Smart Research C1LA 500-series Compressor

The Smart Research C1LA is a 500-series stereo compressor and limiter based on the highly successful Smart C1 mix buss compressor.

The Smart Research C1LA features all the same circuitry and settings as its sibling including the same 3 modes: Independent, Stereo Linked/Sum and Stereo Linked/DC. Improving on the classic VCA compressor design that has shaped the sound of hits music from the 80’s the CL1A features additional ratios 1.5:1, 3:1 ratios and a Limiter as well as an external mono/stereo Side-Chain input with high-pass filtering with centred frequencies ranging from 65Hz, 130Hz and 205Hz.

The Smart Research C1LA is a VCA compressor designed as a mix buss compressor to provide the final “glue” to gel a mix together while adding the unmistakable punch that has made the Smart C1 so successful. A ‘Soft’ mode includes a new compression curve reacting across a wide broad input range of 15dB for a softer compression.
