Universal Audio API 2500 Bus Compressor – Dynamics Plugin (VST/AU/AAX / UAD or Native) Universal Audio

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 Ñ and features a fanatically detailed modeling of API’s custom transformers and 2510 and 2520 op amps.

Features:

• Glue together your stereo mixes and subgroups with the worldÕs finest circuit emulation of the iconic API 2500 compressor
• Select between “OldÓ and “NewÓ 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
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 Ñ rackmount and in-console Ñ 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
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
The API 2500 allows selection between three custom-voiced compression Knees Ñ 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
Taken from their Paragon series of consoles, the API 2500Õs Thrust feature puts a filter before the RMS detector, evening high and low frequency energy Ñ 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
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 Ñ or independence Ñ you want your L/R spatial dynamics field to have, and hone your dynamic contours even further with the Shape control.
