Abstract
An audio systemhas a plurality of audio sources-for outputting audio signals different from each other. A coefficient deviceadjusts the gain of the audio signal output from one of the audio sources. A nonvolatile memorystores, as internal gains, gains to be set to the coefficient device in correspondence with the audio sources. When a switch changeover sectionselects one of the audio sources, the CPUreads from the nonvolatile memory the internal gain corresponding to the audio source selected, and sets the internal gain to the coefficient device.
