Complete Channel Strip Plug-in

Bigger is Better

Originally designed for integrated compatibility between Studio One and StudioLive mixers, Fat Channel XT brings award-winning StudioLive processors and State Space models of vintage EQs and compressors to your DAW of choice.

Fat Channel XT was designed to be the ultimate channel strip for any input or bus with a variable high pass filter, gate/expander, compressor, EQ, and limiter—all in one singular plug-in. In addition to the classic StudioLive compressor and EQ modules, you get two State Space Modeled compressors and EQs recreated from coveted vintage studio gear.

Need more virtual analogue goodness? Fat Channel XT can be expanded with any or all of the eight compressors and seven EQ models in the Fat Channel Plug-in Collection.

The Channel that Built a Million Mixes

From the moment the original StudioLive shipped over a decade ago, the Fat Channel was an instant hit. With a fully variable high pass filter, a noise gate designed to never click, a musical compressor based on PreSonus’ famed ACP88, a four-band parametric EQ and a Limiter to round it all out, the Fat Channel gave StudioLive users all the tools they needed to craft the perfect mix.

As StudioLive mixers evolved, so too did the Fat Channel; and Fat Channel XT was born to provide a fully integrated experience for StudioLive Series III users inside Studio One. Now that same Fat Channel XT plug-in is available in VST3, AU, and AAX formats for nearly universal compatibility with 3rd party plug-in hosts.

The Fatter Channel

PreSonus developers stand at the forefront of State Space Modeling technology, and they put their expertise to good use when designing the latest-gen Fat Channel XT by adding hybrid State Space models of vintage compressors and EQs. After installation, you’ll find three compressor models complete with Key Listen functions, plus three EQ models inside Fat Channel XT.

The compressor and EQ order can be reversed, allowing for precision sculpting of your sound. Each processor can be disabled or enabled individually and if you need more virtual vintage goodies, PreSonus offers eight additional compressor models and seven additional EQ models as add-ons.

Compressor offers the following choices:

  • Standard: A flexible, modern compressor, with a clean, hi-fi sound.
  • Tube: A model of one of the best-loved vintage tube-based opto-compressors. Excels at vocal smoothing and at making bass instruments sound larger-than-life.
  • FET: A model of one of the most-used vintage FET-based compressors. Great for adding an aggressive edge and accentuating room sound for drums, guitars, and other highly transient signals.

Equalizer offers the following choices:

  • Standard: A flexible, full-featured modern EQ, with a clean, hi-fi sound.
  • Passive: A model of one of the most sought-after vintage tube-based passive EQs. Deceptively simple controls and a rich, thick sound make it perfect for gentle tone-shaping or adding vintage character.
  • Vintage: A model of what some call the “final word” in vintage solid-state EQs. Combines an “everything sounds better through it” quality with musically chosen EQ frequencies for quick, reliable tonal magic.

State of the Art

The vintage compressors and EQ in Fat Channel XT are meticulously recreated from the original analogue circuits using State Space Modeling technology. This same technology also powers the Ampire amp models, Channel Strip Collection plug-ins, and the Studio One Console Shaper, ensuring that the nuanced, variable sonic character of analogue survives its transition to the digital realm.

State-Space Modeling isn’t just about sampling vintage compressors and EQs and getting some sounds within the sonic ballpark, no—State Space Modeling is the surgical measuring and re-creation of old hardware on the per-component level. Each capacitor, every resistor, all the diodes and every nonlinear circuitry element of the complete hardware schematics have their behaviour measured, modelled, and re-created... including even component-specific non-linearities.

The result? Wonderfully perfect virtual models of wonderfully imperfect audio hardware. No transformer unturned, no valve left behind.
