A body device includes: a plurality of sound sources; a speaker and a headphone for outputting sound signals from those sound sources; and a mode setting unit capable of setting a single mode, in which the sound signals from one sound source are output in response to an operation from a front operation unit, and a dual mode in which, while the sound signals from one sound source are being output from the speaker, the voice signals from another sound source are output from the headphone; an external connection unit for connecting an external DVD device with the outside; and a control unit for controlling a mode setting unit so that the body device may be turned ON in the dual mode when a power ON demand signal from the external DVD device or a rear operation unit is detected.
