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.

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.

      Awesome !

      need to try and learn, so much character but not for beginners. never love the SSL G-Bus Glue, cause API 2500 is much easier and punchier!

      One of the Best 2 Bus!

      This plugin sounds so good on a drums!
      Then I tried it on my guitar, bass and vocal busses! Wheeeew! It gave it a nice glue and gelled the mixes together as a record! Don’t pass up this one!

      Color Api

      Me encanta por ser un compresor con un carácter bastante transparente aunque te suma un pequeño plus análogo que es muy dulce de escuchar.

      Good, but no sidechain support when using with UAD-2

      It's just a shame the UAD-2 version for Apollo does not support sidechain, only the native seems to have this, otherwise good compressor.

      Good Bus Comp

      It's a good bus compressor. Plenty of room for makeup gain. The shape control is also very nice and effective.

      The Drum Buss Must

      The API2500 is the compressor for the drum buss, keep the punch and glues every hit with a nice color of the circuit. In Parallel is a beast also.
