Description
Enter a world where your mixes come alive with the iconic punch and energy of the API 2500, now available as a plugin from Universal Audio. The UAD API 2500 Bus Compressor takes the legendary capabilities of the hardware compressor and fuses it with cutting-edge digital technology, offering a perfect blend of analog warmth and digital precision. Developed in close collaboration with API’s engineers, this plugin ensures that every detail of the original circuitry is meticulously emulated, down to the custom API transformers and op amps.
Whether you're looking to add a subtle sheen to your stereo bus or to aggressively shape subgroups, the UAD API 2500 delivers with its two distinct compressor types and three custom-voiced compression Knees.

The Dry/Wet Mix knob facilitates quick parallel processing, while Headroom controls offer user-defined operating levels for tailored compression.

Used on the guitar in "Sparkle Mountain", as described in the project breakdown at 1:59.
Mariah Carey is confirmed to use the UAD API 2500 Bus Compressor during her "The Butterfly" residency in Las Vegas. This information comes from her mixing engineer, who highlighted the use of various UAD plug-ins to perfect the show's sound. He specifically mentioned, "For instance, getting the snare right was crucial—a factor that sent Strong on a quest, working through a string of plug-ins until he settled on the API 2500 Bus Compressor: 'That was exactly what I was looking for. It helped me control the snare on the hard hits and keep the rim shots right where I needed them—there’s a significant amount of rim-shotting in the show, because, you know, R&B ballads.'" This was reported by Clive Young in a Mixonline article titled "Mixing Mariah at the Colosseum: Live Sound Showcase."
