Dangerous BAX EQ Collection
developed by Brainworx

Sweeten your Mixes with One of the Smoothest EQs Around.

The Dangerous BAX EQ Plug-In Collection is a powerful tool for shaping and enhancing the tonality and character of your music. Designed as a “finishing EQ,” the BAX EQ Collection is the first and only authentic plug-in emulation of this studio staple, available exclusively for UAD-2 and Apollo hardware.

Now You Can:

  1. Apply sweet, musical EQ tweaks based on Peter Baxandall's legendary 1950s EQ circuitry
  2. Rid your mix of unwanted subsonic frequencies, cleaning up the low-end and increasing your headroom
  3. Tame high-end harshness while simultaneously opening up your mixes with air and transparency
  4. Enhance stereo imagery and depth with Mid/Side function on stereo “Master” version


BAX History

The inspiration behind the Dangerous BAX EQ is Peter Baxandall's legendary 1950s EQ — a tone control that graced thousands of hi-fi systems. Baxandall’s simple, gloriously effective EQ sweetened up program material by simultaneously employing broad, open curves and gently sloping cuts. Designed in partnership with Brainworx, and Dangerous Music Digital, the Dangerous BAX EQ Collection is a circuit-accurate emulation of the original analog hardware for UAD-2 DSP Accelerators and Apollo-equipped workstations.

The BAX EQ Collection contains two independent plug-ins: the Dangerous BAX EQ Mix and the Dangerous BAX EQ Master — a stereo version with Mid/Side processing capabilities.  


Clean-Up Your Low-End

The Low Frequency Filter Control dials-out offending low-end junk that can pile up in your mix, from infrasonic rumble caused by air conditioning units and other environmental sources. This control will not only make your tracks more focused sounding, it will also afford you more headroom for punchier mixes. Accurate and musical, the Low Frequency Filter also works in conjunction with the Shelf functions to skillfully sculpt curves and tighten your mix’s low-end without changing the character of the bass response or the mix.

Add Air and Sheen, Lose Harshness

Tame undesirable transients in a mix without losing aggressiveness or bite, or add a silky shimmer to vocals with the BAX EQ plug-ins’ High Frequency Filter. It can even tame ultra-high frequencies that can rob your mix of clarity and musicality. In tandem with the Shelf controls, the High Frequency Filter can transform the all-important top-end of your mix into something glorious.

Subtle, yet Powerful Tone Shaping

With its broad bandwidth shelving, the BAX EQ Collection provides you with a subtle, yet powerful control of the frequency spectrum. The minimized phase delay design provides extensive tonal control that will not alter the intrinsic sonic character of your source — even at extreme settings. The BAX EQ plug-ins will make your tracks richer and sweeter, while keeping all of their sonic signatures intact.




What makes the filters of the BAX different from other EQs?
Other filters leave a sonic signature residue - the BAX is extremely phase coherent and will not alter the character of the music.

What overall benefit do the BAX filters provide for my full mix?
Whether used cumulatively on multiple tracks when mixing, or when used in mastering applications, the BAX low frequency controls dramatically increase low end clarity and punch while allowing higher maximum levels on any playback device. The BAX high frequency controls reduce harshness, taking the burden off of digital audio converters allowing them to reproduce a tighter, more accurate representation of the source.

Is the BAX EQ also beneficial for tracking?
Yes, leverage the BAX EQ for tracking. Even in “cut only mode”, utilize it on every track to control the source’s frequency range, thus dramatically focusing the energy and making the mix process a snap.

What sources do I use the BAX Mix plug-in with?
Any mono, stereo, or multi-mono source.

What sources do I use the BAX Master plug-in with?
Any stereo source.

What is different between the two plug-ins?
Dangerous BAX Mix features one set of controls, applying filter settings evenly across all input channels at all times. The BAX Master plug-in provides additional controls useful for stereo mastering applications or whenever it is desirable to have independent control of the left/right or mid/side signals - Dual-mono controls, a switch for the linking/de-linking of controls, and a switch to engage M/S (mid/side) mode.

In addition to tone control, the BAX EQ is useful for filtering out of band noise (infrasonic lows and ultrasonic highs), why should I care about signal outside of the audible band?
While the target frequencies of the BAX cut filters may be outside the audible band, filtering infrasonic and ultrasonic frequencies can result in a definite increase in clarity for the audible band. Infrasonic lows are commonly picked up in the recording process, robbing your signal chain of available headroom and resulting in a muddy indistinct low end. Ultrasonic highs are the nemesis of digital audio convertors and are ultimately the cause of the "brittle" sound of many digital recordings. The BAX EQ helps eliminate both of these common problems quickly and easily, allowing for increased total loudness and improving the effectiveness of additional dynamics processing, all while leaving the tonality of the source material intact.

So using both the cut filters and the shelf filters simultaneously can yield pleasing results?
Yes, absolutely.

    The Dangerous BAX EQ is my new favorite box to put across my whole mix. It lets me achieve that modern pop brightness without any of the usual sibilance or harshness. The super low-end is fat without being muddy.

    Dave Kutch

    (Justin Timberlake, Talib Kweli, The Roots)

    “I want the Dangerous BAX EQ for the 84 Hz band alone. While test-driving the prototype I got addicted to it. It gives me a ‘foot’ like no other EQ I have does.”

    John Paterno

    (Robbie Williams, Badly Drawn Boy, Bonnie Raitt)

    “As an avid user of the hardware, I was stoked to see the new UAD BAX EQ Collection. After using the BAX EQ Master plug-in with the M/S option, I have only one word — Awesome.”

    Phil Demetro

    (Paul Anka, Our Lady Peace, Enter the Haggis)

    “The Dangerous BAX EQ is unlike anything you have heard, but exactly like what you’ve been looking for.”
