IDEO

The next time you’re in a movie theater, shut your eyes and just listen to the movie. Listen carefully to the voices, music and sound effects with the same critical ear you would use to judge a stereo system. Without the big impressive picture commanding most of your attention and manipulating your emotions, it is easy to hear how substandard the sound truly is. Then try several different seats throughout the theater; you will find that they all have about the same poor sound.

In a theater, it is more important that every viewer be able to understand the dialog, hear the music and experience the sound effects than it is for the dialog, music and sound effects to sound real. Theater systems are engineered so that the kid in the front row right under the screen and the guy way back in the rear corner hear adequate sound even if it is detrimental to the sound in the central part of the theater. The sonic performance for the best seats is compromised to improve the performance for the worst seats. Engineering for this extreme level of consistency, guarantees consistent mediocrity. Luckily, it is not a mediocrity we have to live with in our home systems.

During the development of the VCC-5 we had the enlightening opportunity to use and evaluate numerous theater, home theater and audio/video systems with a wide assortment of equipment and configurations. We found that certain audio/video systems had better clarity, greater intelligibility and a faithfulness to the original sonic truth that other systems could not match. Based upon these superior systems, we developed some recommendations on building an audio/video system that would allow you, your family and your friends to experience videos, laser discs, DVDs, CDs, records and even broadcast television with maximum sonic realism.

START WITH A GOOD MUSIC SYSTEM

An accurate, detailed two speaker music system is the perfect basis for a high-fidelity audio/video system.

Speakers and electronics that sound real on music will also sound real on voices and other film sounds. Films contain many sounds of real life that we hear everyday so we instinctively use those familiar sounds to evaluate the visual realism. If your system cannot realistically reproduce familiar sounds as well as familiar sights, you will never be fully drawn into the emotional experience of a film.

Whether you build your audio/video system from scratch or as an extension of an existing music system, the performance of the core components—the front left and right speakers, the preamplifier and the main front amplifier—will define the ultimate capabilities of the entire system. The core components are where an investment in better speakers or a superior preamplifier or power amplifier will significantly improve the performance of your system on both film and music.

A DD S UBWOOFERS

Once you have the core components, the next step in building an audio/video system is the addition of subwoofers.

While subwoofers are optional in a music system, they are an integral and required part of an audio/video system. Movie makers take considerable artistic license with the low frequencies to create incredible sound effects that could never occur in the real world. Even with full-range main speakers and a powerful main amplifier, the high-intensity low frequency sound effects in modern movies can only be fully experienced with subwoofers and can actually damage a system without subwoofers.

To insure proper blending with subwoofers, filter theory dictates that the main speakers must have predictable response at least an octave below the crossover point. For an

80Hz subwoofer crossover point, the main speakers must have predictable response to 40Hz or lower. This is why it is impossible to successfully mate subwoofers with minispeakers—the small speakers simply cannot reach the required full octave below any reasonable subwoofer crossover point. Mated with full-range speakers however, powered subwoofers reduce the demands on the main amplifier as well as the speakers so that the system's treble and midrange are improved along with the bass.

There are significant advantages to using two subwoofers in an audio/video system rather than a single unit. Summing the channels into a single subwoofer alters or cancels all the low frequency information containing phase differences between the channels. Stereo subwoofers reproduce all of the bass information complete with the phase differences. Multichannel processors sound better with the LFE (Low Frequency Effects) information redirected to the front left and right channels where stereo subwoofers are located. Stereo subwoofers are also more linear than a single unit since they introduce the bass into the room at two different places and lend themselves to natural placement in the corners where the low frequency room gain is desirable on spectacular film sound effects.

Whether you use one or two, the Vandersteen 2Wq powered subwoofer is an extraordinary performer in a highfidelity home theater system where it has the power, cone area and frequency extension for you to fully experience the most intense low-frequency film sound effects. The high motor-to-cone-area ratio of the 2Wq’s three 8 inch drivers reduces distortion and provides a more seamless transition to the main speakers than is possible with a larger driver. The

2Wq features adjustable Q so the bass can be optimized for a music or home theater system and tailored to match your room and personal taste. In a system where the LFE output features and configuration options are desirable, a V2W can be added.

F ROM S TEREO T O S URROUND A ND B ACK A GAIN

Now that the core system and subwoofers are in place, it is time to provide surround sound capabilities to the system. In a system built around a preamplifier and power amplifier,

Vandersteen Audio VCC-5 Operation Manual 2

this functional metamorphosis will require an external surround sound processor that is compatible with the core electronics, a pair of speakers for the surround channels and an amplifier to drive them. An A/V receiver based system will only require the addition of the surround speakers as the processor and surround amplifier are already built into the receiver.

In a system with separates, a surround sound processor inputs to the surround amplifier or surround speakers to limit the low bass.

To drive the surround speakers in a separates based system, choose an amplifier matched to the power requirements of the speakers that has similar sonic characteristics to the amplifier driving the main speakers. This can be either a stereo amplifier or two channels of a multi-channel A/V amplifier. that can be inserted into the tape loop of the preamplifier will allow you to engage any of the surround sound modes for movie viewing while still being able to switch the processor and other surround related equipment completely out of the system for listening to stereo CDs or records. This will give you maximum flexibility since the system is not compromised to favor one listening mode over another.

There are several performance attributes to consider when selecting surround speakers for a high-fidelity home theater system. You are not forced into the compromises of a theater so you can use uncompromising speakers with precise imaging that enhances the spaciousness of your system and insures satisfying and stable surround effects. While small bookshelf surround speakers often have these desirable imaging characteristics, they do not have the bass extension or power handling capability of larger speakers.

This is usually not a problem with conventional matrixed narrow baffles usually sound decent through the critical

A center channel speaker and an amplifier to drive it are the final components you need to complete the audio portion of your audio/video system. The center channel speaker will help localize dialog and other film sounds at the screen for viewers seated outside of the central listening area. During a movie, much of the sound you hear will be coming from the center speaker so it must be carefully chosen to properly integrate with the main speakers.

While adding a good, well-matched center channel speaker will improve the system’s performance for listeners seated to the sides, a poor center channel speaker will completely ruin the sound of the system for everyone. No center speaker is always preferable to a poor or mismatched center speaker.

C ONNECTIONS

The VCC-5’s barrier strip provides superior gas-tight connections that do not deteriorate with time. The center speaker should be connected with cable similar to what you are using to connect the main speakers.

Connect the VCC-5 as follows:

1. Crimp and solder spade lugs to the speaker ends of the cable for your center channel as shown in illustration #

1. With a pair of pliers, slightly bend the spade lugs’ blades so that the body of the spade lug will be held away from the input plate once the wires are connected as shown in illustration # 2.

2. Connect the center channel cable to the VCC-5 as shown in illustration # 3. The input screws should be snug, but should not be over tightened.

P HASE

Like all Vandersteen speakers, the VCC-5 is phasecorrect with its tweeter, mid-range and woofers connected in positive polarity through transient-perfect, first-order crossover networks. When it is used with Vandersteen or other phase-correct main speakers, the VCC-5 should be connected in positive polarity.

(Amp + to speaker +, amp - to speaker -.)

(The only rare exception would be when the center channel amplifier or the main amplifier inverts phase. If you believe that one of your amplifiers inverts phase, contact the amplifier’s manufacturer for verification. Most modern amplifiers do not invert phase.)

When the VCC-5 is used with mixed-phase main speakers, it should be tried both in-phase and out-of-phase to determine which polarity provides better integration into the system. If you have difficulty determining the best polarity for the VCC-5 with mixed-phase main speakers, your dealer should be able to help you.

(Please do not call the factory with phase questions about a mixed-phase system. There is nothing regarding the proper connections for the VCC-5 in this type of system that can be determined over the phone. Someone from your dealer will need to come to your home and evaluate the possible configurations with their trained ears.

P LACEMENT

The triaxial design of the VCC-5 enables it to be placed at any height relative to the main speakers and the listeners without affecting its performance. If possible, the center speaker should be located farther away from the listeners than the main speakers. This additional distance will slightly delay the center channel sound which often improves the spatial characteristics of the system.

D IRECT V IEW O R R EAR P ROJECTION TV S

In most systems with a direct view or rear projection

TV, the VCC-5 should be centered on the top front edge of the TV. The center speaker will probably be somewhat higher than the main speakers which will raise the overall image up slightly and localize the dialog and other center channel information on the upper part of the screen. When your TV is built into a cabinet or wall unit, the VCC-5 should be built in directly above the center of the TV. If your TV is tall or mounted high enough that the center speaker is two feet or more above the listener’s heads, some rubber or plastic feet can be put below the rear of the speaker to tilt the front of it slightly downward toward the listeners. In situations where direct view TVs are mounted very high, the center speaker may perform better placed under the TV.

F RONT P ROJECTION TV S

The large screen of most front projection TVs along with their lack of a suitable surface to hold the center speaker can present some special challenges to positioning the VCC-5. With a conventional nonperforated screen at a normal height, the center speaker is usually mounted on a stand just below the screen. With smaller screens or screens that are lower than normal, the center speaker may perform better mounted above the screen. If the center speaker is mounted two feet or more above the listener’s heads, it should be angled slightly downward as described in the earlier section. With a perforated screen, the VCC-5 should be placed behind the screen, as close to the center as possible.

We do not recommend using double center speakers in any installation. Two VCC-5’s will interfere with each other and cause a loss of definition and linearity. If for some reason you have to run two center speakers, they should be mounted above and below the screen, not to the sides, and they both should be the same distance from the listeners.

M AGNETIC S HIELDING C ONSIDERATIONS

While it is impossible to totally eliminate the magnetic field of a high-quality, large-magnet driver such as the ones in the VCC-5, we use two stages of shielding to reduce it to a level where it will not present a problem in most applications. We have used the VCC-5 on many different TVs and even on the most sensitive, we have always been able to eliminate any interference with the following methods.

The VCC-5 has a stronger magnetic field to the front and rear than it does to the top, bottom or sides. On a sensitive direct view TV, hold the speaker high above the top of the TV as you approach it and then lower the speaker directly down onto the top of the TV.

When the position of the VCC-5 on the TV has been set, you should degauss the TV either by pushing its degauss button or turning the TV off and on several times.

(Modern TVs automatically degauss after a set number of power cycles.) If the center speaker is moved, the TV should be degaussed again.

With a direct view TV, when the final positioning for the VCC-5 has been set, the TV should be degaussed. If your TV does not have a degauss bottom, turn the TV on and off several times. Modern sets will automatically degauss within a few power cycles. If the center speaker is moved, the TV should be degaussed again.

The VCC-5 contains protection circuitry that tracks voice coil temperatures and reduces the current to one or more of the driver elements if excessive temperatures are detected.

When this happens, the sound of the speaker will change. If this occurs, immediately reduce the volume level to allow the speaker components to cool down. Please remember that no protection circuitry is 100% effective and that repeated activation could cause the circuits themselves to fail.

Vandersteen Audio 5 VCC-5 Operation Manual

B ALANCING L EVELS

Surround processors have a built-in pink noise generator that is used with a Sound Pressure Level meter to balance the volume levels of the various speakers in the audio/video system. (An SPL meter is a required tool for properly setting-up an audio/video system. Radio Shack sells an inexpensive SPL meter with more than adequate accuracy.) Do not try to balance the levels by ear. The frequency range difference between the center and main speakers will affect your perception of the pink noise levels and result in improper balancing.

Some processors can be programmed for use with a big or small center speaker. With the VCC-5, the processor should be set for a big center speaker provided that this setting does not remove the bass from the front left and right channels. For very high play back levels the processor should be bandpass limited to 60-80Hz 6dB per octave. If your processor does not have this option contact your dealer for a X-2 Outboard High Pass Filter at the input of the center channel amplifier.

To achieve the correct balance, the VCC-5’s Proximity Compensation must be turned off when the levels are set using the noise generator. Balancing the levels with the Proximity Compensation turned on will not cause any damage, but the level of the center channel will probably be set too high.

Once the speaker levels have been balanced, they should not need to be altered unless the system components are changed, the speakers are repositioned or the listening area is moved.

To avoid the possibility of a false reading, always turn off the VCC-5’s Proximity Compensation when balancing the levels of the various speakers in your audio/video system using test signals and an SPL meter.

Do not change the setting of the Proximity Compensation Switch when the VCC-5 is playing. Mute the system, then make the necessary change.

P ROXIMITY C OMPENSATION

The VCC-5’s Proximity Compensation circuit is designed to help counter the sonic effects of nearby walls and other surfaces.

1. Using good, clear dialog as a source, listen to your system with the VCC-5’s Proximity Compensation both on and off to determine which setting provides more natural and intelligible voices in your particular listening environment.

A MPLIFICATION

To maintain the seamless integration of the VCC-5 with the front left and right speakers, the center channel amplifier should be a close sonic match to the amplifier driving the main speakers. The impedance of the VCC-5 center speaker is 4 ohms so that a high current amplifier is required and it should have at least as much power as the main amplifier. With only one channel of amplification

S ERVICE

Should your VCC-5 require service, please follow these procedures.

1. Verify that the problem is in the speaker by substituting a speaker that is known to be working in place of the VCC-5.

2. Contact Vandersteen Audio, describe the problem

2. If you cannot hear a difference between the two settings or you cannot decide which setting is better, leave the switch on. In our opinion, the VCC-5 has slightly lower coloration with the Proximity Compensation turned on.

3. Once the switch has been set, it needs no further attention unless the system is moved into a different environment needed, you can bridge a good sounding, lower powered stereo amplifier into mono. To prevent system damage from power line fluctuations or other unpredictable phenomena, all the amplifiers in an audio/video system should be turned off when the system is not being used.

M AINTENANCE

The appearance of the VCC-5 can be preserved by observing a few precautions and performing some simple maintenance. The grille cloth on the VCC-5 can be vacuumed using a brush attachment that will not snag the cloth. The top should be treated as a piece of fine furniture. The wood veneers are oiled at the factory and can be maintained with an occasional light application of Pledge or a similar product.

Care should be taken that objects that could mar the finish are not placed on top of the speaker. Do not expose the speaker to excessive heat, sunlight or moisture, which can damage the fit and finish of the veneer.

A Personal Note

I have been doing volunteer work for several years with elderly people with severe hearing losses, and I have seen the frustration and anger that are brought on by these losses. We now know that many of these people developed their hearing problems because of exposure to high noise levels when younger.

Many home stereo systems, as well as audio/video, personal, and automobile sound systems are capable of volume levels potentially damaging to your hearing. Please use common sense, and listen to your music and movies at safe levels now so you will still have the ability to hear and enjoy them in the future.
