Helax

The AlSo Hellax is a mono

 

optical Compressor / Limiter. The Hellax is not the mono version of our Dynax 2 but a separate design with dedicated features. The Hellax has been designed to perform as your go-to compressor for voice as well as various sensitive instruments such as strings, brass, woodwinds, guitar and bass ..etc. It does so without producing any audible compression artefacts so commonly heard with most competitors. Nevertheless if used with more extreme settings the Hellax can live up to the task of producing impressive and creative compression effects. Like all Al.So products the Hellax’ construction is extraordinairy robust and is built to last a lifetime no matter if used in a studio environment or on tour . It’s entirely hand made in France and comes with an all metal chassis as well as highest quality controls and components only. The front panel controls are very intuitive and quickly taken in hand. The functions are: • POWER switch: turns the unit On / Off • VU meter: back-lighted in red it reflects precisely the reaction of the compressor according to the Attack and Release settings. It continuously displays the current gain reduction. • RATIO: Offers three different ratios. > LOW, about 3:1 > MEDIUM, about 10:1 > HIGH, infinite:1 Set to the latter, the Hellax performs as a Brickwall limiter and wont allow the signal to go beyond the level of the treshold setting. • BASS DRIVE (stepped): Adds a high pass filter into the detection chain of the Hellax. Three selectable frequencies are available: 100Hz, 200Hz and 300Hz. By activating this feature too much compression triggered by lower frequencies can be avoided. This can be particularly useful for instruments like bass or Cello and the like, more so if the user intends to apply a lot of compression. With the filter disabled (set to "Full“) the full input signal is sent to the compressor sidechain. • ATTACK: Sets the attack time of the compressor • RELEASE (stepped): Sets the release time of the compressor • COMPRESSION: Sets the compression treshold in a clockwise manner. Fully turned right is the max position. So it's operating in an opposite way than a standard threshold function: Left is less, right is more compression. • MAKE UP: Sets the output level of the signal after processing. • BYPASS: Lets you compare the original input signal with the processed one. When active processing is bypassed by relay. • BLEND: Allows for parallel compression, i.e. to mix the original signal (DRY) with the processed signal (WET) from 0-100%. The control is unstepped. Front panel The front panel controls are very intuitive and quickly taken in hand. The inscriptions are protected high quality serigraphs. The front panel pots of Hellax are very high quality components like Sfernice, ELMA and Apem potentiometers and switches. Electronics The electronics of Hellax have three main stages: The input Stage is based on a DC servo technology that eliminates the capacitors in the signal path offering a very low distortion and high fidelity signal. Then there is an Intermediate stage for the optical gain reduction. This is a technology that offers again a very low distortion rate of the signal. It allows to apply huge gain reduction rates without changing the signal tone or color. The output stage uses a Swoster transformer (UK) offering high signal fidelity along with very subtle colouration. The rear panel of Hellax hosts the IEC connector for the power cord, the 2 XLR input / output signal connectors and a 1/4" TRS connector for the sidechain input or link or 2 units for stereo operation.

different states10 mm thick front panel of Dynax 2Dynax 2's compressions rates Al.So Dynax2 is a stereo opto compressor with mono commands. The two channels are controlled by unique controls. The commands are: Compression rate, Attack, Release, Bass Drive, Compression rate and Make Up gain. This promotes the accuracy of the processed signals and offer more accurate results in terms of stereo image. Quality of construction: Dynax2 comes with a steel frame and a brushed aluminum front panel of 0.39 inches that guarantee strength and reliability in time, well above the average. Dynax2 like all Al.So products is extremely robust, fully hand made ??in France and high-quality components and controls. The inscriptions on the front panel are protected high quality serigraphs. The front panel controls are very intuitive and quickly taken in hand. The functions are: • POWER : On/Off of the unit from the front panel • Back-lighted VU meter Dynax2 VU has an original design as it's protected by homemade 0.39" Plexiglas. It precisely reflects the reaction of the compressor depending on the Attack / release settings. It has a quite unique design as it provides a lot of information under different device states: • In Bypass mode: It allows to compare the original signal input level with the Treaty ,it's back-lighted in dimmed blue, confirming the operating state of the unit. In this state, the VU will display the L/R signal level. • In active mode : it lights up fully and displays the output signal level of the left or right channel or the gain reduction level depending on the setting of VU switch . • In peak : it turns in bright red with a handy extra visual alert when the unit is located at a certain distance, like when recording on location. • 2 wholes under the VU: the left one allows the calibration of 0 VU for Compression, Limiter and Brickwall modes. The right one is used to calibrate the AntiDyna mode. • Sidechain (stepped): commands the compression in 3 way . > Stereo Position: by the stereo signal, as its name suggests > LEFT Location: by the left channel signal, i.e. when used for mono signals > EXT Position: the compression is controlled by the input signal connected to the TRS 1/4 " jack on the rear panel. • Bass Drive (stepped): A filter that controls the sidechain compression above the displayed frequencies 100Hz , 200Hz and 300Hz. In result, a higher compression can be applied while maintaining the very low ends. When set to Full position, the sidechain filter is disabled. • ATTACK: sets the attack time of the compressor • 4 compression ratios : COMPRESSOR about 4:1, LIMITER : about 10:1, BRICKWALL: Infinite : 1 (cannot exceed the threshold) and ANTIDYNA: proprietary compression mode. A compression, limiting and over-compression function. When Attack and Release times are set short, the strong and weak signals become lowest and the average signals become loudest. It is a creative function. • RELEASE (stepped): sets the release time of the compressor • BYPASS: let compare the original signal with the processed one. When active, it relay bypasses the input and output signal. • Compression: sets the compression ratio clockwise, fully turned right is the max position. So it's operating in an opposite way than a standard Threshold function. • MAKE UP: sets the output level of both channels after being processed • ST BAL: fine calibration by screwdriver of the left / right channels The front panel pots of Dynax2 are very high quality components like Sfernice, ELMA and Apem potentiometers. The electronics of Dynax2 have three main stages: > The input Stage based on a DC servo technology that eliminates the capacitors in the signal path offering a very low distortion and high fidelity signal. > The intermediate stage with gain reduction opto cell. This technology offer here again, a very low distortion et offers very high reduction gain without altering the signal tone. The optical cell is generally synonymous with slow compression. This is not the case with DYNAX 2 that is known for its fast compression! > Output stage by SOWTER (UK) transformers offering high signal fidelity while having a very subtle and silky musical coloration.

Dynax M
Specifications like Dynax 2 but more precise frequency points for the highpass filter and very low ratio setting "soft compressor" for gentle dynamic taming. No antidyna setting like the Dynax 2. For further informations see Dynax 2.
