10. Power Sources: The product should be connected to

a power supply only of the type described in the operating instructions or as marked on the product.

11. Grounding or Polarization: This product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will ﬁt into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to ﬁt, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.

12. Power Cord Protection: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention to cords and plugs, convenience receptacles, and the point where they exit from the product.

13. Cleaning: The product should only be cleaned as recommended by the manufacturer.

A. The power supply cord or the plug has been damaged;

B. Objects have fallen or liquid has been spilled into the product;

C. The product has been exposed to rain;

D. The product does not appear to operate normally or exhibits a marked change in performance; or

E. The product has been dropped or the enclosure damaged.

17. Servicing: The user should not attempt to service the product beyond what is described in the operating instructions. For all other servicing, consult your dealer or contact Boston Acoustics.

Description

The Boston Acoustics System8000 home theater system delivers powerful performance for movies and music from small

speakers that virtually disappear in your listening room. A potent 65-watt PowerVent

subwoofer produces exciting bass

and special effects. The two Micro80x left/right satellites and Micro80c center channel speaker use the same drivers,

creating a perfect sonic match across the front stage. Each speaker houses a Boston-built, high-power, 3

⁄2" (89mm)

midrange driver and our

⁄4" (19mm) wide-dispersion dome tweeter to provide articulate dialog and lifelike imaging.

Completing the system are two compact Micro80e rear effects speakers, for realistic, three-dimensional cinema sound.

The front satellites and rear effects speakers include wall-mount brackets for complete placement ﬂexibility.

The key to System8000’s powerful performance is the subwoofer’s high-current ampliﬁer and 7" (180mm) DCD

™

(Deep

Channel Design) bass unit in a two-chamber bandpass enclosure. Built in Boston’s state-of-the-art production facility, this

long-throw driver was optimized using Finite Element Analysis computer modeling, giving it tremendous excursion for

exceptionally powerful bass. The subwoofer ampliﬁer features active equalization, extending the system’s bass response

down to 45Hz. The down-ﬁring ports further strengthen the deep bass response by coupling the subwoofer’s output to the

ﬂoor, and are smoothly ﬂared to eliminate audible turbulence.

The Micro80x satellites and Micro80c center channel are two-way speakers for wide-range response and a seamless blend

with the subwoofer. They feature MagnaGuard

magnetic shielding to prevent television picture distortion.

For user convenience, the subwoofer features auto turn on/turn off circuitry that turns the subwoofer ampliﬁer on automat-

ically when a signal is sensed, and turns it off 15 minutes after the last signal has been received.

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

⁄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.

Micro80x Satellites and Micro80c Center Channel

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.

Micro80pv Subwoofer and Micro80e Effects Speaker

Push down the buttons and insert the wire where shown. Be sure to connect + to + (red) and – to – (black).

Insert the wire in the hole and tighten.

To connect two wires to one terminal, ﬁrst twist them together. Then insert the wire in the hole and tighten.

Speaker level input

Connecting the System8000

Speaker-Level Connections

The simplest way to wire the Micro80p is via speaker connections. Wired in this way, the subwoofer (Micro80pv) does not present any additional load to your ampliﬁer. There are three ways to wire the subwoofer to your speaker connections; each way produces the same result. You may want to use long wires to the subwoofer at ﬁrst, so you may experiment with placement.

As a general rule, it is best to keep the total length of wire between the ampliﬁer and Micro80x satellites as short as possible. The subwoofer, on the other hand, is not sensitive to wire length.

Be sure to connect + to + (positive) and – to – (negative) by using the markings on the wire.

WARNING: To reduce the risk of electrical shock, always switch off the system and the ampliﬁer and/or receiver when making connections to the system and speakers.

The subwoofer and front satellites should be wired to connections for the front left and right speakers. Even though the System8000 has a separate subwoofer, when you use speaker-level connections, the two Micro80x satellites and Micro80pv subwoofer look to your receiver like a pair of conventional large speakers. On your receiver’s setup menu, set the front left/right speaker mode to “LARGE.” Choose “SUBWOOFER-NO.” Set the center channel and surround speaker modes to “SMALL.” This sends all the bass to the front left and right channels, where it will be reproduced by the System8000’s subwoofer.
