The proper placement of speakers affects how well the AV
surround system recreates the soundfield intended by the
ecording engineer. Current recording practice typically
r
assumes a speaker array with a center channel speaker
directly in front of the central viewing position. Left and right
speakers are placed so they each form a 30 degree angle
from the centerline. Left and right surround speakers should
be 110 degrees from the centerline. Left and right rear
speakers in a 7.1 system should be at 140 degrees. If a single rear speaker is used in a 6.1 system, it should be centered on the rear wall. Front speakers should be as close to
the height of the TV monitor as practical. Surround and rear
speakers should be slightly higher. Recreate this speaker
pattern as closely as your room and furnishings allow.
Don’t be too concerned if your situation and listening environment dictate the speakers’ position. Most rooms do not
allow ideal placement. Place your speakers as close to
these guidelines as practical. The speakers will still provide
convincing, lifelike sound.
Your surround processor has a variety of adjustments to
optimize the sound based on the speakers’ capabilities and
placement. These adjustments vary by processor, so refer
to your processor’s manual for instructions specific to your
equipment. Set your main, center, and surround settings to
“SMALL”, with subwoofer “ON”. If your processor allows you
to adjust the crossover frequency, set it as close to 100Hz
as possible.
• Avoid placing front left and right speakers very close to a
side wall (within 12-14 inches). The reflected sound from the
wall degrades the sound coming directly from the speaker.

WIRING THE SPEAKERS
Strip 1/2 inch
f you wish to conceal the wire within the walls, it is easiest
I
to run the wires to their final positions prior to mounting the
speakers.
The spring loaded terminals of the MC650HD accept bare
wire between AWG #12 and AWG #18 (lower numbers are
thicker). It is not necessary to “tin” the wire or use connectors to terminate the wire.
• Use at least AWG #18 speaker cable for short runs
(under 15 feet). Use AWG #16 or heavier speaker cable
for longer runs.
• Building codes typically require plenum rated wire for
installation within walls. Be sure to use wire that complies
with any applicable local building codes. Plenum rated
cable typically has an outer jacket with individually
insulated conductors inside the outer jacket. Some brands
of plenum rated cable may be too thick to fit the space
between the wall mount bracket and the speaker. To use
heavier plenum rated speaker cable with the wall mount
brackets, remove the outer jacket and any filler cord back
to the point where the wire exits the wall.
Preparing the wires:
1. Determine how long the speaker cable should be for
each speaker. Cut the speaker cable into the
appropriate lengths.
2. Route the wire to each speaker location.
3. Strip 1/2 inch of insulation from the two individual
conductors in the speaker cable. Twist the exposed
strands of bare wire together.
4. Determine which conductor you will use to connect the
positive terminals of the amplifier and speaker together.
Printing or a ridge on the insulation usually distinguishes
one of the two conductors. Sometimes the metal of the
conductors has two different colors, or the insulation
color of each conductor may be different.
