止装置。[Claims for Utility Model Registration] An input section, which is connected to the rear stage of the input section, and whose frequency characteristics are variably changed from a flat frequency characteristic to a frequency characteristic that emphasizes the mid-range in the low, middle, and high ranges. a sound quality adjustment circuit having a sound quality adjustment means for adjusting the sound quality, and a volume adjustment means connected to the rear stage of the sound quality adjustment circuit, and when the volume adjustment means is in a "low volume" state, the sound quality adjustment means has a flat frequency characteristic. The sound quality variable means and the volume variable means are interlocked so that the frequency characteristic shifts to a frequency characteristic that emphasizes the midrange as the sound quality shifts to a "loud volume" state. Audio distortion prevention device.
