Manufacturer's Description from Elysia

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.
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 its 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.
These benefits sum up in an audio quality that is beyond all doubt. Even when extreme settings are used, the sound characteristic stays clean and powerful. The alpha compressor 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.

 

100% Discrete Class-A

The alpha compressor represents the art of discrete signal processing consequently. ICs have to stay out without any ifs and buts.


Integrated M/S Matrix

As an alternative to standard stereo operation you can process the mid and side signals, opening up completely new options for your work!


Feed Forward & Feedback

The type of compression can be chosen for each channel individually, making two different compressors available at the push of a button.


Auto Fast

A switchable semi automation that always provides perfect attack and release on the basis of the values set by the user – even with complex material.


Audio Filter

The Niveau Filter is specialized in forming the tonal characteristics of a track very effectively without much of an effort.


Sidechain Filter

The alpha compressor features on-board frequency selective compression. This avoids complex routings in favor of an effective workflow.


Parallel Compression

Also available directly on the unit: the direct and the compressed signal can be blended in any desired relation by simply turning the mix controller.


Signal Matrix

The direct and the processed signal can be monitored individually or together by the push of a button in each channel (left & right or mid & side).


Soft Clip Limiter

Tames short and loud transients and smoothens the signal peaks, and thereby protects following AD converters from clipping.


Switchable Transformers

The sound of iron: yes or no? Both! The alpha compressor makes this option switchable, so you can decide for each track individually.


Analog Dynamic LED Meter

The gain reduction meter modulates its LEDs in their brightness in order to show the compressor’s action in an analog way: fast and with smooth transitions.


Passive Current Attenuator

The alpha's custom discrete gain reduction cell provides extreme speed, enormous bandwidth and superior sound.


T16 Heater

This system keeps sensitive parts of the discrete circuitry at a stable temperature and thus protects them against parameter aberrations.


Stepped & Matched Potentiometers

All potentiometers on the alpha compressor have 23 steps and are matched to build stereo pairs by a software routine that has been written just for this purpose.


VOVOX Sound Conductors

The internal audio cabling is also no place for compromise. By the use of VOVOX solid core the sound remains vivid, dynamic and punchy.

About Manufacturer

The beginning was an obsession. Would it actually be possible to build special gear with these features and sound characteristics? Well, since then Elysia has become a union of creative audio enthusiasts who have a clearly defined objective: the development and production of high-quality studio equipment featuring that certain something. We do not want to settle for the status quo and rehash existing concepts time and again. Our objective is rather to adapt our products to current demands in everyday studio life. The initiators of the company founded in Nettetal (Germany) in 2005 are Ruben Tilgner and Dominik Klaen. Affected by countless live and studio experiences as well as by over ten years of pro audio experience they finally created elysia in order to make their personal sound philosophy come true. Ruben looks back on many successful development projects: besides others, he has designed the Transient Designer, the GainStation and the MixDream for SPL. Based on his experience on the marketing sector, Dominik Klaen concentrates on communication, documentation and all topics related to product design. The independence of our enterprise enables us to follow extreme paths in our work. We like to try out a lot and are only satisfied when there is nothing left to improve. Besides, we never discard unconventional ideas airily we test all of them and never form our opinion before doing so. Our most important rule is that the ear always comes first, but we also like to please the eye by reflecting the inner values of our devices on the outside with an exclusive design. This is the basis on that our audio equipment is built. We set value on highest sound quality, exclusive use of top grade components, perfect operability and reliability, appealing product design, exemplary documentation and implementation of innovative features without any Voodoo, but with real profit for daily usage.
