ABSTRACT:
In an apparatus for analog recording having a dynamic compressor for amplifying an analog input signal wherein the gain varies in response to an applied control signal, there is provided an improved limiter for providing a gain reducing influence to the applied control signal to control the gain to a generally single-valued function of the analog input signal for analog input signals having an amplitude within a select range.
