PURPOSE:To easily make the total frequency characteristic of an entire audio device coincident to a desired characteristic by providing a display mode partial changing means to change display modes in a band to be changed by the operation of a frequency characteristic change operating means and in the other band concerning the frequency characteristic display of a frequency characteristic display means corresponding to the operation of the frequency characteristic change operating means in a frequency characteristic change device. CONSTITUTION:A microcomputer 26 is equipped with a CPU, ROM and RAM connected by a bus and executes the variable control of a graphic equalizer characteristic, display control of the characteristic and spectrum analizer display control corresponding to the operation of a key operation part 28 based on a prescribed program stored in the ROM. On the other hand, the microcomputer 26 is equipped with a function as the display mode partial changing means to execute the display mode partial change control for changing the display mode on an FL tube display 30 in the band, to which loudness control is executed, and the other band according to a loudness control operation on the side of a control amplifier and concretely, in the band controlled in loudness, inverted display control is executed for ON/OFF segments. |
