PROBLEM TO BE SOLVED: To obtain appropriate sound field by automatically applying headphone use three-dimensional sound field processing to a selected source signal in the case of using a headphone. SOLUTION: In the case that a headphone plug is inserted into a headphone jack 5P, a CPU 7 recognizes the connection of a headphone from a detection signal from a headphone detection section 35 to conduct three-dimensional sound field processing for the headphone. Simultaneously the CPU 7 sets a signal selector to select a headphone amplifier. Thus, the sound field processing for the headphone is applied to the selected source signal and the signal is amplified by the headphone amplifier and the amplified signal is sounded from the headphone. |
