126W Volume Control, Decora plate

126W Volume Control, Decora plate ALTX-2D

The ALTx-2D is a wall-mounted 126-watt volume control with a Decora®-style wall plate. It connects between the speaker outputs of an amplifier or receiver and a pair of speakers.

Using Ultra-Match technology, the ALTx-2D allows installers to easily match the load of multiple speaker pairs to the amplifier impedance without the need for a speaker selector or other impedance-matching equipment.

All Russound volume controls are made with precision autoformers for high-fidelity sound, excellent frequency response, no heat buildup, and maximum power transfer from the amplifier to the speakers.

Russound ALTx-series volume controls conform to UL and CSA standards to assure that they’re designed and tested for safety.
