PROBLEM TO BE SOLVED: To more easily set an adjustment value corresponding to a real sound field than the case that a user individually adjusts various adjustment values.SOLUTION: A distribution device 20 arranged in a concert hall is configured to transmit adjustment data for reproducing the sound filed of the concert hall to terminal equipment 10 of a user who is present in the concert hall by short-range radio communication. The terminal equipment 10 stores the adjustment data transmitted from the distribution device 20. When a user comes home, the terminal equipment 10 transmits the stored adjustment data to an amplifier 30. The amplifier 30 stores the adjustment data transmitted from the terminal equipment 10. The amplifier 30 performs acoustic processing to an audio signal on the basis of the adjustment data such that the sound filed of the concert hall is reproduced, and outputs the audio signal subject to the acoustic processing to a speaker.SELECTED DRAWING: Figure 1 |
