Brainworx bx_digital V2 EQ Plug-In
developed by Brainworx

One of the World's Finest Audio Mastering Tools, Now Available on the UAD-2 Platform.

The bx_digital V2 is a state-of-the-art digital mastering equalizer and processor that was recently named Future Music's "Gear of the Decade." This integrated audio toolkit provides precise 11-band equalization and M/S (mid-side) processing of single tracks, subgroups, or summed signals — letting you add presence and transparency to mixes, create impressive lows, correct problems, and emphasize the character of individual instruments and entire mixes. With its independent mono and stereo processing paths, plus an array of intelligent features, the bx_digital V2 has quickly become a must-have tool for many of the world's top mixing, mastering, and post-production engineers.


  • Intelligent mastering processor with 3 Modes: M/S mastering, M/S recording, L/R stereo
  • Process Mono and Stereo signals separately, with precise control of each signal
  • Powerful and unique "SixPack" Master Section
  • 11-band EQ, including Shifting EQs up to 22 kHz
  • Built-in M/S De-Esser / Dynamic EQ (20 Hz – 22 kHz)
  • Package includes UAD bx_digital V2 mono version for mix applications
  • Developed for the UAD Powered Plug-Ins platform by Brainworx
  • Requires a UAD-2 DSP Accelerator Card or Apollo Interface available from authorized dealers worldwide
  • View All Features

Brainworx's bx_digital V2 plug-in was developed directly for the UAD platform by Brainworx to emulate their bx1 and bx2 hardware mastering units. Like the hardware, the bx_digital V2 plug-in works in any of three modes: as a stereo/dual-mono EQ; as a M/S matrix equalizer for applying level and EQ changes separately to mid- and side signals; and as a M/S recording processor for converting mid and side mic signals into conventional stereo. The bx_digital V2 plug-in package also includes a bx_digital V2 mono version, perfect for mix equalization of sources like vocals, kick drum, and other typically mono signals.

With its mastering-grade 11-band equalizer, M/S De-Esser, Mono-Maker and intelligent Bass- and Presence-Shifters, plus its extra M/S features — including individual Pan controls for M and S, and Stereo Width Control — the bx_digital V2 is a very sophisticated processor. But fundamentally, its operation is extremely logical.

Put simply, the bx_digital V2 processor works via a built-in M/S matrix, that separates every stereo signal into its mono sum and the stereo difference signals. In this way, users can separately control the mono and stereo elements like never before. For example, users can simultaneously cut high frequencies of a mix to reduce the "essing" of the lead vocals, while boosting high frequencies of harmony instruments, like guitars, keyboards, and pianos. Or effortlessly separate low-level signals to enhance the clarity and punch of a mix. The bx_digital V2 mono version shares the features and great-sounding filters of its stereo counterpart, and is ideal for mixing use.

Shifting EQs
The bx_digital V2's "Shifting" EQ section has four processors: Presence Shift, Bass Shift, De-Esser, and Mono-Maker.

Presence Shift boosts at 12 kHz and simultaneously cuts at 6 kHz. It has a range of ±12 dB and puts "air" into the sound without exacerbating sibilance.

Bass Shift boosts at 63 Hz and simultaneously cuts at 315 Hz. With a range of ±12 dB, Bass Shift can fatten the bottom end or push the low midrange without booming out the low bass.

De-Esser is a 2-channel dynamic equalizer with an adjustable frequency range of 20 Hz to 22 kHz, and an adjustable threshold range from 0 to –60 dB.

Mono-Maker forces all frequencies from stereo to mono, and is adjustable from 20 Hz to 22 kHz — perfect for tightening up the low-end in any mix. (The Mono-Maker is typically set between 60 - 100 Hz.)

In Use
Applications for the bx_digital V2 plug-in include recording, mixing, mastering, post-production sweetening, sound design, and audio restoration.

    Never a master without it
    by P. Milani(Thursday 11 June, 2015)

    Loved it at first 'sight'. I'm not a proper mastering eng but since I tried out this plugin all my masters seem magically easy to do. Sounds very musical at light to moderate settings. Works wonders for critical fixes at extreme settings and more often than not it saves the day. Read More

    A whole new dimension
    by J. Rostrup(Tuesday 9 June, 2015)

    The best way to discribe this plugin is how flat and dull the mix becomes when you remove the plug. It's like when you shut off the sub on your PA. You don't know it was there till it's gone. Read More

    Metal guitar diamond cutter
    by N. Dranov(Friday 22 May, 2015)

    My band and I just finished our home-produced 10 track post-death/metal album. And believe me, for mixing higain metal guitars the bxv2 was a true lifesaver. With Slipperman's eq guide in hand we used the v2 almost solely for subtracting (we chose to boost with trident/pultec) all the fizzy… Read More
