Stereo Class A optical compressor designed for tracking, mixing and mastering, delivering transparent dynamic control while preserving depth, stereo image and transient detail. Its dual-servo optical design bridges the smooth character of classic opto compressors with the speed and precision of VCA designs, making it equally capable of subtle levelling, peak limiting or heavy, creative compression.
