The AT-101 is the result of 4 years development based around the Fairchild 670 Stereo Limiter/Compressor it is a blend of modern technology and traditional construction, the original was developed during the late 50’s and has gained a somewhat mythical status, in both recording studios and value. Favored by many recording engineers for its natural uncoloured sound, original units typicaly command high prices. The AT-101 shares exactly the same circuit and components used in this technology. The aim is to breathe life back into a product that has for many years been unavailable. The goal is to make this unique brand of audio compression equipment commercially available to everybody. Many attempts have been made to recreate it, mostly by [now] established American manufactures using parts of the circuit and different tubes in a smaller box. The AT-101 brings together 50 years of established technology using state of the art low noise components and returns classical methods of audio compression back to the studio.

analoguetube builds and manufactures the AT-101 using traditional electronic methods with parts that are sourced commercially and that are commonly available. These units have been built by hand as close to the original as possible using standard high quality components and are warranted to be free from manufacturing defects for the life of the equipment from the original date of manufacturer.
