Elysia Alpha Compressor

Stereo Compressor with M/S circuit and Parallel Compression

One for All

The alpha compressor is 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.

True Mastering Features

The circuitry is a completely new development which provides an amount of openness and clarity which can hardly be found a second time. Every part of the alpha’s signal processing is based on single transistors running in constant class-A mode, and even the sidechain and power supply use discrete circuits. All components are of the highest grade available and exclusively chosen according to their sonic excellence.

Build Quality

The alpha compressor is all about details. Every single of its many aspects – sound, features, circuitry, components, design, materials, manufacturing – has been thought over and over until there was just nothing left to improve.

Basically, every single part of this amazing compressor is custom, and most of these are made according to our own designs and specs. Only the best the market has to offer is good enough for the alpha, and it shows.

Each alpha compressor is manually built to order and tested by ourselves, here at our headquarters in Germany.

The alpha’s benefits sum up in an audio quality that is beyond all doubt. Even when extreme settings are used, the sound always stays clean and powerful. The alpha achieves perfect processing results for all different styles of music and assures the ‘this is it’ feeling of a finished song. Its enhanced functions exceed the potential of normal compressors by far and give you unimagined options for mastering and mixing.
