Description

The Boston Acoustics Micro System9000 II and Micro System9500 home theater speaker systems deliver powerful performances for movies and music from small speakers that virtually disappear in your listening room. The potent 120-wattPowerVent® subwoofer in the Micro System9000 II and theearth-shaking300-wattPowerVent® subwoofer in the Micro System9500 both produce exciting bass and powerful lowfrequency effects. In the Micro System9500, the four Micro90x II satellites and Micro90c II center channel all use the same drivers, creating a perfect sonic match across the front and rear stage. Each speaker houses aBoston-built,high-power,312" (89mm) midrange driver and our 1" (25mm) anodized aluminum dome tweeter with AMD to provide articulate dialog and lifelike imaging. These same drivers are also used in the front left/right satellites and center channel in the Micro System9000 II. All of the satellites in both systems includewall-mountbrackets for complete placement flexibility.

The key to both system’s powerful performance are the subwoofers’ high-currentamplifiers and DCD(Deep Channel Design) bass unit in a ported,down-firingenclosure. Built in Boston’sstate-of-the-artproduction facility, thislong-throwdriver 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 26Hz in the Micro System9500 and 29 Hz in the Micro System9000 II. Thedown-firingports further strengthen the deep bass response by coupling the subwoofer’s output to the floor, and are smoothly flared to eliminate audible turbulence. In addition, they both feature BassTrac®, a proprietary newBoston-designedcircuit that tracks the input signal to the subwoofer and prevents its amplifier from being driven into audible distortion. The benefit: The bass stays clean and strong at any listening level. For user convenience, the subwoofer features auto turn on/turn off circuitry that turns the subwoofer amplifier on automatically when a signal is sensed, and turns it off approximately 15 minutes after the last signal has been received. Easily accessible volume controls make both PowerVent subwoofers as convenient to use as they are exciting to listen to.

The Micro90x II and Micro80x II satellites and Micro90c II center channel are two-wayspeakers designed forwide-rangeresponse and a seamless blend with their respective subwoofer. They all feature MagnaGuard® magnetic shielding to prevent television picture distortion.

How to Wire Your Speakers

You need to wire your speakers correctly to obtain the best sound quality and Wiring should just take a few minutes, but it’s important to do it carefully, since (such as reversed connections) can result in a poor soundstage or poor

We recommend using 18-gaugeor larger speaker wire for runs up to 25 (8m), and thicker16-gaugeor larger for longer runs. Strip12" (12mm) lation off the ends of each speaker cable to expose the two conductors tightly twist the wire strands. Maintain consistency of the + (red) and – (black) nections 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.

Connecting Your MicroSystem

Speaker-LevelConnections

The simplest way to wire either system is via speaker connections. Wired in this way, the subwoofer 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 (see options 1, 2 and 3). 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 Micro90x II/80x II 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.

Dolby® Pro Logic® SystemsSpeaker-LevelConnection

The subwoofer and front satellites should be wired to connections for the front left and right speakers. Even though both MicroSystems have separate subwoofers, when you use speaker-levelconnections, their satellites and subwoofer look to your receiver like a pair of conventional large speakers. Set the center channel mode on your receiver to “NORMAL.” This will send all the bass to the subwoofer.

Dolby® Digital SystemsSpeaker-LevelConnection

The subwoofer and front satellites should be wired to connections for the front left and right speakers. Even though both MicroSystems have separate subwoofers, when you use speaker-levelconnections, their satellites and 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 MicroSystem’s subwoofer.

Testing the Connections

A simple listening test will tell you if your satellites are connected properly. Place the satellites face to face, with about an inch (25mm) between them. While listening to music, reverse the connections at one speaker only. You’ll hear a dramatic change in sound. The connection that yields the fuller and louder sound is the correct one.

After checking the satellites, you can perform this same test with the subwoofer by reversing the speaker wires at one of its two pairs of terminal connectors. If the bass output is reduced, then the original connections were correct.

Dolby Pro Logic and Dolby Digital

Line-LevelSystem Connection

Using the line-levelconnection to the subwoofer generally results in a cleaner system sound, since the receiver’s amplifier no longer has to reproduce the difficult low bass information that can push it into audible distortion (also known as clipping). If your receiver’s subwoofer out jack is labeled “Sub Out”, then connect it to the Micro subwoofer’s jack labeled “from sub out”. If your receiver’s subwoofer out jack is labeled “LFE Out”, then connect it to the Micro subwoofer’s jack labeled “from LFE out”.

Dolby Pro Logic Systems

Use an RCA cable (not included) to connect your receiver’s Sub out orLFE out jack to the appropriate Line in jack on the subwoofer, as shown below.

Set the center and surround channel modes to “NORMAL”. This will send all the bass to the subwoofer.
