PURPOSE:To obviate the trouble of setting and to reduce the space of the equipment by operating the setting data of acoustic correction by a remote controller as well along with normal operations such as the selection of a sound source or the setting of sound volume. CONSTITUTION:An acoustic correcting means DSP 20 performs the acoustic correction to an audio signal sent from a center unit 10. An infrared pulse signal emitted from a remote controller 50 is modulated by a command corresponding to the operation of an operation part inside the remote controller 50. A signal from a photodetection part 15 at the unit 10 is decoded by a CPU 12, and a command contained in the optical signal is decoded. When the command from the remote controller 50 is the setting data of acoustic correction including crossover, the CPU 12 transfers the setting data to the DSP 20. |
