The Hellax is a mono optical Compressor / Limiter offering a very low distortion rate with side-chain filters and blend feature.
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.
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.
The front panel is clearly laid out which allows for easy operation:
RATIO: Offers three different ratios.
LOW, about 3:1
MEDIUM, about 10:1
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 "Fullâ€œ) 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.
