There is often a need to modify signal dynamics in a selected portion of the audio spectrum, without affecting the remainder of the spectrum. Examples are FM signal transmission, disc cutting, modification of a solo in a master tape, or the addition of a percussive quality to a program. The device described is a limiter/compressor/expander combined with a three-zone filter (20 Hz to 20 kHz) which permits a selectable high pass, bandpass, or low pass signal to enter the limiter/compressor/expander. A special three-zone filter allows for example, the bandpass to enter the limiter/compressor/expander, while the high pass and low pass segments of the spectrum go around the limiter/compressor/expander. The outputs of the limiter/compressor/expander, the high pass and low pass filters are summed together to give flat frequency response.
