自動録音レベル調整器。[Scope of claim for utility model registration] (a) A peak hold circuit that detects and holds the peak level of the output of a recording amplifier or a recording/playback amplifier, (b) A memory circuit connected to a comparator, and (c) A peak hold circuit. A comparator that compares the output of the circuit with the signal stored in the memory circuit and inputs the larger signal to the memory circuit and AGC circuit; and (2) adjusts the gain of the recording amplifier based on the signal input from the comparator. By inputting the maximum level part of the signal to be recorded in advance, the gain of the recording amplifier can be adjusted to the maximum recording level without clipping at the peak level of the signal to be recorded. An automatic recording level adjuster for a tape recorder, which is characterized by setting the level to .
