Version 1 of the Apogee Electronics Opto-3A is an FX Rack vintage-style compressor/limiter plug-in merging optical compression performance with straightforward controls and multiple powering, routing, and monitoring modes. It can be powered by your computer’s CPU without Apogee hardware or via the DSP in Apogee Element Series or Ensemble Thunderbolt audio interfaces (available separately), making it ideal for producers, beatmakers, and audio engineers with mobile rigs or studio-based systems. When used with qualified Apogee hardware, it allows real-time printing through the Apogee Control Software, or low-latency monitoring while linked to a mirrored instance in your DAW.

With adjustable gain, peak reduction, and high-frequency emphasis, the Opto-3A offers versatility suitable for individual instruments, submixes, and stems. Utilize the dry/FX slider for simple parallel processing, and tweak the sidechain high-pass filter to prevent pronounced low frequencies from causing over-compression. View and manage your gain staging via large I/O meters, an assignable VU meter, and dedicated input and output faders. The Opto-3A supports AAX, Audio Units, VST, and VST2 plug-in formats on macOS-equipped computers.

FX Rack Features

  • Native Mode: Use Apogee FX Rack plug-ins like any standard native plug-in in your Mac-based DAW without Apogee hardware connected
  • Print Mode: Apply Apogee FX directly to the Apogee hardware input—open the FX Rack in Apogee Control, apply the desired processing, then record—FX processing is printed to your DAW track
  • DualPath Monitor Mode: Upon opening a native Apogee FX Rack in your DAW (and linking it to an Apogee hardware input), a parallel FX Rack is automatically opened in the low-latency monitoring path; changes made in either plug-in are instantly mirrored to maintain a consistent sound
