PROBLEM TO BE SOLVED: To reliably facilitate version management of firmware of each device when an acoustic signal processing system used in a concert hall or the like is constituted of a plurality of devices connected via a network. SOLUTION: Each of a plurality of devices belongs to any one of a plurality of device groups and each of partial devices in each device group includes an interface (partial bridge) for communicating with the other device group. A check box 182 is provided for designating whether firmware of the partial bridge can be updated. Thus, while holding firmware relating to the partial bridge in a version communicable with the other device group, the other firmware can be automatically updated, and firmware of a different version can be applied for each device group.
