Claims

[Scope of utility model registration request]

(1) In a graphic equalizer that can change the electrical characteristics of an input signal by operating an operating section, the operating section is provided with a light emitting body capable of emitting light of a plurality of colors,
The color emitted by the light-emitting body is made different depending on whether the operation part is located above a reference level or below the reference level, and when the operating part is located near the reference level, a composite color of the emitted light color is displayed. A graphic equalizer characterized by the following.

(2) The graphic equalizer according to claim (1) of the utility model registration, in which the luminous body changes the brightness according to the position of the operating unit with respect to the reference level.
