Dynax M meters behaviour in different states
10 mm (0.39") thick Aluminum front panel
AL.SO (for Alternate Sounding) Dynax M is an absolutely new tool for modern dynamics processing. Dynax M is
mastering version of the Dynax 2 with enhanced features dedicated to mastering tasks. It 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 soft compressing, compressing, limiting and side-chain filters, just to name a few of its features.
The Al.So Dynax M is in fact more than an ordinary mastering 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 M 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 M 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 mastering. A very powerful tool for professional dynamics processing. 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 M 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 M 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!
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 M offers four different compression ratios:
Soft compression (2:1)
Compressor (4:1)
Limiter (10:1)
Brickwall (infinite:1)

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

Dynax M 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.


  Stereo Optical Compressor with 4 compression rates: 2:1, 4:1, 10:1 & Infinite:1
  Extremely large time constant ranges
  Bass Drive or compression Sidechain filters 50, 100, 150, 200, 250 & 300Hz
  Sidechain Input
  Control through an external input signal, left channel signal or the stereo signal (sum of L/R channels)
  Hardware Bypass by relay, to compare the original and the processed signal in an absolute way
  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)
  Output transformers by SOWTER (UK)
  100% hand built with high-end selected components
  Designed by Olivier Bolling
  Compatible with 110/230 Volts 50/60Hz.

Note: if the unit is shut down or disconnected from the main power, the signal passes then by the Bypass relays. A very secure characteristic while live recording situations.
