摘要： A magnetic tape recording signal level automatic adjustment device includes: a reproduced signal level attenuator responsive to an attenuation changeover instruction for attenuating the level of a reproduced signal from a PCM audio signal reproduction device by a predetermined quantity; and an attenuation controller responsive to a sampling instruction for comparing the reproduced signal level with a reference value and outputting the attenuation changeover instruction when the reproduced signal level exceeds the reference value.
