The ultimate dynamic control
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. To explain the advantages of discrete circuitry we’d like to present a comparison that might seem a little odd at first: audio technology vs. cooking! If somebody uses instant meals exclusively, he will have to accept whatever comes out of the box. A creative cook, however, focuses on his own special recipes and ingredients.

In this respect, integrated circuits (ICs) are pretty similar to packet soups: they are cheap, mainstream and they simply do not match haute cuisine. So if you want to design an analog audio device 100% according to your own demands and ideas without any compromise, there will be no way around a discrete design. The alpha compressor follows this philosophy consequently. Not only all audio paths, but also the power supply, sidechain and even the driver for the LED meter have specially been designed for this unit, based of the exclusive use of discrete components. A truly unique recipe! In addition, our mastering compressor operates in permanent class-A mode. This means that the transistors are always conductive, resulting in the absence of crossover distortion and providing a pristine sonic base: the general sound character is always wide, open and transparent.

Integrated MS Matrix:
As an alternative to standard stereo operation you can process the mid and side signals, opening up completely new options for your work! M/S technology is commonly known as a variant of stereo microphoning. This technique uses a microphone with cardioid pattern for the middle signal (M) and another one with bi-directional pattern with an offset of 90° for the side signal (S). The main advantage of this technology is its mono compatibility. FM radio stations use M/S technology for transmitting stereo signals exactly for this reason.

To create M/S signals, the left and right channel of the stereo sum are added to generate the mid (M), whereas the side (S) is created by subtracting the right from the left channel:
M = L+R
S = L-R

To decode an M/S signal back into stereo again, M is added to S for the left channel and S is subtracted from M for the right channel:
L = M+S
R = M-S

The integration of an M/S encoder and decoder into a compressor generates new potentials that classic linked stereo compressors can hardly offer. One of the main advantages is the possibility to process the middle and side signals separately. This way you can make the center more compact without corrupting the original stereo spectrum, for example. Of course it is also possible to enhance the presence of the side signals in an already finished mix. The stereo width can be influenced fast and effectively, too, and it is also possible to compress specific parts of a mix that could not be selected in a stereo mix as precisely as it is possible in M/S mode.

Feed forward and feedback
The type of compression can be chosen for each channel individually, making two different compressors available at the push of a button. This function makes it possible to switch the feed of the sidechain alternatively behind (feedback) or in front (feed forward) of the actual compressor section. It has an enormous effect on the character of the compressor: While processing in feedback mode is smooth and even, switching into feed forward mode will result in a clearly stronger and harder kind of compression.

From the technical point of view this function mainly influences the characteristic curve of the ratio value. In feedback mode it goes up to a moderate ratio of 1:2.5. In contrast, the feed forward mode provides much higher values which also allow limiter settings and even negative ratios (i.e. loud signals will be reduced even more). Small changes in dynamics can generate a high amount of gain reduction. The values of the attack controller also change noticeably in feed forward mode, as they are almost twice as high as the values shown on the scale.
