The Keene in-wall amplifier (KLAB20) is a unique product ideal for use in multi-room audio installations. It is a high quality stereo audio amplifier that is built into a standard sized UK double gang back box. It provides 20 Watts per channel RMS of amplification (when using 4 Ohm speakers) eliminating the need to make space for a conventional amplifier. It draws its own power from an externally located mains adaptor and control is by infra red remote.
The Russound ALT-126R is a wall-mounted 126 watt, peak, 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 Russound ALT-126R allows you 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.
