Designed To Be Mounted In A Single-Gang Wallswitch Box

Leviton’s Decora Strauss Transformer-Free 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" sound) is often the volume control itself, because the audio transformers (AKA: autoformers) used in conventional controls can actually filter the 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. Moreover, the Decora Strauss Transformer-Free Volume Controls eliminate the problem of "saturation" 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.

  • Features Decora 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 autoformers to preserve audio signal purity
  • Detachable cable connector is compatible with all standard speaker wire sizes (14-18 gauge)
  • Decora designer styling adds an elegant touch to any decor
  • Can be used outdoors when mounted with any compatible Decora all weather cover
  • Provides the ability to adjust the volume of a pair of stereo speakers within a single listening zone
  • Designed to be mounted in a single-gang wallswitch box
  • Connector type: 0.200" eight pin in-line straight Phoenix plug with screw terminals (included)

Note: Wallplate not included.

Leviton Architectural Edition Products

An entertainment system is like a chain – it can only be as strong as its weakest link. The Leviton Architectural Edition series of products was developed to make sure that every link in the system:volume controls, distribution and connection components, even multi-room amplifiers have no weak points and are as "state-of-the-art" in performance as the systems’ speakers. The Leviton Architectural Edition is a complete solution for entertainment system designers and installers.

Leviton’s award-winning System Matching module and Strauss Transformer-Free volume controls use advanced aerospace technology to deliver ruler-flat frequency response to every zone of a multi-room audio system. The Architectural Edition multi-room audio amplifiers combine advanced audio engineering, high-current performance and tremendous value in a single low-profile chassis that delivers superior multi-channel amplification to meet the needs of the most demanding residential multi-zone systems. The advanced circuit engineering inside Leviton’s home theater and multi-room wallplates means that audiophile-grade connectivity can be easy and quick to install.
