Introduction

The new 529 Stereo Compressor combines the

unmistakable sound of API's compression technology

with the convenience and popularity of the API 500

Series format.

Carefully designed to deliver a wide range of

compression options, the 529 delivers warmth, clarity

and punch, whether used for subtle adjustments or

heavy compression effects.

Based on the unprecedented success of the 2500, the

529 takes many of the features and controls from

API's famous stereo bus compressor and puts them

into the first dual slot 500 series module from API.

Using

API's

discrete

technology, the 529 delivers the legendary analog

sound of API.

The 529 is a two-channel, stereo-linked dynamic

processor

designed

compression and compression of any stereo audio

source. The audio input signals from both channels

are combined in a true-RMS power summing fashion

to create the compression control signal for the

detection path. Then, the resulting compression

signal is applied evenly to both channels for proper

balance. All front panel settings control both channels

simultaneously.

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

3-position KNEE switch adjusts the shape of the curve at the onset of compression for an "over-easy"

type compression resulting in a very natural, uncompressed sound or a typical sharp knee type that

lends itself to a much more severe limiting effect.

The Auto MAKE UP gain function lets you adjust ratio and threshold controls without affecting the

output level. Alternately MAKE UP gain can be set manually.
