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.

    Would Purchase If I wasn't already happy with other eqs
    by T. Urban(Monday 30 November, 2015)

    I love working with this eq. However, for my few small mastering sessions, I usually use Ozone. Larger sessions with a budget, I will send out to a proper mastering house. This is exactly the same as the native version. See my tutorial below: I do… Read More

    Amazing mastering EQ, stereo enhancer & mono maker
    by J. Barriuso(Monday 19 October, 2015)

    I´ve been using V2 for a couple of weeks and I am impresed with it´s work in the master chain. It´s not the good quality of the eq (I add also Maag for a bit of colour and air), but this thing gives you a lot of possibilities an usual EQ doesn´t. With M/S you have a totally different… Read More
