The WALTx-2 is a weatherproof 126-watt volume control in a surface-mount PVC enclosure. It connects between the speaker outputs of an amplifier or receiver and a pair of speakers.

Designed for outdoor or wet locations, the WALTx-2 can be mounted on an exterior wall or other flat surface, as well as directly on a section of 3/4" PVC conduit. The WALTx-2 provides convenient control of your speakers with superior resistance to moisture from rain, splash, or sauna.

Using Ultra-Match technology, the WALTx-2 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.
