This was B&O’s first remote control, predating the Beomaster 2400. Known affectionately as the brick, it was very necessary as setting up a quad system required to be sitting at the centre of the four speakers. It allowed control of the volume and Beomaster source though it was not able to control any device except the Beomaster. It used ultrasonic rather that infra red waves and needed to be aimed at the Beomaster.
