2500+ Stereo Bus Compressor

The API 2500+ is the latest iteration of the legendary stereo bus compressor that has been a staple on the mix bus of top engineers and producers for years. This 1U rackmount unit delivers the unparalleled punch, glue, and analog character that can only come from an API compressor, making it an indispensable tool for adding cohesion, weight, and energy to stereo mixes, drum sub-groups, and other stereo sources. The 2500+ builds upon the success of its predecessor with an expanded feature set that offers even more flexibility and control, solidifying its status as an industry-standard dynamic processor.

The 2500+ retains all the classic features that made the original a favorite. At its heart is API's patented "Thrust" circuit, a unique filter placed before the detector that preserves the punch and power of the low end while adding a tight, aggressive character. The unit can be operated in either "Old" mode (feedback compression, like the vintage API 525) or "New" mode (feed-forward compression, like modern VCAs), providing two distinct sonic personalities. The new version adds an expanded ratio range, a "Mix/Blend" control for easy parallel compression, and a refined "Thrust" detector with three selectable modes for even more precise tonal shaping. With comprehensive controls for Threshold, Attack, Release, and Ratio, plus selectable knee shapes and a variable link function, the 2500+ is a supremely powerful and versatile dynamics tool for any serious studio.
