Placement Options
+ –
+ –
The MCS 90 satellites and center channel are easily placed on a tabletop or wall-mounted. The
speakers are congured for tabletop use when you rst unpack the system. The foot installed on
the rear of the speaker will keep it upright.
The MCS 90 satellites and center channel are designed to easily mount on the wall using the keyhole
slot(s) on 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 mounting option is similar to hanging a picture frame on a wall. Install a #8 screw (not
included) into the sheetrock, making sure to go into a stud, and hang the speaker onto 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 connect the speaker wire prior to wall-mounting.
NOTE: Because there are so many dierent kinds of surfaces on 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 on, acquire 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 mounting the speaker on, and ask them
to recommend an appropriate fastener. Keep in mind the weight of the speaker.
Speaker Connections
After your speakers are properly placed, you are ready
to wire your system. First, turn o all system power.
Use the speaker wire included with the system to
make your connections. For longer distances, #16 or
#18 gauge wire available from your dealer should be
used. Please see the illustration for guidance connecting the wires to the MCS 90 satellites and center
channel.
For connection to your receiver please refer to its
owner’s manual.
Important!
To ensure the best performance observe polarities when making speaker
connections, as shown in the illustration. Connect each + terminal on the back of
the amplier or receiver to the respective + (red) terminal on each speaker. Connect
the – (black) terminals in the same way. If the connections are not made correctly it
can cause 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.
Subwoofer Connections
Turn o all power. Use the subwoofer cable included with your
system to connect the subwoofer to your receivers Subwoofer or
LFE Output. Connect the other end to the “Line In” on the back of
the Subwoofer.

Subwoofer Controls
MCS 90
Power On
Plug the subwoofer’s AC cord into a wall outlet. We do not recommend using use the
outlets on the back of the receiver. The subwoofer features auto on/standby. An LED
indicator next to the volume control indicates what mode the subwoofer is in.
RED = STANDBY (No signal detected, Amp O )
GREEN = ON (Signal detected, Amp On)
The subwoofer will automatically enter the Standby mode after several minutes when no signal is detected from your system.
The subwoofer will then power ON instantly when a signal is detected.
LED indicator
Volume Control
Begin by adjusting the Subwoofer Volume Control to the 11 o’clock 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 90 in a Dolby® Digital or DTS™ home theater system, make sure all speakers are set to “Small”. 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 oer dierent setup options for each source or surround mode (e.g., CDstereo, videotape, Dolby Digital, Pro Logic®). In each case, follow your equipment’s instructions to ensure that the subwoofer
output is turned on and that the speakers are set to “Small” in each mode.
If your receiver has adjustable 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 on system operation.
Maintenance and Service
The satellite and subwoofer enclosures may be cleaned using a soft cloth to remove ngerprints or to wipe o dust. All wiring
connections should be inspected and cleaned or remade at least once a year.
If a problem does occur, make sure that all connections are properly made, secure and clean. If a problem occurs in one loudspeaker, rewire that speaker in a dierent location within the system. Should the problem persist in this speaker the problem
is within the speaker. If the speaker sounds ne 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 90 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 on the cables are making proper contact and that the AC plug
is connected to a “live” receptacle.
