Leviton Decora Strauss Transformer-Free Volume Controls (SGVST-00W / SGVSM-00W) — Specification Bulletin

Specification bulletin for Leviton Decora® Strauss™ Transformer-Free™ Volume Controls (SGVST-00W) and Transformer-Free Impedance Matching Volume Controls (SGVSM-00W) — audio-grade Cermetile resistor volume controls that avoid the frequency coloration of traditional autoformer-based controls.

Application

Leviton's Decora Strauss Transformer-Free and Transformer-Free Impedance Matching Volume Controls, combined with premium installed speakers, can be used to design a no-compromise 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 (often perceived as a "muffled" sound) is frequently the volume control itself, because the audio transformers (autoformers) used in conventional controls can filter bass and treble frequencies. The Decora 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. They also eliminate the "saturation" problem associated with conventional volume controls, handling the full peak output power of any consumer-grade amplifier on the market instantaneously.

The Decora Strauss Transformer-Free Matching Controls are available in two versions: regular and Impedance-Matching.
