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.
Flush mount - fits into a wall
IR control - Full remote control (carrier frequency 56 KHz)
20W RMS per channel
Fully complimentary output stages with built in short circuit, open circuit, thermal and under voltage protection.

Fixed volume Installations
If required the KLAB can be configured to operate with a fixed volume output which is useful for commercial applications where a preset volume is required. If it's to be used in an environment where the volume will not need to be changed and the unit will always be on, it can also be configured to make the remote control inoperative.
