PROBLEM TO BE SOLVED: To solve a problem of the necessity of complicated operations to mutually replace a main-side source and a sub-side source. SOLUTION: A main body apparatus 11 includes: a mode selection section 41 for selecting a sound source among a plurality of sound sources; a mode setting section 42 for applying ON setting to the selected sound source; a dual mode setting section 44 for applying ON setting to a dual mode wherein a sound signal fed from other sound source (sub-side source) is outputted to a headphone 16 while outputting a sound signal from an optional sound source (main-side source) to a speaker 15; and a control section 48 for controlling the mode selection section to mutually replace the main-side source and the sub-side source when detecting a prescribed operation in the dual mode set to an ON state and for controlling the mode setting section to apply ON setting to the main-side source and the sub-side source which have been replaced.
