TROUBLE SHOOTING

Your VR dealer should have the necessary resources to investigate any problems you may experience when setting up a world class reference system. However, if you find that you need specialized help, either in acoustical or electronic interactions not well understood by your dealer, please don’t hesitate to contact the factory by emailing your request to: albert@vonschweikert.com. A qualified engineer will assist you with any problems you are experiencing in achieving world class sound.

BRIGHTNESS: A very common problem is brightness, and is wrongly attributed to the speakers since they are the apparent source of all sound. Some of the causes of brightness are:

1.Powerline Noise. Can be ameliorated with a proper line conditioner.

2.Cable Resonance. Too many brands of different cables which interact improperly. Switch interconnects, including the digital cable, to a different brand.

3.Digital Noise. Use a powerline filter on DAC only. Many times the harshness is created by digital noise bleeding into the preamp, so don’t put the preamp on the same filter as the DAC.

4.Lack of Proper Break-in. Please break speakers in 300 hours with loud music.

5.Source Material. Unfortunately, most commercial CD’s are bright! Try using the Green Felt Pen and the various CD treatments available, they work like magic.

6.Transistor Sound. Older transistor gear is bright and lacks depth. Invest in newer gear.

7.Dirty Connections. Proper maintenance of a system requires cleaning of all RCA connectors once a month; don’t forget to clean the AC plug prongs. Tube sockets and pins need to be cleaned as well, and is a source of tube glare, along with tube deterioration itself. See your dealer for cleaners.

8.Cold Equipment. The entire system must be left on (excluding tube amplifiers) continuously for best sound quality. Cold equipment, especially transistor preamps and DAC’s, sound thin, sterile, and lack depth and dimensionality. Cold transistor amplifiers sound harsh, lacking depth. Most experts recommend leaving the equipment on to avoid the damage associated with cold turn-on, since the most wear to the electronic components in an amplifier results from the inrush of current from the wall into a cold part. Once the unit is left on, the voltages and temperatures stabilize, resulting in better sound and component life. The electric bill will not reflect a huge price difference, as electronics at idle do not use much electricity (other than Class A amplifiers and tube amps).

9.Too Much Rear Ambience Driver Level. Turn down the rear driver if system is too bright.

10.Room Effects: Boomy Bass, Harsh Highs. Not many audiophiles realize how important their room acoustics are to the overall soundfield. No matter how good the speaker system and driving electronics, the room will have great influence over the final sound, whether for better or worse!

Rooms can add or subtract bass response, but correct tuning and placement can ameliorate these problems. See BASS TUNING section above.

Harsh highs can be created by echoes resulting from large wall surfaces with unbroken surfaces. If you can hear any echo when clapping your hands, you will need to use some room treatment products.

Many books have been written about room acoustics, and there is not enough space in this manual to give detailed information on how to do it right. However, the general rule is to use 50% absorptive/50% reflective ratios when covering the room’s surfaces, such as carpeting, drapes, stuffed furniture, bookshelves filled with books, records, etc. It is helpful to damp the first reflection points,

VR-5 specifications

The Von Schweikert Audio VR-5 stands as a true testament to high-fidelity audio engineering, attracting audiophiles with its impeccable sound reproduction and innovative design. This loudspeaker is part of Von Schweikert's acclaimed VR series, consistently lauded for its advanced technology and precision craftsmanship, which together create an immersive listening experience.

At the core of the VR-5's design is its unique three-way, four-driver configuration. This setup includes a large woofer, a midrange driver, and dual tweeters, each meticulously engineered to deliver a specific frequency range. The woofer is designed to produce powerful bass, capable of extending well into the lower frequencies, while the midrange driver excels in rendering vocal clarity and scale. The dual tweeters ensure that high frequencies are crisp and detailed, providing a sense of airiness and openness to the overall soundstage.

One standout feature of the VR-5 is its proprietary V-Frame design, which minimizes resonances that can color sound. This design innovation, combined with high-quality materials, lends the speakers superior structural integrity, ultimately resulting in more accurate audio playback. The use of advanced cabinet construction techniques, including extensive internal bracing, ensures that unwanted vibrations are kept at bay, allowing listeners to experience music as it was intended.

Additionally, the VR-5 incorporates advanced crossover networks that contribute to seamless integration between drivers. These crossovers employ state-of-the-art components designed to preserve signal purity and maintain phase coherence, further enhancing the fidelity of sound reproduction. The result is a coherent sonic image where instruments and vocals occupy defined positions, enriching the spatial characteristics of any recording.

Another key characteristic of the VR-5 is its ability to adapt to different room acoustics. Featuring adjustable rear bass ports and a customizable crossover frequency, users can fine-tune the speaker’s performance to suit their specific environment. This flexibility ensures that audio enthusiasts can enjoy an optimal listening experience, regardless of their space.

In summary, the Von Schweikert Audio VR-5 is a highly regarded loudspeaker that brings together state-of-the-art engineering, innovative design, and sophisticated technologies. With its three-way driver configuration, robust construction, advanced crossover networks, and room adaptation capabilities, the VR-5 offers an exceptional listening experience for even the most discerning audiophiles.
