The Manley Vari-Mu Black Friday deal is 46% off, $79, with the offer ending Nov 30, 2026, on Universal Audio's plugin version of the Manley Variable Mu Limiter Compressor.
The Manley Vari-Mu is a variable-mu limiter compressor plugin. Universal Audio describes it as an authentic emulation of Manley's flagship compressor, which is a tube and transformer-driven design the hardware maker has sold since 1994.
The maker says mixing and mastering engineers treat the original as a gold standard. It works on single tracks, stereo buses or a whole mix.
It is a gain reduction tool. Universal Audio says it applies smooth compression while adding warm harmonic content, without audible compression artifacts.
The maker also says it glues difficult mixes together and adds definition and fidelity to what you run through it.
It suits a lone source, say a bassline or the main vocal, and equally well a bus of strings or brass.
The maker says its home turf is the mix bus. That is where it is meant to unify a mix with a rich, hi-fi fit and finish.
The maker highlights these:
With the channels unlinked, Universal Audio says the Mid/Side processing is improved over the hardware and gives phase accurate stereo imaging.
The Dry/Wet Mix control is not on the hardware. It lets you blend the compressed signal with the dry one, which suits parallel compression on vocals and other sources.
If you want a compressor for the stereo bus, the linked mode and the Mid/Side option are the two settings the maker points to for stereo work.
