Meet Your mix buss’ best friend
Celebrated mix & mastering engineers like Dave Pensado, Bob Horn, and Heba Kadry rely on the sweet tubes and creamy-sounding transformers of the Black Box HG-2 to help their mixes sound louder, bigger, and punchier at the same peak level. Now, the HG-2 MS version offers mid-side processing, advanced filters, and more for even greater sonic refinement. This new plugin has also received Brainworx patented Tolerance Modeling Technology (TMT)*.

“MS” in many ways
The HG-2 MS is a Mid/Side version of the acclaimed HG-2. But it’s more than that. It also includes dedicated Mono mixing and Stereo buss versions, and now delivers More Saturation options and a wider variety of colors than ever before thanks to its new filter section. Select from highpass, lowpass, bandpass, and bandstop filters to tailor your saturation separately for each channel.

Sweeten your audio in mono, stereo, or mid-side modes
For the first time, process your audio with the rich, brilliant sound of the Black Box using mid-side processing for more sophisticated control over your sound. Saturate the sides, while keeping the center clean and punchy, or use more edgy odd-order saturation on the side and warmer even-order saturation on the center—or vice versa.

Paint Your Tracks with a Whole Palette of Tube Colors
HG-2 emulates four different vacuum tube stages combined in series and parallel circuits to color your mix and individual tracks with a wide range of rich and varied harmonics. Separate gain controls for emulated 6U8A pentode and triode tubes are placed in series between buttery virtual transformers warming the plugin’s input and output.

Dial-in the perfect blend of pentode and triode tube sweetness
...then adjust the Density control to drive both tubes harder without changing their relative balance or the plugin’s output level, adding more girth and mass. The Calibration menu emulates the effect of an internal trim adjustment in the original hardware unit, instantly modifying the HG-2’s high-frequency response to produce Dark, Normal, or Bright coloration.

Sprinkle, punch und tube softness
An added Air knob lets you control how much high-frequency fairy dust you sprinkle on vocal tracks, string instruments, piano, and full mixes. Turning down the Mix control adds back dry signal at the plugin’s output, combining HG-2’s beautiful tube softness and luster with your mix’s perfectly preserved detail and punch.

    I love that you can really dig into the different parameters of width and tone to achieve pretty much anything your creativity desires.

    I like how subtle but present the Black Box MS is, I love the extra grit, warmth, and saturation you can achieve and I've been trying it on different instruments and on the mix bus.

    I love the new M/S function! You can add subtle width to a mix or source without it becoming a phase issue or collapse issue when summing to mono. Very nice!
