Description

The Lynnﬁeld VR-MC center channel speaker delivers the wide-range response, high power-handling, high

efficiency and placement ﬂexibility required by the ﬁnest home theater systems. Its wide and even dispersion

ensures that the sound will remain consistent and uniform for listeners throughout the room, assuring that

everyone has the “best seat.”

Placement

Place the center channel speaker

above or below the television

monitor, as close as possible to

the center of the screen. It is not

necessary to angle the speaker to

face the listeners. The speaker

is magnetically shielded with

MagnaGuard®and will not affect

the television’s picture. Use the

four self-adhesive rubber feet

(provided) to protect the TV’s

ﬁnish and reduce vibration.

Connection

WARNING: To prevent an electrical shock hazard, always switch off the ampliﬁer or receiver when making

connections to the speaker.

We recommend 18-gauge, or thicker, wire for runs up to 25 feet (8m) and 16-gauge, or thicker, wire for longer

runs. Separate the ﬁrst few inches of the wire conductors. Strip off 1⁄2inch (12mm) of insulation from the ends

of each speaker wire to expose the two conductors and tightly twist the wire strands.

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.

Distance adjustment: Digital surround sound electronics permits the listener to adjust the relative timing of

the center channel sound. This adjustment affects the quality of the front image of the system. Refer to the

instructions provided with your surround sound electronics.

Bass management—speaker selection: Surround sound electronics provides adjustments or menus that

permit the listener to direct bass signals to speciﬁc channels for the best effect. Generally, with all surround

systems, the center channel mode should be set to SMALL. This setting will divert low bass to the front left

and right speakers (which typically have greater bass capability than the center speaker) and will result in

the greatest total system bass output. Also, if your system includes separate subwoofers, the SMALL setting

ensures that the subwoofers will receive the most bass under all conditions.

Bass management—crossover frequency selection: Some surround sound electronics provides a choice

of crossover frequencies (the frequency below which bass is diverted to the left, right, or subwoofer speak-

ers). If a choice is provided, 80Hz will give the best overall results.

Systems with Dolby®Pro Logic®only: On older systems with Dolby Pro Logic only, use the NORMAL or

SMALL settings for the center speaker. The PHANTOM setting, which presumes you do not have a center

channel speaker, should not be used.

Maintenance

Care and cleaning: The VR-MC features a solid wood top and real wood veneer back and sides. Therefore,

treat it as you would any ﬁne piece of furniture. Avoid harsh chemicals and ammonia-based cleaners and

only use furniture polish or oil soap when necessary.

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.

Connect the speaker to the center front terminals of your surround sound receiver

or ampliﬁer.

IMPORTANT: Be sure to connect +to +(red) and –to –(black).

Using the ﬁve-way binding posts: The binding posts permit easy connection to banana

plugs, spade lugs and bare wire. The metal surfaces are plated with 24K gold to prevent

corrosion. Insert the wire in the hole and tighten.

Listening Levels and Power-Handling

The power recommendation for the speaker assumes you will operate the ampliﬁer in a way that will

not produce distortion. Even rugged systems like the VR-MC can be damaged by an ampliﬁer if it is

producing 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.

Limited Warranty

For ﬁve years from the date of purchase, Boston Acoustics will repair for the original owner any defect in

materials or workmanship that occurs in normal use of the speaker, without charge for parts and labor.

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 representative.

This warranty is void if the serial number has been removed or defaced.

This warranty gives you speciﬁc legal rights, and you may also have other rights that vary from state to state.

If Service Seems Necessary

First, contact the dealer from whom you purchased the speakers. If that is not possible, write to:

Boston Acoustics, Inc. 300 Jubilee Drive Peabody, MA 01960 U.S.A.

We will promptly advise you of what action to take. If it is necessary to return your speaker to the factory,

please ship it prepaid. After it has been repaired, we will return it freight prepaid in the U.S.A. and Canada.
