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.

Deep and beautiful

Great piece of kit. It has a learning curve as there are a lot of controls, but it's all very meaningful. Sounds stunning.

Drum Bus dream come true.

Using this across the drum bus tightens everything and adds a fatness that wouldn't translate other wise. Sometimes, I use a very hard settling on it and drive the input so that it almost clips, giving it a overdriven sound which can be fun. I wouldn't say this compressor is transparent so I'm not sure I would use it on the stereo bus but it's perfect over my drums, couldn't be happier.

Best ever

Best software bus compressor ever.

Delicious sound

Over the past few years another version of this plugin became my goto compressor for multiple uses. I dreamt of the day UA would release this plugin and I am so incredibly happy with the results. This is at the top of my desert island list now. Thanks UA!

UAD plugs are more and more like the real thing....

Man. I honestly don't know that I've used a plug-in yet where I just thought "well, I just don't need the real thing now, at all" but this one feels exactly like that. There have been plenty that I've been very happy with of course. I love the Manley vari-mu plug, but I still bought a vari-mu to put at the end of my mix chain recently. But........ the API 2500 plug just truly, really, completely responds like the real thing. I've used in on mixes and it really brought them to another level. Drums, electric guitar, even used it on a vocal recently that just needed something different and it was perfect. This has really upped the ante, to me.

Silky smooth compression

Very enjoyable compression on the old ears. Transparent on the mix bus and can smash the hell out of drums. Seriously consider getting this over anything else.

Amazing Flexible Mastering Comp

I just got this and tried it on the Master Bus for a new Drum and Bass track as well as Dreampop electronica track.. The glue presets just work right away on any style of music.

I was blown away how flexible this is for song styles yet still work the same magic on it

The Mix knob just makes parallel compression super easy as well.

I love this thing

My new secret weapon ;-)

This thing is money in the bank and it is my new secret weapon. Warm, rich analog sound at its finest. Totally love it!

Incredible

This plugin works great on just about any kind of mix! A great addition to my UA collection!

Very Close To The Real Thing

I've got the 2500 hardware comp, and it sounds amazing, but I honestly haven't touched it since I got my UA rig. The software is so freakin' close at a fraction of the cost, and you get recall, automation, and multiple instances.

I haven't been able to bring myself to sell my hardware unit yet, but at some point I'll get tired of seeing it sit idol in my rack.

Quality and Rock and Roll!

It sounds too warm. I don't wanna to make any comparation... but sometimes you have to. It's sounds so analog and so beautiful that makes other emultations be ashamed. Great work guys!

2 Bus comp!

I use the SSL 2bus comp + API 2500 on my mixbus, with excellent result!

Excellent all-around compressor

The compressor has a nice smooth character and it can make drums pop in great way. Due to its heavy coloration the mix knob is an wonderful addition and makes the compressor highly usable in the master bus. Guitars, vocals, synths, drums, bass, it basicly works with everything if you just like the character of the compression. Highly recommended.

Excellent for drums and bass!

When Waves plugins were my primary source of software, I avoided the API compressors after a very unsuccessful demo of the products. After trialling the UAD version, I took an immediate decision to purchase this and the 500 series EQs, as I knew I would be using them regularly on sessions.

Plug-in quality is getting better and better.

The compression quality is very good.
What the music looks like after it won't lose anything can achieve good results
Be sure to buy this plugin

Feels like an analog comp

I'll admit it - I'm not a great mixer. Back in my tape and board days, I used to rent a real SSL Bus Compressor that magically evened everything out (both levels and tones). I've tried almost every compressor plugin made. This one finally brings me back to those days. Thanks UA!

Blows the Waves API 2500 away!

This is such a great compressor. Nothing punches quite like it. The UAD API 2500 comes so much closer to the hardware unit than the Waves version. Still, I think both come a pinch short of the smack you can get out of the hardware. Despite this, the UAD API 2500 sounds stunning and I will be using it on every mix.
