How to Wire Your Speakers
You need to wire your speakers correctly to obtain the best sound quality and the proper
image. Wiring should just take a few minutes, but it’s important to do it carefully, since incorrect
wiring (such as reversed connections) can result in a poor soundstage or poor bass.
We recommend using 18-gauge or larger speaker wire for runs up to 25 feet (8m), and thicker
16-gauge or larger for longer runs. Strip
1
⁄2" (12mm) of insulation off the ends of each speaker
cable to expose the two conductors and tightly twist the wire strands. Maintain consistency of
the + (red) and – (black) connections by using the markings on the wire.
IMPORTANT: Typically, one side of the wire is
smooth. Connect this side to the – (black) connection. The other side has a rib or stripe.
Connect this to the + (red) connection.
Using the five-way binding posts: The binding
posts permit easy connection to banana plugs,
pins, spade lugs, and bare wire. The metal
surfaces are plated with 24K gold to prevent
corrosion.
Insert the wire in the hole and tighten.
Connections
WARNING: To prevent electrical shock, always switch off the amplifier or receiver when making
connections to the speaker.
Micro90c Center Channel
Connections
Connect the speaker’s terminals to the
center channel terminals on the amplifier or receiver. Maintain consistency of
the + (red) and – (black) connections
by using the markings on the wire.
Micro90x and 80x Satellite
Connections
Connect the satellites to the amplifier
or receiver terminals designated for
surround or rear channel effects.
Usually, these will be labeled as “Left
Rear” and “Right Rear.” Maintain consistency of the + (red) and – (black)
connections by using the markings on
the wire.
Placement
Micro90c Center Channel Placement
Place the Micro90c as close to the TV
monitor as possible, with its front panel
flush with the front of the television.
Self-adhesive rubber feet are included
with the Micro90c to protect the TV’s
finish and prevent vibration.
Micro90x and 80x Satellite Placement
For the most realistic surround
effects, place the surround speakers
so the sound is diffused around the
listening area. Avoid pointing them
directly at the listeners.
IMPORTANT: Be sure to hook + to +, – to –.

Wall-Mounting the Micro Satellites
The Micro satellites may be wall-mounted using the included keyhole bracket.
Install a #8 or #10 mounting screw on the wall (not sup-
plied–consult a knowledgeable installer regarding the
proper hardware to use on your wall).
Attach the bracket to the back of the speaker with the
machine screw and acorn nut as shown.
If you are running wires behind the wall, make a
3
⁄8"
(9.5mm) wire hole, 1
3
⁄4" (44mm) below the mounting screw
for the wire.
The speaker may be angled for optimum coverage of the
listening area.
An optional pedestal shelf stand/wall-mount bracket (Model MRB) is available for the Micro80x
that provides greater positioning flexibility. For more information, contact your dealer or
Boston Acoustics directly.
Setting Up Your Home Theater System
Volume Levels: To obtain the best home theater effect, match the sound levels of each speaker. Home theater systems include a test signal that simplifies this level matching. Refer to the
instructions provided with your surround sound electronics.
Center Channel Mode: Generally, with all surround systems, including Dolby®ProLogic®and
Dolby
®
Digital, the center channel mode should be set to “NORMAL” or “SMALL.” This setting
diverts low bass to the front left and right channels, and will result in the greatest total system
bass output. The “NORMAL” or “SMALL” center speaker setting ensures the subwoofer
receives the most bass information under all conditions. The “Phantom” setting, which presumes
you do not have a center channel speaker, should not be used.
Surround Channel Mode: If your electronics have a surround channel mode, it should also be
set to “NORMAL” or “SMALL.” This setting will divert any low bass in the surround channels to
the subwoofer.
