PURPOSE: An input apparatus a reproducing apparatus and a sound volume adjusting method are provided to set to a desired physical amount by fine changing a physical amount slowly without user's mode switching operation after a physical amount had been coarsely changed to and reached near a desired physical amount at high speed by switching a coarse adjustment mode and a fine adjustment mode in which a physical amount is increased and decreased based on rotation speed of a control rotated by a user. CONSTITUTION: An input apparatus(100) connected to an antenna(101) includes a tuner(102) for receiving audio signals, a selector(103) for receiving the audio signals from the tuner(102), an analog audio input terminal(104), a system controller(120), an analog-to-digital(A/D) converter(105) and a digital signal processor(DSP)(106). The selector(103) selects one among the audio signals under the control of the system controller(120) and outputs the selected audio signal to the A/D converter(105) for converting into a digital audio data. The digital audio data converted by the A/D converter(105) is supplied to the DSP(106) for appropriately processing a sound volume adjusting.
