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.

      Meaty!!!

      I put this on my percussion bus and the section just sing! You can hear the effect of the compression in action, but that's not a bad thing in the case of this plugin as the compression is incredibly musical. I'm lucky enough to have used a real API 2500 Bus Compressor and this plugin sounds just like it. Brilliant!

      Produces expected results, which is a good thing!

      Can be a little "thick" in the low mids like the hardware so you need to be careful if your mixes often suffer from low-mid build up, but overall it's very good and probably the best emulation out there. The only thing more 2500 than this is the actual hardware. I like the fact UA have now started including functions that aren't on the hardware too like mix controls etc.

      Wow, great & flexible compressor.

      I have many of the UA compressors. I love this for a simple and flexible compressor with a bit of vibe.

      Works great on almost anything: vocals, bass, busses…

      It works really well as the integrated extension in Luna - nice to be able to dial it in just in the mix window and use native processing rather than the UA DSP resources.

      Its variable compression ratio and switchable options really allow a lot of compression choices from one unit, but it also adds a bit of clean, warm vibe.

      Been waiting to pull the trigger on this for a while...

      Just use it mainly for the mix glue and bus glue as intended and works a charm. spot on.

      real

      I also own a version of waves, but I feel that UAD is closer to the real thing. Both are wonderful.

      Compression with character.

      I have worked with this compressor in real life but never owned one personally. I’ve had emulations before that didn’t get it right until now. UA nailed it.

      The best way to refine a mix

      very efficient on drums and mix buss; rich of harmonics and super versatile on everything needs more punch
