Overview

AL.SO (for Alternate Sounding) Dynax 2 is an absolutely new tool for modern dynamics processing. Dynax 2 has a
complete genuine design, so it's not a clone or a new version of any other existing compressor nor limiter. Featuring
innovative functions and providing absolutely uncompromising sound quality, it sets new standards for  enhancing any
kind of audio material. It offers compressing, limiting, side-chain filters and sound shaping, just to name a few of its
features.

The Al.So Dynax 2 is in fact more than an ordinary compressor/limiter as it's not only a very punchy and groovy
dynamics processor, It is designed as a Dynamic Sound Shaper, It Offers a very analog, warm and silky coloration.
Based around very low distortion circuits, the Dynax 2 allows a wide range of effects. The smoothest and most
transparent compression to the harshest and most spectacular sound designs, a creative tool meant for creative
sound engineers. Even when extreme settings, the sound characteristic stays clean and powerful.
The Dynax 2 can achieve perfect processing results for all different styles of music and assures that feeling of a
finished song. Its enhanced functions exceed the potential of normal compressors by far and give you unimagined
options for recording, mixing and sound design. A very powerful tool for professional dynamics processing. A Dynamic
Sound Shaper, a creative tool meant for creative sound engineers.
Both Attack and Release pots offer a graduated change of values to reshape the sound and create a new envelope.

The circuitry design of the Dynax 2 is totally based on discrete analog technology and is a completely new
development providing openness and clarity which can hardly be found with most other compressors. Every part of the
signal processing is based on high grade selected Op-amps, using different solutions like DC servo and particular
transformer driving circuitry and linear power supply in order to avoid switching PSU artifacts. All components are of
the highest grade available and exclusively chosen according to their sonic excellence. Last but not least, the output
transformers of incredible quality made by SOWTER ( UK)

Both channels are controlled by unique commands, offering more accuracy and faster recall of the parameters. The
1st thing you'll notice is the distortion-free compression as it's as low as 0.005% (1kHz +4dBu). You don't compress
distortion but ONLY dynamics!

Dynax 2 has a feed forward design, it's probably the fastest Opto Compresor/limiter you ever tried, capable of offering
extreme over-compression or pumping effects. Very easy to set, choose the Ratio, choose attack & release and add
compression, you're ready to go! The proprietary Antidyna mode is a very one of the kind effect as it compresses only
mid level signals, lowering the highest and lowest ones. You'll love this effect for parallel compression or sound
design.

An oversized power transformer, conductive plastic potentiometers, internal temperature stabilizers for critical
components as well as special current feedback amplifiers are part of the technical finesse. The combination of these
elements results in a pristine signal quality and guarantees clean and powerful sound characteristics, even when
extreme settings are used.

The Dynax 2 offers four different compression ratios:
• Compressor (4:1)
• Limiter (10:1)
• Brickwall (infinite:1)
• AntiDyna: an innovative new mode designed by Olivier Bolling which literally "over-limits" the sound in a "funky-to-
trashy" way

Quality of construction
The front panel is a 10 mm (0.39") thick solid brushed aluminum engraved piece of metal. A steel frame to guarantee
strength and reliability in time, well above the average. The inscriptions on the front panel are protected high quality
serigraphs.

Dynax 2 like all Al.So products is extremely robust, fully hand made ​​in France and high-quality components and
controls. Each unit is individually and precisely checked and listened to before being shipped, as only sound matters!

VU-meter lighting displays both output level or gain reduction. Over modulation cleverly turns the blue back-lighted
meters to a strong red. Clearly visible even if the unit is placed a distance.

  Bandwidth:10Hz / 30 kHz at +/- 0,1dB
  Bandwidth 10Hz / 65 kHz at +/- 1 dB
  Bandwidth with a gain reduction of 10dB: 40Hz / 40 kHz at +/- 1dB
  Harmonic distortion of 3rd order at 1 kHz, +4dBu: 0,005%
  Harmonic distortion of 3rd order at 1 kHz, +4dBu, with a gain reduction of 10dB  0,02% (time constantes median settings)

Petite histoire du Dynax2
Le premier prototype de Dynax a été dessiné puis réalisé en 2002. Le but était de créer un compresseur analogique différent de ce qui existait déjà . En 2002, Olivier
Bolling, concepteur des machines AL.SO, était directeur techniques des célèbres studios Plus XXX (membre du Word Studio Group). Les studios étaient alors
équipés des meilleures machines ( périphériques , enregistreurs et consoles), modernes et Vintages. Autant dire qu’il y avait là  la possibilité d’étalonner Dynax par
rapport aux compresseurs existants ! Et que lesingénieurs du son d’exception étaient là  pour donner leurs avis ! Dynax fut alors utilisé pour une quarantaine d’
albums nationaux etinternationaux .

L’ idée de départ était de construire le chainon manquant, un compresseur efficace qui n’ agisse que sur la dynamique et qui n’ ajoutepas cette distorsion
harmonique, caractéristique de bien des compresseurs, ce qui bride si souvent le contrà´le de la dynamique.Un compresseur mono, qui pourrait être utilisé sans
que l’auditeur final puisse savoir si le son a été compressé ou non !

Pendant le développement, nous nous sommes rendu compte des possibilités étendues que la machine offrait et à  la compression « transparente », nous avons
ajouté la compression « créative ».
L’ AntiDyna est une partie de cette fonction créative. C’est une erreur lors du montage d’ un prototype qui a permis de mettre au point cette courbe de compression si
particulière.

Les premières machines furent présentées au salon AES en 2006 ( Paris et San Francisco). Une première série de machines mono (Dynax) furent produites, mais
devant l’insistance des ingénieurs du son et des musiciens, la machine devint Dynax2 , permettant ainsi la compression de mixages ou de boucles stéréo.

Le test final du Dynax2 fut effectué dans un studio de Mastering ( un environnement qui avait été celui d’ Olivier Bolling pendant plusieurs années). Le test fut réalisé
à  Masterdisk Europe, part l’ingénieur du son Eric Chevet qui aussità´t remplaça son compresseur (un grand classique du Mastering) par un Dynax2.

Dynax2 a été présenté au public lors de l’AES de Vienne en 2007.

Cette machine, conçue pour le studio, devenait une alternative majeure pour le mastering… puis pour la  sonorisation grà¢ce à  Antoine

Crespin (Future Acoustique) et Xavier Stelly qui installèrent le Dynax2 sur le bus de mixage façade du grand chapiteau de Jazz In Marciac en 2008 (un vrai test de
fiabilité, il y fait parfois plus de 50°C).

Dans les semaines qui suivirent, et après un essai de la quasi totalité des machines concurrentes, Madje Malki , Potar Hurlant et Bon Esprit Backline achetèrent
plusieurs machines pour les tournées de Bernard Lavilliers, Camille, Yannick Noa ou encore le groupe Justice.
