ABSTRACT:
A sound repeater unit is to be used with an audio input equipment, such as a cassette or video tape recorder, and an audio output equipment, such as a television set or a loudspeaker. The audio input equipment has a control unit which is actuated so as to operate the audio input equipment in a paused state. The sound repeater unit includes a pause control circuit receiving an activating signal from the control unit and a programmable signal repeating circuit controlled by the pause control circuit so as to record continuously an audio frequency output of the audio input equipment while overwriting a previously recorded audio frequency output of the latter. The pause control circuit further controls the signal repeating circuit so as to output repeatedly a portion of the audio frequency output, which portion was recorded within a predetermined time period immediately before the audio input equipment was paused. The pause control circuit further controls a switch so as to send the audio frequency output directly to the audio output equipment when the audio input equipment is in the normal operating state and so as to send the output of the signal repeating circuit to the audio output equipment when the audio input equipment is paused. The audio output equipment has a repeating sound output when the audio input equipment is in the paused state.
