Ｍビートキヤンセル機能付き音響機器。[Scope of Claim for Utility Model Registration] Audio equipment having a tape deck section with constant speed and high speed tape dubbing recording functions and an AM radio receiving section, in which the tape speed is set to either constant speed or high speed during dubbing recording. It is connected to a changeover switch and the output side of the changeover switch, and oscillates the oscillation frequency of the bias oscillation circuit at different frequencies corresponding to the constant speed or high speed setting position, thereby making it possible to generate beats when recording AM radio broadcasts. and a bias oscillator that eliminates beat disturbance by switching the changeover switch when disturbance occurs.
Audio equipment with M beat cancel function.
