PURPOSE:To effectively use a center speaker by applying a sound signal selectively to left/right speakers and the center speaker in the surround mode. CONSTITUTION:When the surround mode is selected by a button 4(24), the information is detected by a microcomputer 6 and a sound signal in response thereto is outputted from a center speaker 19. Moreover, in order to make it possible to output only a sound signal at a frequency band to the center speaker 19 by the switching system, a filter switch 11, filters 12, 13 are provided. As a result, the frequency of the use of the center speaker 19 is increased and the presence is enhanced by the filters 12, 13 and the switch 11. |
