PROBLEM TO BE SOLVED: To make it easy to perform the output check of a speaker connected to an amplifier, when many amplifiers are centrally controlled from an amplifier controller. SOLUTION: In the amplifier controller to control a plurality of amplifiers equipped with a solo switch which is capable of setting output ON/OFF by each processing channel ch, an operation mode is made to be capable of switching between a normal mode and a solo mode, and at the same time, in the solo mode, a specific channel ch is made to be capable of being selected as a solo output channel ch (S22), each amplifier of the object of control is made to be set so that the solo switch ON is for the output channel ch only (S25), and that the solo switch OFF is for the other output channels ch (S27). Moreover, in the normal mode, the solo switch is fixed to be ON, the setting of the solo switch output channel ch is made to be not accepted (NO in S21). COPYRIGHT: (C)2009,JPO&INPIT
