For the most balanced performance use an MC630HD on all channels of the surround-sound system. They are also excellent to use as
rear or surround speakers in a system using MC650HD front speakers. If you prefer smaller or in-wall surround and rear speakers, any of the
Cambridge SoundWorks Newton Series speakers may be substituted with good results. The Left, Center, and Right speakers should all be the
same for the most accurate sound stage.
The MC630HD is intended for use in systems that contain one or more subwoofers, and is not designed to reproduce the deep bass range.
Use a receiver or AV processor that incorporates a high-pass crossover whenever possible. If you must use the MC630HD with a receiver
or amplier that does not contain a high-pass lter, make sure the “o” or “wall” side of the bass contour switch adjacent to the input terminals
is pressed. Setting this switch to “|” or “Stand” when driven with a full-range signal can result in damage to the speaker if the signal contains
strong bass.
System Conguration
The proper placement of speakers affects how well the AV surround system recreates the sound eld intended by the recording engineer.
Current recording practice typically 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 specic 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 reected sound from the wall degrades the
sound coming directly from the speaker.

Wiring The Speakers
If you wish to conceal the wire within the walls, it is easiest to run
the wires to their nal positions prior to mounting the speakers.
The spring loaded terminals of the MC630HD 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.
•
•
Preparing The Wires
Determine how long the speaker cable should be for each
speaker. Cut the speaker cable into the appropriate lengths.
Route the wire to each speaker location.
Strip 1/2 inch of insulation from the two individual conductors
in the speaker cable. Twist the exposed strands of bare wire
together.
Determine which conductor you will use to connect the positive
terminals of the amplier 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.

Strip 1/2 inch
To Attach The Wires
Press the speaker’s red terminal to expose the hole in its shaft.
Insert the stripped end of one cable’s positive conductor into the
speaker’s red (+) terminal.
Release the terminal to secure the connection. Make sure no
stray strands of wire are present.
Repeat the procedure for the cable’s other conductor and the
speaker’s black (–) terminal.
Connect the opposite end of the speaker cable to the speaker
outputs of your receiver. Remember to observe channel and
polarity (Left Positive, Left Negative, Right Positive, Right
Negative).
Repeat the process for each speaker.

Speaker Mounting
Use a keyhole slot to hang the speaker from a screwhead.
The MC630HD may be wall mounted or placed horizontally on a
table-top as a center-channel using the included hardware. Matching
oor and table-top stands are available separately from Cambridge
SoundWorks.
Hanging The Speaker On The Wall
The MC630HD may be mounted either vertically or horizontally
using the supplied wall anchors.
Using the dimension diagram as a guide, mark the position of
two locations for mounting screws and anchors. The anchors
will not be needed if you can locate the speakers directly over a
wall stud. If concealing the wiring in the wall, you should arrange
the speakers so that the wire exits the wall directly behind
the center of the speaker. Drill a ¼” diameter hole and install
wall anchors in each location. Refer to the instructions below
for proper use of the Toggler brand anchors included with this
speaker.
Insert the #10 screws into each anchor and screw them partially
in leaving approximately 3/8” exposed. Test t the speaker on
the screws and adjust both screws so that the speaker hangs
rmly on the wall without rattling.
Attach the wire to the speaker terminals. Slide the speaker on
the screws from the top.

Placing Horizontally On a Tabletop Or Shelf
Attach the rear support into the channel on the rear of the
speaker using the included ¼-20 machine screw. Tighten the
set-screw nger-tight to stabilize the support.
Attach two rubber hook-shaped stick-on feet symmetrically
along the bottom edge of the speaker approximately 10” apart.
If you are mounting the speaker on an uneven surface you may
need to attach the feet closer to the center. Adapt the actual
position to your needs.
Remove the logo by pulling it straight out. Turn it 90 degrees so
that the text reads correctly. Press it back in place.

Setting Bass Contour
The switch located near the connection terminals optimizes the low
frequency response of the speaker for wall or stand mounting.
When the speaker is mounted on a speaker stand, away from
the wall press the end of the switch marked with “|”.
When the speaker is mounted on the wall or table, press the
end of the switch marked with “o”. The upper bass range will
be slightly attenuated to compensate for the increase in bass
caused by wall reection.
•
•
The above recommendations should yield the most accurate
response in each example, but they are optional. If you prefer the
sound with settings opposite the above recommendations, feel free to
use your settings instead.
Note: Always place the switch in the “o” position if you are
using amplier or receiver that does not have a high-pass lter
on the speaker outputs. Receivers and ampliers that do not
have separate subwoofer outputs are in this category.
The MC630HD can be safely used with any receiver rated above 30 watts per channel. There is little advantage in using more power than
100 watts per speaker, but receivers above this power rating can be used so long as the receiver is not operated at distorted levels.
Operating a receiver (of any power rating) beyond its maximum undistorted output level creates distortion – added high frequency sound not
part of the musical program. Distortion dramatically increases the internal operating temperature of a speaker and will eventually cause the
speaker’s failure due to burned or melted internal parts. While Cambridge SoundWorks includes the most heat-tolerant parts commensurate
with good acoustic design, the speaker’s Limited Warranty against defects in materials or workmanship does not apply to parts that fail from
long-term operation at very high temperatures.
Warning About Excessive Amplier Distortion
The speaker enclosures can be cleaned with a soft, damp cloth or mild cleaner.
Brush or vacuum the grille panels with a soft brush attachment to your vacuum cleaner.
If you suspect there is a problem with your Newton HD loudspeaker, contact the retailer where it was purchased or a Cambridge
SoundWorks Audio/Video Consultant, who will help you track down the problem. If together you agree there is something wrong with your
Newton HD loudspeaker, return it to the retailer that sold it to you. Mail-order and Internet retailers will generally require a Return Authorization
number. Products purchased from a Cambridge SoundWorks store, you may call us for a factory Return Authorization. Do not return the
Newton HD loudspeaker or any parts without rst obtaining a Return Authorization.
