PROBLEM TO BE SOLVED: To provide an audio system which hardly causes distortion even if the volume is increased. SOLUTION: It is judged whether or not an emphasis specifying value is larger than a 1st prescribed value by an emphasis specifying value judging means. It is judged whether or not an amplification specifying value is larger than a 2nd prescribed value by an amplification specifying value judging means. Then, if it is judged that the emphasis specifying value is larger than the 1st prescribed value by the emphasis specifying value judging means and it is judged that the amplification specifying value is larger than the 2nd specified value by the amplification specifying value judging means, an emphasis specifying value reducing means reduces the emphasis specifying value of low and high ranges. |
