03In depth

Vintage Mix Bus Compression Character

The plugin is based on a modeled unit from the center sections of early Oxford consoles. Antelope Audio says the original design was a modified dbx 161, and that many later hardware and software clones altered that sound over time. This version aims to recreate the original circuit faithfully.

The compressor is intended for the master track, where it can be used at the start of a mix or as a final step once the other elements are in place. Its Auto Fade feature, found on the original center sections, has an adjustable release rate in seconds, which lets you shape how the compressor recovers.

Sidechain Filtering and Parallel Compression

A sweepable sidechain filter helps prevent sub-low frequencies from triggering the compressor and over-compressing the mix, a common issue in modern music with heavy low end.

A Mix control sets the blend between the compressed and unprocessed signal, which allows parallel, New York-style compression on individual tracks as well as on the mix bus.
