Abstract

PURPOSE:To set a recording level invariably within a proper range by automatically decreasing an output level by detecting the arrival of an excessive input in advance. CONSTITUTION:A sound signal inputted from signal input terminal 1 is passed through delay circuit 3 and then brought under the level control of level control circuit 5 before being led to signal output terminal 6. Level comparing circuit 4 compares the input signal level from signal input terminal 1 with a set level from permissible input setting terminal 2 and, when the input signal exceeds the set level, generates and applies a control signal to level control circuit 5, which attenuates the sound signal delayed by delay circuit 3 gradually to set it within a permissible input range.
