Patent ID: 8401680

Claim:
An amplifier system including a plurality of amplifiers and an amplifier control apparatus interconnected via a network, each of said amplifiers comprising: an input section to which is inputted a sound signal; a processing section that amplifies the sound signal inputted to said input section; an output section that outputs the sound signal amplified by said processing section; a storage that stores a set of parameters, for controlling the amplification by said processing section; and a changing section that changes a value of a parameter stored in said storage and transmits a report notifying the change of the parameter to the amplifier control apparatus, said amplifier control apparatus comprising: a display device; an input device that receives user's operation; a storage that stores a plurality of sets of parameters corresponding to the plurality of amplifiers, each of the parameter sets having data structure and values to the parameter set stored in the corresponding one of said amplifiers; an update section that receives the report from one of said amplifiers and updates the parameter set corresponding to the one amplifier in said storage on the basis of the report; a grouping section that groups said amplifiers into groups in response to a grouping operation received by said input device; a first display controller that, in response to an amplifier selecting operation received by said input device, selects one of said amplifiers, and displays an amplifier detail screen having an element thereon for the selected amplifier on said display device, wherein said first display controller takes out a parameter corresponding to the element from the parameter sets corresponding to the selected amplifier stored in said storage and displays the value of the parameter via the element on said display device; and a second display controller that, in response to a group selecting operation received by said input device, selects one of said groups and displays a group detail screen having an element thereon for the selected group on said display device, wherein said second display controller takes out parameters, corresponding to the element, from individual ones of the parameter sets corresponding to the amplifiers in the selected group stored in said storage, detects a maximum value and a minimum value from among the taken-out parameters and displays the detected maximum and minimum values via the element on said display device.
