ABSTRACT:
An audio signal output apparatus is provided for simultaneously outputting audio signals contained in a multiplexed audio signal via a loudspeaker and a headphone. The audio signal apparatus comprises a first volume/balance adjuster for adjusting volume and balance of an audio signal output via the loudspeaker, and a second volume/balance adjuster for adjusting volume and balance of an audio signal output via the headphone. A switch provides a first audio signal included in the multiplexed audio signal to the first volume/balance adjuster and simultaneously provides a second audio signal included in the multiplexed audio signal to the second volume/balance adjuster. A microcomputer controls volume and balance adjustment operations of the first and second volume/balance adjusters and controls the operation of the switch.
