Manley Labs Stereo Variable MU Limiter Compressor Mastering Version with M/S & T-Bar Mod

The Stereo Variable MU Limiter Compressor Mastering Version with Mid/Side and T-Bar Modification from Manley Labs is a dynamic signal processor using two single-pentode tubes wired in triode for peak reduction and compression. The tube circuit is constantly re-biased by the vacuum tube rectified side-chain control voltages, resulting in a smooth change in gain. This mastering version replaces all conductive plastic pots with Greyhill rotary switches. The 1% metal-film resistors on the Greyhill switches not only provide recallability, but also deliver an improvement in sound quality.
