PURPOSE:To recognize the present state of a normal mode during a data setting mode by displaying a display related to a pressed operation key on a display part only for a fixed time in place of a display related to the data setting mode. CONSTITUTION:An infrared pulse signal emitted from a remote controller 50 is modulated by a command corresponding to the operation of the remote controller 50. A signal from a photodetection part 15 of a center unit 10 is decoded, a command in the optical signal is decoded and when the command is the setting data of acoustic correction including crossover, the setting data are transferred to an acoustic correcting means DSP 20. When there is any key input from either the remote controller 50 or an operation part 13 during the various modes of crossover, position, CD and tuner and it is discriminated that the continuing time of the key is longer than any press prescribed time, under the control of a CPU 12, the display related to the pressed operation key is displayed on a display part 14 only for the constant time. |
