Description

The Lynnfield VR965 and VR975 deliver accurate, wide-range performance that conveys all the power and impact of the most demanding program material. These floorstanding speakers combine integrated powered subwoofers with Boston-built midranges and tweeters into sleek cabinets that blend gracefully in any listening room.

Both models feature high-current subwoofer amplifiers driving our long-excursion, Deep

Channel Design (DCD TM ) bass units for deep, authoritative low frequencies. In addition, they both feature BassTrac TM , a proprietary new Boston-designed circuit that tracks the input signal to the subwoofer and prevents its amplifier from being driven into audible distortion. Unlike conventional limiters, BassTrac preserves the waveform’s shape, maintaining the fidelity of the signal. The benefit: The bass stays clean and strong at any listening level. For user convenience, an auto on/off function turns the subwoofer amplifier on when a bass signal is sensed, and turns it off approximately fifteen minutes after the last signal is received.

Our midrange units feature copolymer cones, butyl rubber surrounds, and a computeroptimized magnet structure for smooth, accurate midrange reproduction. A 1" (25mm) anodized aluminum Lynnfield VR tweeter, with our exclusive Amplitude Modification Device

(AMD), produces extended, sparkling high frequencies.

The cabinets are constructed of Medium Density Fiberboard (MDF), chosen for its outstanding acoustic characteristics, and have extensive internal bracing. The result is superb structural integrity that eliminates the spurious resonances and vibration that degrade the sound of ordinary speakers.

MagnaGuard ® magnetic shielding ensures the speaker’s magnetic field does not interfere with the television’s picture, allowing placement next to a TV in a home theater system.

How to Connect Your Speakers

Correctly wiring your speakers is important for achieving the best sound quality. Wiring should take just a few minutes, but it’s important to do it carefully, since incorrect wiring (such as reversed connections) can result in a poor soundstage and poor bass.

We recommend 18-gauge wire or thicker for runs up to 25 feet (8 meters) and 16-gauge wire or thicker for longer runs. Separate the first few inches of the wire conductors. Strip off 1/2-inch

(12mm) of insulation from the ends of each speaker wire to expose the two conductors and tightly twist the wire strands.

WARNING: To prevent electrical shock hazard, always switch off your amplifier or receiver when making connections to the speaker. After wiring your speakers, plug them into an AC wall outlet.

We recommend you do not plug them into a switched outlet on the back of your receiver or into a power strip that will be turned on and off.

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, spade lugs, and bare wire.

Insert the wire in the hole and tighten.

Connecting the VR965 or VR975 to Stereo or Dolby

®

®

Systems

For stereo or Dolby Pro Logic systems, the easiest method is to use speaker wire connections as shown. You may also use the “sub out” connection from your receiver to the input on the speaker marked “sub in,” but you will need RCA cables and a Y-connector to split the “sub out” signal between the two speakers (see illustration on page 8).

965/75 MANUAL 11/99rev1 1/14/00 12:04 PM Page 8

Connecting the VR965 or VR975 to Digital Theater Systems

Digital 5.1 home theater electronics dedicate one channel (the “.1” of 5.1) to reproduce the special low-frequency information (such as explosions and thunder) contained in digital-encoded soundtracks.

Use RCA cables and a Y-connector (not included) as shown to connect your digital receiver’s subwoofer output to the speakers. Select “subwoofer-yes” from your receiver’s set-up menu.

Hooked up this way, the receiver’s amplifier is relieved of having to reproduce the difficult low bass signals that can drive the receiver into audible distortion. In addition, the LFE signal will be cleaner, since it is taken directly from the pre-amp/processor section of the receiver and doesn’t pass through an additional layer of circuitry (the receiver’s amplifier) before going to the speaker.

Generally, you will get the best results by selecting “small” for the front left and right speakers from your receiver’s set-up menu. However, we suggest you try both settings (“small” and

“large”) to see which sounds best with your particular receiver.

If you do not wish to run RCA cables to your speakers, you may configure your electronics to send the LFE signal along with the left and right channel signal using the speaker wire connection (see illustration on page 7). Select “subwoofer-no” from your receiver’s set-up menu. This sends the LFE signal to the main left and right speakers. Consult your system electronics owner’s manual for more details.

Checking the Speaker Connections

It is important that your speakers are hooked up with similar polarity, or “in phase.” A simple listening test will tell you if your speakers are connected properly. While listening to music with your amplifier set to MONO, reverse the speaker wire connections at one speaker only. You’ll hear a dramatic change in sound. The connection that yields the fuller bass and louder sound is correct.

Bass/Sub Control

This control adjusts the amount of deep bass produced by the speakers. Use this control to increase or decrease the bass level to compensate for the effects of room placement or personal taste.

NOTE: The most musically accurate response will be obtained when the control is in approximately the 9:00 o’clock position.

965/75 MANUAL 11/99rev1 1/14/00 12:04 PM Page 10

How to Place Your Speakers

As a starting point, place the speakers 6 to 12 feet (2-4m) apart, so they form a triangle with your favorite listening position. The speakers should be at least 2 feet (0.6m) from the corners of the room. Placement near the walls or corner will reinforce the bass. Placement too far away from the walls or corner may result in a “thin,” bass-shy balance. Putting the speakers too close to a corner can produce an unnatural bass reinforcement that detracts from their balanced, uncolored sound. If a speaker must be placed near a corner, move it away from the wall directly behind it to preserve its natural tonal balance. Use the bass/sub control to obtain the best balance in your room.

Generally, the best results will be obtained when the woofers face out, away from each other.

However, the nondirectional nature of bass propagation means that either orientation will produce satisfactory results. If you do place the woofers facing in, make sure they have at least six inches of “breathing room” from the furniture or TV stand for proper bass reproduction.
