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.

      API 2500 Bus Compressor

      My Favorite Drum Mix Bus Compressor. It' so versatile. I actually use it in different way, I don't just set it on the Master Mix bus and leave it. Thou, I do do that too. This is a fun Compressor to get to know. I wish I 'd had purchased it sooner. I have a tip....Just buy 'em all. You will eventually! The Best! UAD has the Best! - Gilroy

      Exactly what I was looking for...

      I have never used the original but, as soon as I started using this plugin on my drums...I found the sound I was looking for. Solid compressor, my go to for drums and basses.

      Best API 2500 Emulation on the market

      Closest emulation to the original API 2500 didn't believe it until I got it.

      Creates great space

      I find that its great to carve out space, especially on the mix bus of drums and backing vocals. Great definition in it.

      Even with APIs, even strong, powerful sounds!

      Simply changing the value makes it easier
      old is especially recommended

      I use it as a bus compressor on a lot of my Drum and Mix Busses. It is a wonderful tool.

      API 2500 Beast

      It's a secret weapon for a lot of Punch. The Type New and Old is a great tool to choose what you want. One of my Favorites

      any earlier attempt I've heard of the API2500 fades. Seeks and destroys the waves version. Only wish is that the rather heavy DSP load would magically disappear, but I guess it explains why it sounds so good!

      This really rocks!

      By far the best API 2500 emulation.

      Really really good!

      I love how this compressor adds some punch to my mixes. I've tried other compressors on the buss mix and some can achieve what I hear in my head, but the API 2500 is the only buss compressor that consistently meets or exceeds my expectations. It's the one I will go to first, due to its intangible ability to read my mind (or plays what I want to hear).

      On a scale of 1 to 10, it's a 2500

      I was always very happy with another mix compressor I've used for years. Then I tried this, and it felt like I was leaving the Stone Age and entering the period of Enlightenment. I love aggressive-yet-musical compressors, and along with the Fairchild 670 this is the best UA plug in for that colour I've ever heard. Bravo!
