Three Mastering-grade Compressors in One

Get to know them!

Shadow Hills Industries has created Mastering Compressor so that you can get world-class dynamics control, with the sonic versatility to shape your sound via switchable output transformers. To start with, the Mastering Compressor sports stereo and dual-mono modes to fit any application, and separate Optical and Discrete compression sections for two-stage compression techniques. For your convenience, dual Hoyt meters provide signal status at a glance, and stepped attenuators make it easy to recall specific session settings. And once you've got your dynamics under control, choose from three different output transformers with their own individual sonic flavor. The Shadow Hills Industries Mastering Compressor gives you more flexibility than you thought possible with a dynamics controller.

Shadow Hills Industries Mastering Compressor at a Glance:
  • Dual compression sections for unprecedented dynamic control
  • Switchable output transformers for sonic variety
  • Premium signal path throughout
Dual compression sections for unprecedented dynamic control

The Shadow Hills Industries Mastering Compressor controls your dynamics in two stages, an optical section and a discrete section. The optical section is mostly program dependent, with just Threshold and Gain settings, and features a two-stage release time reminiscent of a famous audio leveler from the late-'60s. Use the optical section to get your dynamic range under control, and to bring up overall level.

The discrete section utilizes a VCA design, and takes over where the optical section leaves off. With precise control over ratio, attack, and release, you'll be able to fine-tune the response of the Mastering Compressor to suit any program material, for any project.

Each section can be hardwire-bypassed individually, essentially giving you three exceptional methods of dynamics control in one single compressor.

Switchable output transformers for sonic variety

You have remarkable control over the tone and vibe of your music with the Shadow Hills Industries Mastering Compressor, thanks to three switchable output transformers. Switching transformers provides a subtle but significant tonal shift, allowing you to choose the right vibe for your material. Choose from steel, nickel, or iron output transformers to get the iconic sound of different styles of analog consoles. The nickel transformer gives you a natural low end with smoothly enhanced high frequencies, outstanding for intimate acoustic recordings. The iron transformer has a natural high end with a slight boost around 110Hz, and has a Class-A output stage that only passes even-ordered harmonic distortion - very musical. The steel transformer sounds very open with a detailed and fast response, with a very subtle boost around 40Hz that helps provide rock-solid low frequencies.

Premium signal path throughout

From the custom-designed, gold-plated stepped attenuators for easy settings recall, to the custom output transformers, the Mastering Compressor's signal path is world-class all the way. And each compressor section can be hardwire-bypassed for exceptional sonic integrity when not in use.

Shadow Hills Industries Mastering Compressor Features:
  • Choose from optical compression, VCA compression, or both in series, for unprecedented dynamic control with a mastering-grade signal path
  • Optical section provides smooth, program dependent leveling, just like a classic audio leveler from the late-'60s.
  • Discrete section gives you the fast, precise sound of a classic VCA compressor
  • Sidechain frequency filter prevents frequencies below 90Hz from triggering compression for tighter-sounding mixes
  • Three selectable output transformers each have their own distinctive sonic characteristics, for unparalleled tonal control
  • Requires Shadow Hills Power Supply, not included
Experience an entirely new paradigm in dynamics control with the Shadow Hills Industries Mastering Compressor!
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
