In an output control device which controls an amplification factor of an amplifier in response to an input signal and a fade control signal to carry out a fade operation of an output signal, such as a fade-in or a fade-out operation, a level control signal is produced to widely control output levels of the output signal. A plurality of timing signals are produced from either the fade control signal or the level control signal and are selected in response to the level control signal and are selected in response to the level control signal to determine a combination of the timing signals. The amplification factor is controlled by the combination of the timing signals to change the output levels over a wide range by varying the combination of the timing signals from one to another.
