The remote control processing unit 2256c receives a control command operated by a user from the main control unit 221, retrieves a control command corresponding to the received control command from the memory unit 2256a, and sends the control command to the retrieved control command. The corresponding remote control operation command is transmitted to the corresponding sound source generator 210 through the digit link interface unit 2256b to remotely control the corresponding sound source generator 210.

Therefore, the main control unit 221 controls the remote control operation command of the external sound source generator 210 through a management program for controlling the key control unit 2241 of the front control unit 224 or the public address system of the management computer 300. When a corresponding control command is inputted and set, and transmitted to the remote control processing module 2256, the remote control processing unit 2256c receives it and transmits a control command corresponding to the received control command to the memory unit 2256a. ), And transmits a remote control operation command corresponding to the searched control command to the corresponding sound source generator 210 through the digital link interface unit 2256b to remotely control the corresponding sound source generator 210. Therefore, the same operation as that of the remote controller can be performed with respect to the external sound source generator 210 through the remote control processing module 2256.
