All the OG controls
The Shadow Hills Mastering Compressor Class A is no stranger to dual-stage compression, and now your home studio can reap its benefits. The Mastering Compressor Class A encases your tracks with controlled and musical tonality, achieved through both Discrete or Optical controls (or even simultaneously). Whether you’re adjusting the Threshold and Gain settings of the Optical section or fine-tuning the Ratio, Attack, and Release of your signal via VCA Discrete controls, chasing that perfect dynamic shape and compression response is as effortless and satisfying as it gets.
You’ve also got your choice of three output transformers, just like on the original! With Nickel, you’ll notice extraordinarily smooth and refined delivery at both frequency poles, making it the perfect candidate for those mellower tracks. Switch to Iron, and experience a bit more musicality across the board, highlighted by low end boost, Class-A even-ordered harmonic distortion, and a vibrant top end. Or select Steel, and emphasize a low-end boost with phenomenal detail and responsiveness!


What's different about Class A?
Brainworx painstakingly modeled every aspect of the limited edition Shadow Hills Mastering Compressor Class A — and we mean every aspect! Right down to the handwired compressors, Mogami cabling, and Lundahl input transformers, this plug-in packs a seriously high-grade punch thanks to Brainworx's patented Tolerance Modeling Technology. And speaking of punch, the resulting sound of the Mastering Compressor Class A is a much punchier VCA than the standard version, offering a thicker tone with greater depth and dimension for your mix.
Below the main unit, Brainworx included the Mastering Compressor Class A's coveted Extra Unit. This add-on to the limited edition compressor supplied TMT, Mid-Side processing, Mono-Maker, Stereo Width, Parallel Mix, Sidechain Filtering, Headroom, and Parameter Linking. Now, not only does your sound give off a punchier, richer, and more powerful vibe, but there are even more sculpting controls to bring your masters to the exact level you are chasing!
New features exclusive to Brainworx
In addition to the stellar original controls, Brainworx has some modern tricks to make the Shadow Hills Mastering Compressor Class A even more versatile. Parallel Mix Control enables efficient referencing to your original unprocessed signal. Additionally, an External Sidechain with Sidechain Filter keeps your mix tight and crisp, eliminating the unneeded triggering of compression by frequencies outside your ideal set range. Just open up the toolbar, and your compression extras are at your disposal.
