Document Type and Number:

Japanese Patent JPH0468904

Kind Code:

A

Abstract:

PURPOSE: To improve the operability by storing an inputted correction quantity, reading the correction quantity as required and setting it.

CONSTITUTION: A processing circuit 32 generates display data of a low sound frequency in response to the operation of an equalizer switch 20 and an operating knob 21 and lights a segment corresponding to a display area A based on the display data. A segment representing a correction quantity corresponding to the operation of the equalizer switch 20 and an operating knob 22 or 23 in remaining display areas B, C similarly to the case with the display area A.
