Overview & walkthrough
Invisible gain riding
Optical compression won because you can't hear it working — only that the vocal suddenly sits.
OptoRED models the classic American optical unit: smooth, musical, artifact-free gain riding for vocals, bass, drums and busses.
A lo-cut filter and sidechain control what triggers the compression; autogain and wet/dry mix keep the workflow honest and parallel-ready.
What's inside
Smooth. Musical.
Invisible.
Optical attenuator
The signature opto curve — fast enough to catch, slow enough to breathe. Low ratios with autogain make it a natural bus glue.
Sidechain & lo-cut
Keep low end from triggering the detector for clean, punchy drum compression, and blend parallel with the wet/dry mix.
