PURPOSE:To simply change the signal flow in the processor by using a controller so as to control the signal flow in a signal processing section so as to be a flow selected by the key operation thereby displaying the signal flow in the signal processing section. CONSTITUTION:A signal processing section 11, a controller 10 controlling the signal processing section 11, a key 30 sending an operation command to the controller 10 and a display section 17 displayed attended with the control of the signal processing section 11 by the controller 10 are provided. Then the controller 10 is used to obtain a signal flow selected by the key 30 among plural preset flows in the signal processing section 11 and the signal flow of the signal processing section 11 is displayed by the display section 17. That is, since the signal flow is selected and set at the signal processing section 11 depending on the key 30, the signal flow is changed simply depending on the operating state and the signal flow to be set is displayed on the display section 17, then the signal state is discriminated easily. |
