Abstract
An output level control apparatus which operates according to a reproduced signal level from a digital recording apparatus. The output level control apparatus includes a signal level detection device which compares the level of the reproduced signal with a predetermined level to decide if a level of the reproduced signal should be changed. The output level control apparatus further includes a device which attenuates the level of the reproduced signal to a suitable level when the signal level detection device determines that the reproduced signal should be changed.
