A signal level display unit which makes adjustment for correcting of deviation unnecessary and enables cost reduction. An input analog audio signal 26 is divided into seven signals having different frequency bands, converted into digital signal by an A/D converter 22, input to a display controller 25, and temporarily stored in a storage unit 32. A preset recovery time which is input to the display controller 25 through an A/D converter 28 is also stored in the storage unit 32. The value of each signal newly input from the A/D converter 22 is compared with the current value stored in the storage unit 32. When the value of a newly input signal is higher than the current value, the value displayed by a liquid crystal indicator 23 is immediately renewed. On the other hand, when no signal having a higher value than the current value is input, the displayed value is renewed after the preset recovery time stored in the storage init 32 has elapsed.
