Product Details

Leviton's DECORA (R) brand Strauss Transformer-Free and Transformer- Free Impedance Matching Volume Controls, combined with premium installed speakers, can be used to design a no compromise installed multi-room entertainment system that delivers the best reproduction possible from today's ultra-wide bandwidth digital sources. In multi-room distributed audio systems, the source of undesirable speaker coloration (usually perceived as a "muffled-inch sound) is often the volume control itself, because the audio transformers (AKA: auto formers) used in conventional controls can actually filter the bass and treble frequencies. The DECORA (R) brand Strauss Transformer-Free Volume Controls use audio-grade Cermetile resistors to change volume levels while leaving the audio signal unaffected, resulting in ruler-flat frequency response across the entire audible frequency range. Moreover, the DECORA (R) brand Strauss Transformer-Free Volume Controls eliminate the problem of "saturation-inch associated with conventional volume controls with their ability to instantaneously handle the full peak output power of any consumer-grade amplifier on the market today. The award-winning DECORA (R) brand Strauss Transformer-Free Matching Controls are available in two versions: regular and Impedance-Matching. DECORA (R) brand Strauss Transformer-Free Impedance Matched Volume Control

* DECORA (R) brand slide control with precision 12-positon switch (including full OFF position)

* Transformer-Free attenuation technology ensures linear frequency response, signal integrity and high power handling ability

* Cermetile resistors replace conventional auto formers to preserve audio signal purity

* DECORA (R) brand designer styling adds an elegant touch to any décor

Does not funtion as described and no one knows why!!

Reviewer:  John D

My builder pre wired my home for whole house audio and used this product. I have tried several speaker configurations 1, 2 and 3 pairs all 8 ohm speakers connected to each volume control with monster CI Pro 14/4 cable directly to a 100Watt amplifier and still gives a muffled audio signal. all of my cable runs are under 75 ft.

I have replaced them with transformer based Volume controls and they sound fine. I have also purchased one of the SGVST-M volume controls and it sounds GREAT. I had taken one of the SGVSM volume controls and connected it to a home receiver and had 2 feet of speaker cable between the receiver and speakers and it still gave muffled audio to the speaker. I then did the same with the transformer based and the SGVST and both worked great.

I had picked this product because it is supposed to not distort the audio signal like a transformer, however it does and distorts to a much higher level than a transformer.

This product does not work as described..
