Product Description

(Special Order. Final Sale.)

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.
