Abstract: An adaptor for a connector to be interposed between a first terminal unit having many contact pieces and a second terminal unit having many contact pieces that are used for input/output of a video signal, an audio signal, and a signal associated therewith. A first connecting portion has many contact pieces corresponding to the many contact pieces of the first terminal unit, respectively, and is so shaped as to be connectable to the first terminal unit. A second connecting portion has many contact pieces that correspond to the many contact pieces of the second terminal unit, respectively, and are connected to the respective contact pieces of the first connecting portion. The second connecting portion is so shaped as to be connectable to the second terminal unit. Conductive contact pieces are connected to predetermined ones of the many contact pieces of the first and second connecting portions, and are to be connected to pin plugs or pin jacks.

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.
