Further, the direction display section has a light emitting element which is turned on when the level of the input signal is adjusted in the plus direction, and turned off when the level adjustment is performed in the minus direction.

Therefore, when the level adjustment is performed with a single light emitting element, the operation direction is indicated, and the direction of the level adjustment can be easily determined.

The direction display section is lit when the level of the input signal is adjusted in the plus direction.
And a second light-emitting element that lights up when the level adjustment is performed in the minus direction.

Therefore, when the level adjustment is performed by the pair of light emitting elements, the operation direction is indicated, and the direction of the level adjustment can be easily determined.

Further, the light emitting element is provided on a predetermined lower side of the rotary encoder.

Therefore, the lighting state of the light emitting element can be accurately recognized, and the direction of the level adjustment can be easily determined.

Further, the first and second light emitting elements are provided on predetermined lower left and right sides of the rotary encoder, respectively.

Therefore, the lighting state of the pair of light emitting elements can be accurately recognized, and the direction of level adjustment can be easily determined.
