KLAB20 Amplifier with White Front (with UK power supply)
A 20W (RMS per channel) amplifier that fits flush to the wall!
The Keene K-LAB-20 is a unique product ideal for use in multi-room audio installations. It is a high quality stereo audio amplifier that's built into a standard sized UK double pattress. It provides 20W (RMS per channel) of amplification 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.
