1. An audio apparatus, comprising:
a plurality of operation units; and
a controller configured to set one of the plurality of operation units as a master and another as a slave, and to cooperatively operate, in response to an operation of the master operation unit, the slave operation unit while maintaining a level difference with the master operation unit, wherein
when an operation value of at least one of the plurality of operation units has reached a maximum or a minimum, the controller stores a level difference at that point of time in a memory, temporarily cancels a cooperation between the operation unit that has reached the maximum or the minimum and the master operation unit, and allows an operation of the master operation unit and an operation unit that has not reached the maximum or the minimum, and, when the master operation unit is operated in a reverse direction and a level difference between the master operation unit and the operation unit that has reached the maximum or the minimum matches the level difference stored in the memory, the controller recovers the cooperation between the operation unit that has reached the maximum or the minimum and the master operation unit.
