Since 1985 Knoll has been the world market leader for premium sound quality volume controls and stereo interfaces.

The Knoll VS150im is a twelve-position in-wall mountable stereo speaker volume control with impedance matching capability. From two to thirty-two pairs of speakers can be safely driven from one stereo amplifier using an equal number of VS150im’s. Separate impedance matching components are not required. The Knoll WT6 one stereo input to six stereo output connection strip is available to neaten the wiring of larger systems.

The VS150im stereo volume control features two multi-laminate coils designed for performance at an affordable price. Using make before break switching topology eliminates pops and click while adjusting the volume. The wall plate is a strong but aesthetically pleasing plastic and metal two piece design with a matching knob. The knob and plate are easily paintable to match most decors.

Installation is fast and easy as the detachable high current connector can be installed long before trim out. The VS150im takes a single gang and fits in almost any junction box or ring. The connector can accept 10-24 gauge wire.

A rotary knob version is available, model VC150im.
