IK Multimedia Opto CompressorOptical compression has a special sonic character that audiophiles can truly appreciate. The technology behind its behavior and the way it achieves gain reduction is so ingenious and at the same time quite simple: the core of the circuit is an electro optical attenuator, whose light source intensity is directly proportional to the level of the incoming signal. The second part of the gain reduction circuit is a photoconductive cell, which reads the
