API 529

The 529 stereo compressor from API takes the brand's praised 2500 stereo bus compressor as a point of inspiration, and repackages it into a modern travel-friendly 500-series format module. Faithful to the brand's impeccable sonic aesthetic, the 529 offers a plethora of features that make it an excellent choice for a variety of applications without sacrificing the clarity and transparency of the original signal. Continuously variable, and detented Gain, Threshold, Attack, Ratio and Release controls offer a balanced combination of flexibility and precision to facilitate any number of desired effects, while a convenient feature like an automatic make-up gain ensures that the signal level remains optimal at all times. Additionally, 529 can be set to either feed-back or feed-forward operation mode to bring out vintage or modern compression characteristics respectively. Moreover, the compressor is endowed with the API's patented THRUST® circuitry to offer an extra punchy low end when needed.

All in all, 529 is an uncommonly versatile dynamics processor that can be as effective for mixing applications, as it can be for mastertering. Analog warmth abound.
