The API 2500 is a versatile dynamics processor that lets you shape the punch and tone of mixes with absolute accuracy. Its dual channel design lets the 2500 also function as two separate mono channels via a single compression setting. Using auto-makeup gain, you can adjust Threshold or Ratio while automatically maintaining a constant output level. With both “feed back” and “feed forward” compression types, the API 2500 boasts a wide range of incredibly musical parameters which have made it a favorite of engineers the world over. Developed in association with API, the API 2500 modeled vintage compressor plugin includes a switchable 3-position Thrust high-pass filter, variable link left and right channels, 3 Variable link filter types, 3 Compression modes: soft, medium and hard knee, and 6 Release settings: 5 fixed, 1 continuous.
