Kultrumm 436c represents the qualities of the legendary Altec 436c compressor RS124 version. Developed in the fifties by the Altec company, the model 436 was used both for broadcast, PA, and in Abbey Road studios. There, in the early 1960s, engineers modified the original units for greater versatility. Years later, he would be immortalized in musical productions such as Revolver and Sgt. Pepper's Lonely Hearts Club Band, to name a few. In this way, it managed to become a cult compressor.
Kultrumm 436c fully respects that spirit by incorporating mods to achieve versatility and precision. It is a powerful tool for recording, mixing and, especially, mastering. The 436c compressor is part of the equipment of the best studios worldwide, given that its versatility is unavoidable in all musical genres.
A special and unique feature for a VariMu compressor is the Selk'Nams Threshold function.
When set to -9/-6, the sidechain function grabs -9/-6db of the audio material and compresses it, which leads to a very smooth and gentle gluey compression.When switched to 0 the Selk'Nam is in full compression mode.
