CONTROL TERMINAL DEVICE, CONTROL METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform individual or collective volume control operation on a plurality of sound output devices with high usability.

SOLUTION: A control terminal device shows on its display section an individual volume setting section which shows a volume setting state with respect to each of a plurality of sound output devices and includes an operator to variably manipulate the volume settings and a master volume setting section which includes an operator which enables the volume setting states of the plurality of sound output devices to be variably manipulated while their volume balance is being maintained. When an operation is performed on the master volume setting section, volume setting on each individual volume setting section is altered by using a value for an operable amount on each individual volume setting section which is the same proportion as that of a detected operation amount for an operable amount on the master volume setting section at the time the operation is performed. Then, a control signal which indicates setting of an altered new volume is generated, which is sent to each of the sound output devices.
