Elysia Alpha compressor – Rack Series

A modern Classic

The alpha compressor is a modern classic and becomes, since the release in 2008 a mighty tool for professional dynamics processing. Featuring innovative functions and providing absolutely uncompromising sound quality, it sets new standards for enhancing any kind of audio material. It offers M/S processing, parallel compression, limiters, as well as sidechain and audio filters, just to name a few.

Build Quality

The alpha compressor, just like all our products, is designed, engineered and handcrafted in Germany.
