An obsessively accurate emulation of API’s flagship compressor.

The API 2500 Bus Compressor is a permanent fixture on the stereo bus of many of the world's top engineers and producers. Considered the best of the Paul Wolff-era API circuit designs, this famed compressor adds energy, movement, and tone to stereo mixes and subgroups unlike any other compressor.

The API 2500 Bus Compressor plug-in for UAD-2 hardware and Apollo interfaces is a spot-on emulation of this classic compressor, capturing its all-discrete signal path with Thrust® circuitry — and features a fanatically detailed modeling of API's custom transformers and 2510 and 2520 op amps.

Now You Can:

Glue together your stereo mixes and subgroups with the world’s finest circuit emulation of the iconic API 2500 compressor

Select between "Old” and "New” compression, with feedback or feed-forward sounds

Sharpen your workflow with plug‑in‑only Mix and Headroom controls

Punch up low frequencies with API's patented Thrust technology

Contour your mix's stereo interaction with percent-based L/R Link controls

Mix with artist presets from Jeff Balding (Faith Hill), Vance Powell (Jack White), Ryan Hewitt (Red Hot Chili Peppers), and more

The Only End-to-End API 2500 Emulation

The Only End-to-End API 2500 Emulation

Poring over proprietary "for-your-eyes-only" schematics made available to Universal Audio by API, our team of DSP experts analyzed two classic API 2500s — rackmount and in-console — ensuring one of UA's tightest behavioral circuit models to date. Working together with API's engineers, we scrutinized every facet of the plug-in against its analog counterpart, delivering the definitive representation of this iconic compressor. Early beta testing with UA artists confirmed that the plug-in ranks among the most accurate analog emulations in UA history.

Built for the 2-Bus

Built for the 2-Bus

API designed the 2500 compressor with program material firmly in mind. Its Release control includes fixed or variable options, while the Attack, Threshold, and Ratio controls offer musical tweaking throughout their range, making the API 2500 a toneful dynamics overlord for your stereo bus.

Shaping Tone and Dynamics

Shaping Tone and Dynamics

The API 2500 allows selection between three custom-voiced compression Knees — Soft, Medium, and Hard. You can shape the tone further with two compression types; "Old" for characterful peak-detection harkening back to API's earliest, highly-coveted 525, or "New", which features a modern feed-forward design.

Thrust Control for Unmatched Punch

Thrust Control for Unmatched Punch

Taken from their Paragon series of consoles, the API 2500’s Thrust feature puts a filter before the RMS detector, evening high and low frequency energy — so neither triggers the compressor more than the other. This gives you a tight hallmark API punch beyond any other compressor.

Enhance Energy and Motion

Enhance Energy and Motion

Most compressors only allow you to turn left/right linking on or off. The API 2500 Bus Compressor Link parameters allow for precision control of your mix's L/R dynamic interaction. Set exactly how much dependence — or independence — you want your L/R spatial dynamics field to have, and hone your dynamic contours even further with the Shape control.

Learning Curve But Worth It

I gave this four stars... and that is kind of unfair. The truth is this unit requires some study and trial and error. But once you have it dialed in, it makes the drums sound incredible. I like it on the electric guitar bus as well. Killer.

Tight bottom end for electronic music

I write electronic music, in particular trance, so I was looking for a bus compressor to tighten up my low end and keep the whole mix clean & together. I've been using the Shadow Hills for the last 3 years, but it never write hit the mark, and so, in the tradition of the never ending search to improve my production, I demoed the API, Zener, elysia & the SSL G (2017 version) For me the API was the most consistent in levels, whilst adding some dirt to the low mids, the SSL was a close 2nd, however I found that it was too varied in it's gain reduction when the bottom end was absent. I also use this daily for my Post production mixes - it's so flexible with the selectable knee, the old & new styles and the thrust component.....definitely add this to your demo list. I'm very happy with this one :)

By far the best digital version of the API 2500

I have been a close friend of Paul Wolff since working at The Bayou in Georgetown D.C. in 1978 where he was the house engineer. I became the second FOH guy shortly thereafter.

He built custom devices in the FOH console including the Flanger/Doubler that Softube is doing a digital version of these days (UA..please add this to your product list soon.)

I bought a prototype 2500 from Paul right after he made one for a few old friends of his. It was a magic box for me. I stopped using the SSL Buss Comp on the 8000GB console I worked on daily once I bought my 2500.

The 2500 prototypes (maybe 12 were made) and the following production versions are wonderful pieces of hardware. I never found a digital version that came close until the UA version. If UA were to ask Paul about the changes between the proto and the production versions, it would be a great update to add onto the 2500. If not, the existing 2500 is a steal just as it is.

Excellent plugin!

Having used the Waves version for some time I took the plunge and went UAD's version or should I say update, as UAD's API 2500 is definitely the Rolls Royce of the two. Exceptional buss compression that can also be used on tracks and also comes with some great presets.

Wonderful

Even though I already had the Waves and Liquid Mix versions (the latter is excellent), I decided to demo the UAD version. At light settings, it didn't seem much different than the others. When I began to push it, my jaw hit the floor. Some real magic in this plug. Never thought I'd bother to purchase yet another comp, but it was just too compelling not to.

Picante!

Agresivo, pero tambien puede ser sutil. Gran posibilidad de extremos y colores. Un jugador de toda la cancha!

A step up

I also have the Waves version of the 2500 which I always liked for the drum bus and sometimes on the mix bus. The UAD is definitely a step up, and now I'm addicted to it on the mix bus. I really like using the wet/dry mix knob and headroom options that they added. Another fine emulation from UA, and it's quickly become an essential part of my mixing process.

Правильный выбор для компрессии шины

Просмотрел много обзоров, поработал с демо-версией-купил и не жалею-отлично звучит-хорошо склеивает группы инструментов и на мастер-шине на своем месте.

Solid as a Rock

The API 2500 Bus Compressor clearly brings out the best in a signal. This plugin not only works beautifully on busses it really shines on single sources as well. I am using it from vocals to bass and drums. The sound is always solid as a rock with a nice and tight low end. There is no smearing but clear definition even under heavy compression. Great work UA!

Using it like a maniac

This compressor is so satisfying. I'm enjoying the presets and getting to know my way around the features. I'm using it on everything and it sounds great.

Excellent.
Almost like the UA hardware version has done a great job.
