Abstract
In a television apparatus having a television receiver, a video tape recorder for recording and reproducing video and audio information included in a received television signal and being susceptible to distortion of the recorded video information when subjected to vibrations at substantially a predetermined mechanical resonant vibration frequency, speakers for audibly reproducing the audio information of the television signal, and a single cabinet containing the television receiver, the video tape recorder and the speakers so that the video tape recorder is influenced by vibrations generated in response to operation of the speakers; an audio signal processor which acts on the received and reproduced audio information to provide an audio output signal for driving the speakers includes a suppression circuit operative in at least the recording mode of the video tape recorder for relatively suppressing at least a component of the audio output signal having substantially the predetermined mechanical resonant vibration frequency.
