MCS 90 Introduction
Thank you for purchasing a Boston Acoustics Multi{hannel Speaker System.These speakers incorporate higtNuality cornponer]ts
that produce the famous Boston sound.The system is ideally suited for use as a 5.1 channel solution in a high-quality home
theater or music system. The system is complete with everything you need for the typical speaker system including speaker
wire, satellite speakers, a center channel speaker, and a subwoofer. Please check out Bostonacoustics.com/placement for
information or] placing your speakers.
The MCS 90 speaker system delivers exceptionally articulate on-screen dialog, music, effects, and room filling bass from a
small, sleek package. Compact driver placement and quality, system specific crossovers assure a wide uniform dispersion
for complete coverage of a listening room. All speakers also feature MagnaGuard '_magnetic shielding which ensures the
speaker's magnetic field does not interfere with the televisions picture.

Placement Options
The MCS 90 satellites and center char]nel are easily place(] on a tabletop or wall-mounted.The
speakers are configured for tabletop use when you first unpack the system. The foot installed ors
the rear of the speaker will keep it upright.
The MCS 90 satellites and center char]nel are designed to easily mount ors the wall using the keyhole
slot(s) ors the back of the speaker. When mounting the speakers to the wall use the supplied rubber
bumpers. You must remove the attached foot to wall-mount your speakers. Remove the thumbscrew
from the back of the foot. It is slotted for easy removal with a screwdriver or a coin.
The keyhole mour]ting option is similar to hanging a picture frame ors awall. Install a #8 screw (not
ir]duded) into the sheetrock, making sure to go into a stud, and hang the speaker or]to the screw head.
If a stud is not available, a sheetrock anchor should be used to support the weight of the speaker. It is
advisable to cor]nect the speaker wire prior to waiPmour]ting.

NOTE: Because there are so many different kinds of surfaces ors which the speakers could be mounted.There is no one
type of fastener that we could supply that would work in all the possible situations. So taking into account the surface the
speaker is being mounted ors, acq uire the appropriate type of fasteners. If you're not sure what type of fastener to use, take
the mounting bracket to a friendly hardware store, tell them about the wall you're mour]ting the speaker ors, and ask them
to recommend an appropriate fastener. Keep in mind the weight of the speaker.
Speaker Connections
After your speakers are properly place(], you are ready
to wire your system. First, turn offal[ system power.
Use the speaker wire included with the system to
make your cor]r]ectior]s. For longer distances, #16 or
#18 gauge wire available from your dealer should be
used. Please see the illustration for guidance con-
necting the wires to the MCS 90 satellites and center
char]nel.
For cor]nection to your receiver please refer to its
owner's mar]ual.

Important!
To ensure the best performance observe polarities when making speaker
cor]r]ections, as shown in the ilkJstration. Cor]nect each + terminal ors the back of
the amplifier or receiver to the respective + (red) terminal ors each speaker. Cor]nect
the (black) terminaB in the same way. Ifthe cor]r]ections are not made correctly it
carscause poor bass response and imaging. Also, to avoid short circuits that may
damage your equipment be careful not to let any of the bare wires touch each other.
+Red - Black
Subwoofer Connections
Turn offall power. Use the subwoofer cable included with your
system to cor]nect the subwoofer to your receivers Subwoofer or
LFE Output. Cor]nect the other end to the"Line In"on the back of
the Subwoofer.

Subwoofer Controls
Power On
Plug the subwoofer's AC cord into a wall outlet. We do not recommend using use the
outlets or] the back of the receiver. The subwoofer features auto on/stand by. An LED
indicator next to the volume control indicates what mode the subwoofer is in.
RED = STANDBY (No signal detected, Amp Off)
GREEN = ON (Signal detected, Amp Or])
/
/'
',, /
//
/
LED indicator
Thesubwoofer will automatically enter the Standby mode after severalminutes when no signal is detected from your system.
Thesubwoofer will then power ONinstantly when a signal is detected.
Volume Control
Begin by adjusting the Subwoofer Volume Control to the 11 otlock position. Further adjust the Subwoofer Volume Control
until you hear a match in volume between the main speakers and subwoofer. Ideally, bass response should not overpower
the room but rather be adjusted so there is a natural blend across the entire musical range.
Operation
When using the MCS gO in a Dolby _ Digital or DTS'_'home theater system, make sure all speakers are set to"Srnall". When
using the system in a Dolby Pro Logic _°home theater system, make sure the receiver's center channel mode is set to'Normal."
Some Dolby Digital equipped receivers/processors offer different setup options for each source or surround mode (e.g., CD-
stereo, videotape, Dolby Digital, Pro LogicS°).In each case, follow your equipment's instructions to ensure that the subwoofer
output is turned or] and that the speakers are set to"Small"in each mode.
If your receiver hasadjustable crossover settings, we recommend the subwoofer crossover be set at 150Hz.
Refer to the owner's manual for your AV receiver for any additional recommendations or] system operation.
Maintenance and Service
The satellite and subwoofer enclosures may be cleaned using a soft cloth to remove fingerprints or to wipe off dust. All wiring
cor]r]ections should be inspected and cleaned or remade at least once a year.
Ira problem does occur, make sure that all cor]r]ections are properly made, secure and clear]. Ira problem occurs in one loud-
speaker, rewire that speaker in a different location within the system. Should the problem persist in this speaker the problem
is within the speaker. If the speaker sounds fine in the new position it is a strong indication of a more in depth issue with the
electronics in the system. In the event that your MCS gO ever needs service, contact your local Boston Acoustics dealer or visit
www.Bostona.com for a list of dealers in your area.
If your subwoofer does not play,check that all the connectors or] the cables are making proper contact and that the AC plug
isconnected to a "live"receptacle.
