MIA Laboratories has released the 409 Opto Compressor plug-in. Based on the principles of analog opto compressors, the 409 is designed to deliver versatile, natural and musical compression, MIA Labs says.

According to the developer, the 409 Opto Compressor plug-in uses physical modeling principles to recreate the compression characteristics of analog optical elements. MIA Labs says that the 409 can do anything from gentle, transparent compression to heavy limiting.

All the basic compressor controls are on the left: Input level, ratio (continuously adjustable), threshold, attack, release and make-up gain. The 409 also offers a dry/wet mix knob for parallel compression (Process). Some early commenters have mentioned that it would be nice to be able to drive the input gain beyond 0 dB, but that isn’t possible at this point.

To the right are two large meters, which can display the input or output levels or gain reduction, and a button for activating the external sidechain input.

Open up the extended controls, and you’ll find additional settings for shaping the sidechain signal and fine-tuning the compression response. In addition to continuously tunable high pass and low pass sidechain filters, the 409 offers damping and skew knobs, which affect the envelope response. There’s also a stereo link option, peak and RMS detector modes, a sidechain monitor button and three meter calibration settings. Finally, you can set the lookahead time using a knob on the right.

That’s a pretty comprehensive set of controls and it looks like the 409 will be a versatile compressor plug-in. At the low introductory price, I’d say that it’s worth a look!

Price and compatibility

The MIA Laboratories 409 Opto Compressor is now available for an intro price of EUR/USD 39. This offer expires on December 6, 2020, after which the price will increase to EUR/USD 129. A 14-day trial version is available.

The plug-in runs on Windows 7 or higher (64 bit) and macOS 10.7-10.14 (64 bit) in VST3, AU and AAX formats. You’ll need an iLok account for activation.
