ongratulations on your purchase of the RBH MC Series Theater
loudspeaker system! Your speakers are the result of many years of
research and development dedicated to producing high quality products for
home audio and audio/video systems.
This manual contains features, setup recommendations and specications for
RBH MC Series loudspeaker systems. We recommend that you thoroughly
read through the material contained in this manual before connecting your
loudspeakers. This will insure that you have a good understanding of how to
setup your speakers for optimum performance.
INTRODUCTION
BREAK IN PERIOD
lan on giving your speakers 10-15 hours of playing time to adequately
break in. As the speakers break in, the driver suspension will loosen
up. The result will be an increase in low frequency response, improved denition,
clarity and detail.

FEATURES
t the heart of our MC Series loudspeaker system is a proprietary aluminum
cone bass/midrange driver (speaker). The unique aluminum cone material
combines stiffness, low mass, and self damping properties in a manner that allows
virtually uncolored presentation of program material. A powerful magnet, extended
voice coil and bumped back plate give the bass/midrange driver high excursion
capability, which ensures accurate dynamic reproduction. The drivers are shielded
by using a steel cup and an additional magnet to cancel any stray magnetic eld
that many cause interference with video equipment such as tube televisions.
For high frequencies, a proprietary aluminum dome tweeter was developed.
This tweeter uses Ferro Fluid® liquid cooling allowing the tweeter to handle
greater power while retaining detail and accuracy.
Steep acoustic slope crossovers are used to integrate drivers. A polyswitch,
or current limiting device, is used in the crossover to prevent damage to
the tweeter if overdriven.
Resonance Damping Alloy Bafe technology will dampen
cabinet vibrations and minimize tweeter diffraction, all while giving a visually
pleasing look to the speaker.
Cabinets are constructed of MDF. Front bafes are extra thick to prevent
any excess acoustic radiation and have a narrow prole to minimize cabinet
diffraction. Large oversized binding posts ensure a good electrical contact.
Sophisticated computer modeling and measurement techniques are used
extensively in the RBH loudspeaker design process.

SETUP SUGGESTIONS
hen attaching speaker wire to the terminals, we suggest removing the
black and red plastic protective inserts. To do this, loosen the binder from
the post by twisting counter-clockwise until the binder is removed completely
from the post. Remove the plastic inserts by pulling straight out, then replace
the binder to the post and twist clockwise. A hole is provided in the post to allow
for speaker wire to slide into, then the binder is tightened until the wire is secure.
Remember to strip the insulation from the wire prior to inserting into the post.
In order to extract the best possible sound from your speaker system, it is
important to determine where the speakers will sound best in your listening
room. Room reections from the oor, ceiling and side walls inuence the
balance, imaging and overall sonic quality at the listening position. We
suggest that you experiment with speaker placement to determine which
location offers the best overall sound. The diagram on page 5 should be
used as a general guide when setting up a home theater system and follows
the descriptions in the following paragraphs. Some speakers shown in the
diagram will not always be applicable to your individual system.
The model MC-6CT comes with stabilizing feet. To install, place each foot
so that the center hole of the foot is over each pilot hole on the bottom of
the cabinet. Use the supplied screws to attach, noticing that the pilot hole is
drilled on an angle. This is done so that the foot will be pulled in tight against
the speaker cabinet. Install either the supplied spike or rubber mount as
necessary into the threaded insert.

SETUP SUGGESTIONS CONTINUED
s a starting point, we recommend placing your left and right MAIN
speakers at least 15 inches from the back wall and 7 feet apart from
each other. The distance from the listening position to each speaker
should be close to the distance that separates the two main speakers.
Angling the speakers inward towards the listening position may give a
more spacious and realistic sound stage.
The CENTER channel speaker should be placed in the center between both
left and right main speakers. Often this positioning dictates placing the speaker
either directly above or below a television monitor. Since all MC Series prod-
ucts are video shielded, the center speaker may be placed close to a television
without cause for concern. If using an MC-414C, the speaker may be in a
horizontal (lying down) or vertical position.
SURROUND* speakers may be placed either above, behind or to the sides of the
listening position. The listening position should be at the center of both surround
speakers. For best performance you may want to experiment with angling the
surround speakers either towards or away from the listening position.
*There are several different surround formats available. Dolby Pro-Logic, Pro-Logic II, Dolby Digital and
DTS generally have a 5 speaker plus subwoofer requirement. Dolby Digital EX and DTS ES add a center
rear speaker. Please consult your audio/video professional to determine which system is best for you and
how many speakers you will require.

CARE & CLEANING
o maintain speaker appearance, we recommend an occasional application of
furniture grade polish to the wood surface of the cabinet. To clean dust
from the grille cloth, use a vacuum with a brush attachment.
