The Expandable Fat Channel

The Fat Channel XT plug-in was built to grow. Just like the vintage tube compressor and passive EQ models included in Fat Channel XT, Fat Channel XT Add-ons are State Space Modeled by world-class engineers with Ph.D.'s in the digitizing of analog circuits to faithfully produce the sound and response of the original hardware processors. Even better, the unique hybrid format of Fat Channel XT Add-ons is designed to work both in the Fat Channel XT plug-in and in StudioLive® Series III mixers. So whether you’re mixing in your favorite DAW or on your StudioLive digital mixer, you can take the same vintage processing goodness with you.

Compressors

Our eight classic compressors cover the gamut, including FET, tube, optical, and VCA designs. From soft, smooth attacks to fast, in-your-face response, you’ll find it in the Fat Channel Collection.

RC-500 Compressor

FET-based compressors such as the one in the PreSonus RC 500 use transistors to emulate a triode tube’s operation and sound. This type of compressor generally provides a faster attack time and better repeatability than the optical compressors typically found in channel strips. Modeled after PreSonus' signature RC 500 FET compressor, this plug-in provides an ultra-fast attack time and repeatable performance.

Included in the free PreSonus Bundle.

VT-1 Compressor

Stunning high-end sound and incredible versatility are hallmarks of PreSonus’ VT-1, which is modeled after a popular vacuum tube channel strip’s FET compressor. The VT-1 provides fast attack and repeatable performance with a fully variable ratio.

Included in the free PreSonus Bundle.

Brit Comp

Capturing the unique sound of a twin VCA gain-reduction amplifier design, the Brit Comp is ideal for taming piano dynamics or adding punch to drums and percussion.

Included in the Classic Studio Bundle.

FC-670 Compressor

This model of an iconic compressor/limiter of the 1950s imparts an unmistakable silky warmth on just about any signal.

Included in the Classic Studio Bundle.

Comp 160 Compressor

With simple controls, yet capable of extreme compression traits, the Comp 160 provides VCA character with a personality all its own. Try it on drums; you’ll be glad you did!

Included in the Modern Classics Bundle.

Everest C100A Compressor

Based on a classic design focused on gentle, natural-sounding gain reduction, the Everest C100A helps control dynamics while still letting the signal breathe.

Included in the Modern Classics Bundle.

Classic Compressor

The smooth character of this compressor allows you to create transparent or extreme color changes to your audio, making it a workhorse for just about any application.

Included in the Vintage Channel Strips Bundle.

Tube CB Compressor

In general, the response time of optical compressors tends to soften the attack and release, which can smooth out uneven volume fluctuations. Emulating an all-tube, optical design, the Tube CB compressor delivers musicality, preserving the clarity of the signal even at the most extreme settings.

Included in the Vintage Channel Strips Bundle.

Equalizers

Each of these seven popular equalizers offers a different flavor, from the classic British sound of the Solar 69 to the subtle Baxandall; the smooth, refined VT-1 tube EQ; and the more modern, solid-state RC 500. As with all processors in the Fat Channel Collection, they’re state-space modeled so they respond just like the original hardware circuits.

RC 500 EQ

It's rare to find a truly outstanding solid-state channel strip that can deliver a vintage vibe reminiscent of classic high-end products, yet employs a thoroughly modern design. The PreSonus RC 500 was one of these rare gems. The RC 500 EQ plug-in is modeled after the channel strip’s three-band semi-parametric EQ and combines isolated filters and optimized, per-band Q to provide subtle signal-shaping without harsh artifacts.

Included in the free PreSonus Bundle.

VT-1 EQ

The VT-1 EQ models a popular vacuum tube channel strip’s four-band semi-parametric EQ, which combines isolated filters and optimized, per-band Q. Designed with musicality in mind, this EQ is smooth and refined, which made it an instant classic.

Included in the free PreSonus Bundle.

Alpine EQ-550

The 1960s-vintage EQ provides consistent, repeatable equalization using three overlapping bands, divided into seven fixed frequency points, each with five steps of boost or cut. Its selectable peaking or shelving filters for the high and low band, along with an independently insertable bandpass filter, provide an easy path to creating acoustically superior equalization.

Included in the Classic Studio Bundle.

Solar 69 EQ

The sound of classic British EQ is absolutely legendary and has enhanced many a great recording. Emulating this classic British design, the Solar 69 EQ adds definition to kick drums, shapes electric guitars, and adds shimmer to acoustic guitars and vocals without sacrificing body.

Included in the Classic Studio Bundle.

Baxandall EQ

This EQ offers the world's most popular EQ curve. Using gently sweeping treble and bass EQ shelves, it allows you to make subtle, yet effective, changes over wide swaths of the frequency spectrum.

Included in the Modern Classics Bundle.

Tube EQ

This midrange EQ is based on a passive, all-tube design for ultra-smooth and musical equalization, making it ideal for any midrange source material.

Included in the Vintage Channel Strips Bundle.

Vintage 3-band EQ

With its distinct filter shaping, sheen, and bite, this three-band active EQ includes both high and low shelving filters, providing enhanced tone-shaping possibilities.
