Then, the performer P on the stage turns on the controller 30 and selects and operates the switch of the adjusting device corresponding to the desired microphone and speaker. For example, the switch 33D of the adjusting device 20D corresponding to the microphone MC4 and the speaker SP4 used by the performer P is operated.

  Then, the ID selection unit 34a selects an ID corresponding to the operated switch 33D from the ID registration unit 32 and outputs it to the signal generation unit 34b. In the signal generation unit 34b, transmission data is generated based on the input ID, and this is transmitted from the transmission unit 35. In the adjustment devices 20A to 20D that have received this (step 402), the ID determination unit 23b determines whether or not the ID identified by the signal identification unit 23d matches the ID stored in each ID storage unit 22. Determination is made (step 403). In the adjusting devices 20A to 20C that do not correspond to the ID, since it is determined that the IDs do not match, the permission unit 23c does not permit the adjustment and no adjustment is performed (step 409).

  In the adjustment device 20D corresponding to the ID, since it is determined that the IDs match, the permission unit 23c permits the adjustment (step 404). When the performer P on the stage inputs desired adjustment values for each frequency band by operating the slide volume 31a in the controller 30 while monitoring the sound from the speaker SP4, these are multiplexed in the multiplexer 31b. Then, it is converted by the A / D converter 31c and output to the signal generator 34b. In the signal generation unit 34b, transmission data is generated based on the input ID, and this is transmitted from the transmission unit 35.

Are adjusted and output from the speaker SP4. Further, when another performer transmits the ID of another adjusting device (for example, 20A) from the controller 30 in the same manner as described above, the adjusting device that has received the ID (step 407) does not match the ID. Since the permission unit 23c in 20D, 20B, and 20C does not permit the adjustment, the adjustment is limited (steps 403 and 409), and the adjustment unit 20c permits the adjustment for the adjustment device 20A having the same ID (step 403). , 404), the adjustment is performed in the same manner as described above (steps 405 and 406).

  It should be noted that the adjustment in the adjustment device that has already been permitted to be adjusted can be continued (step 406) as long as no termination instruction is input by switching the switch or turning off the power in the audio adjustment console 40 (steps 408 and 410). The adjustment device that can be adjusted by receiving a new ID is switched (step 407). Adjustment is restricted for an adjustment device that does not receive its own ID (step 409). Then, when the above termination instruction is input (steps 408 and 410), the processing is terminated.

[Effect of the embodiment]
According to the present embodiment as described above, the performer P uses the controller 30 alone to perform the speaker P from the stage ST with respect to the adjustment unit 20 installed on the side of the audio adjustment console 40 away from the stage. (For example, SP4) is monitored remotely, and the remote control is used to perform adjustments such as attenuating the frequency band as a resonance point or amplifying a specific frequency band to increase the clarity of the performer. Can do. Therefore, it does not take time to operate while communicating with the operator M, and the performer P can make an accurate adjustment based on his / her own judgment.

  Further, since the desired adjustment devices 20A to 20D can be selectively switched and operated based on the identification information incorporated in the communication signal from the controller 30, the signals are output from a plurality of speakers SP1 to SP4. Conveniently, the audio can be adjusted by the single controller 30 in the desired order. In particular, since the slide volume 31a provided in the controller 30 can be used in each of the adjustment devices 20A to 20D, the controller 30 can be reduced in size. Further, since a plurality of switches 33A to 33D for selecting the adjusting devices 20A to 20D are provided for each of the adjusting devices 20A to 20D, switching can be performed quickly.
