Urei LA-22

Versatile and transparent limiter/compressor with several advantages. The gain reduction cell can be controlled by a peak detector and a variable detector at the same time in varying amounts, according to the front panel settings. There is also an equalizer that can be internally tied to the compression circuit for band specific dynamic notching. There is an upward expander mode which can also work as a dynamic boost filter. The equalizer output is available as a discrete output, and is functional in all modes. To use this equalizer for frequency-dependent ducking (conventional side-chain limiting), you must patch the equalizer output to the side-chain input, and set the compressor mode to "wide band."
