Abstract
Abstract An audio reproducing apparatus including first and second audio signal transmission paths each applied with a plurality of audio signals. Each of the first and second audio signal transmission paths has a selector for selecting one of the plurality of audio signals supplied thereto and a level controller for controlling the level of the selected audio signal. The first and second audio signal transmission paths are connected to first and second speaker units respectively each for converting the audio signal selected by the corresponding selector and whose level is controlled by the corresponding level controller into acoustic power.
