Abstract

PURPOSE:To secure an increment for the low band with no distortion, by applying the signal with an increment received for its low band to the original signal with its low band cut through a low-pass filter. CONSTITUTION:The low band is increased through the low-band increasing circuit 2 for the input signal applied to the input terminal 1, and the amplitude of the input signal is limited by the limiter 5. Then the high band of the output is cut by the low-pass filter 6, and at the same time the low band is cut by the high-pass filter 7. The cut low band is added with the output of the filter 6 through the adding means 8 and then supplied to the speaker 4 after amplified by the power amplifier 3. As a result, the low band characteristics can be enhanced, at the same time preventing the low-band signal from exceeding the low-band allowance input of the speaker.
