the walls.

Some listeners prefer to use multiple pairs of surround speakers. While this is not necessary, it can provide a

broader and deeper surround effect, with better coverage in very large rooms. When using multiple pairs of
surround speakers, a symmetrical installation pattern works best. For example, if you are using two pairs of
surround speakers, one pair could be mounted on the back wall of the room, mounted equidistant from the back
corners, with the other pair mounted on the side walls of the room, equidistant from the same back corners.

The surround channels can be installed in a wide variety of locations, but because they are usually mounted

on the walls of the room, they can be a challenge to successfully install. If you have further questions, please call
us at the M&K factory, and we will be happy to discuss them with you in detail.

Subwoofer location for Home Theatre systems is essentially the same as for music systems.

See our

Subwoofer operation manual for more details. Remember to leave 2 - 3 feet of clearance between any television
and subwoofer, unless the subwoofer is magnetically shielded.

The preferred connection for the subwoofer is a subwoofer output from the amplifier or controller. This insures

that a full bass signal is being fed to the subwoofer. If you do not have such a subwoofer output jack, connect the
subwoofer to the front Left and Right channel amplifier outputs (do not use the Center channel).

IF YOU ARE CONNECTING YOUR SUBWOOFER TO THE AMPLIFIER OUTPUTS: When the Subwoofer is

connected to the Left and Right amplifier outputs, and the controller is in Pro-Logic mode, the switch on the Pro-
Logic control unit labelled Center channel WIDE/NORMAL must be set to the NORMAL mode. If the switch is set
to the WIDE mode, the bass content of the Center channel will not be fed to the Subwoofer, and you will lose a
significant amount of bass.

In any system using a subwoofer separate from Main speakers, a phasing test must be performed to insure

good bass blending. This test insures optimum sound in the critical bass frequencies where your Subwoofer and
Main speakers overlap.

Play a familiar CD, DVD, LP, or tape with steady, consistent bass content through your system. Listen careful-

ly to the "mid-bass" region of 75 - 125 Hz. This is the part of the spectrum where electric or string basses and
drums predominate. Then reverse the phase of either the subwoofer or BOTH Main speakers.
