Compressor TYPE

The 529 Compressor can be set to operate in two circuit topologies that determine where the signal

that feeds the RMS detector comes from:



OLD: Feed-Back topology: The RMS detector receives the signal from after the VCA



NEW: Feed-Forward topology: The RMS detector receives the signal from before the VCA

NEW (Feed-Forward)

In a feed-forward compressor, the RMS detector normally gets its signal from a split of the input sig-

nal. (The detector path can alternately get its signal from a Side Chain Input.) With this method, the

RMS detector sends a signal to the VCA that is an exact ratio of the desired compression set by the

RATIO control. This is how many new VCA based compressors work. This can yield more aggressive

compression and a harder, more affected sound.

OLD (Feed-back)

In a feed-back compressor, the RMS detector gets its signal from the output of the gain reduction de-

vice (VCA). This is how older API 525, 1176 type, and 660 type compressors work. This yields a

smoother, softer, more transparent sound.
