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 its 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 12" (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.

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.

Wall-Mounting the Micro Satellites  
The Micro satellites may be wall-mounted using the included keyhole bracket.  
1
Install a #8 or #10 mounting screw on the wall (not sup-  
1
plied–consult a knowledgeable installer regarding the  
proper hardware to use on your wall).  
2
Attach the bracket to the back of the speaker with the  
machine screw and acorn nut as shown.  
3
If you are running wires behind the wall, make a 38"

2
(9.5mm) wire hole, 134" (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 II) is available for the  
Micro90x II and Micro80x II 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.

Listening Levels and Power-Handling  
The power recommendation for the system assumes that you will operate the amplifier in a way  
that will not produce distortion. Even our rugged speakers can be damaged by a modest  
amplifier if it produces distortion. If you hear a harsh, gritty noise, turn down the volume.  
Prolonged or repeated operation of your speaker with a distorted signal from the amplifier can  
cause damage that is not covered by the warranty.

Your responsibilities are to use the system according to the instructions supplied, to provide  
safe and secure transportation to an authorized Boston Acoustics service representative and to  
present proof of purchase in the form of your sales slip when requesting service.  
Excluded from this warranty is damage that results from abuse, misuse, accidents, shipping or  
repairs or modifications by anyone other than an authorized Boston Acoustics service
