ALT-126R 126 Watt Impedance Matching Volume Control

The ALT‐126R is a premium wall‐mounted volume control designed to allow easy, intuitive control of the volume of any audio system from single‐room installations to whole‐house distributed audio systems. Its high quality autoformers and other components are designed to attenuate the audio, without adding extra artifacts or taking away from the listening experience in any way. The impedance matching design allows multiple speakers to be connected to the same amplifier without compromising the system design. The UL/CSA certification and limited lifetime warranty bring the peace of mind that demanding customers desire in their installed audio systems.
