API 529 Shop all API Audio

The 529 is a 500 series compressor carefully designed to deliver a wide range of compression options with the signature warmth, clarity and punch of the API brand.

Based on the unprecedented success of the 2500, the 529 takes many of the features and controls from API's famous stereo compressor and puts them into the first dual slot 500 series module from API.

This stereo compressor features API's patented THRUST® circuitry for a punchy low end, along with an Old/New switch that lets you choose between classic and modern compression characteristics: Old for vintage-style feedback compression and New for today's more common feed-forward compression. The Auto-makeup Gain button lets you adjust ratio and threshold controls without affecting the output level.

Using API's discrete op-amps and transformer technology, the 529 delivers the legendary analog sound of API.
