The Variable Gm compressor limiter is modeled after a design which has made the history in the audio compression world, with a sound limpid, crystalline, and crisp at the same time, where compression starts low and increases gradually, so subtle and natural, but punchy when driven hard.
The unit is quieter than any other tube compressor and it manages to provide the vacuum tube warmth that tube circuits are renowned for without adding any negative artifacts or noise.
The Variable Mu technique enhances the vocals and individual instruments by being unobtrusive, gently warming sounds, impressive on overall mixes.
The 'Stereo - Dual Mono' working mode ensures the widest freedom of use for the most demanding studio applications, as a tracking or mastering compressor.
The external special custom order 'Surround Link' allows several units to be linked for Surround 5.1 or 7.1 operation, making this compressor the ideal choice for this application ranges to set a quality standard.

An all valve-based equipment entirely hand-crafted.

The components used are all selected with the strictest tolerance, and tested by ear.

It broadens the base of your mixes.
