TAKE A LISTEN
Easily Add Stunning Polish
Treat your source material with velvety-smooth gain reduction, while infusing warm harmonic content, free of audible compression artifacts with the Manley Vari Mu Limiter Compressor plug-in and add a variable gain compressor with stunning transparency to your studio.
Enhance Tracks and Glue Mixes
The Manley Vari Mu Limiter Compressor plug-in can be used on single instruments such as bass or a lead vocal, or on subgroups like strings or horns. But its raison d'être is on the mix bus, where it can unify your mixes with a rich, hi-fi fit and finish.
Polish your Mixes with Powerful Controls
Parameter linking allows simultaneous adjustment of both channels with stereo signals. When unlinked, the plug-in's Mid/Side processing is improved over the hardware, giving you phase accurate stereo imaging. Use the High Pass Sidechain filter to reduce low-end pumping — letting you compress, say, overheads, while retaining punchy bottom-end. Dry/Wet Mix offers easy parallel compression — perfect for polishing vocals and more — while Headroom lets you optimize the Variable Mu’s overall level to your playback system.
“If you've got a ragged mix, this plug-in will give it a big hug. It's a stunning emulation of our Variable Mu hardware, right down to the last detail.”
– EveAnna Manley President of Manley Labs
“The Manley Variable Mu is one of my go-to compressors for all types of sounds – especially when I’m looking for an upfront, in-your-face tone. It's fun to distort too.”
– Mike Larson (Pharrell, Daft Punk, Kendrick Lamar)
“I used to lament that I had only one Manley Variable Mu. Thanks to UA, those days are in the past! Now I'm like that little old lady on the hot sauce commercials — I put that s*** on everything!”
– Phil Tan (Mariah Carey, Ludacris, Rihanna)
“Three different hardware versions of the Manley Variable Mu have lived in my gear racks since the ’90s. Now the UAD version captures the same unique feel that the hardware adds to my mixes.”
– Mark Needham (The Killers, Neon Trees, P!nk)Customer Reviews

This is Really Something.
I have years of experience of Manley Hardware in the studio recordings. For my professional bass player career, Manley is the finest compressor I've ever seen. I've known and worked with other historical superior gears such as 1176, LA-2A, dBX, however, Manley Mu is superior in this current music scene.
Now This is in my plugin library!
I also have other company's emulation for Mu, they never satisfied me unfortunately, very far from the original hardware.
This UAD version is real. No doubt.D. Clements
Manley the MU Monster!
OMG! This MU compressor is unbelievable! I am currently using this UAD plugin on the mix bus at the end of the chain. It has extra options available that others do not. The input gain control is such a great feature to have. Between the input gain, threshold, and output controls, you have great signal control flexibility at your fingertips. The metering is accurate. The fidelity of the plugin is very pleasing to the ear.

Instant glue
Didn't know what to expect from this one since I never used the original hardware. I instantly loved it, instant glue and polish. IMO Not for every music style , sounds great.

This plugin adds noise/hiss to the signal
I am super upset that I haven’t properly tested the plugin before purchase, There should be an option to disable the noise in a digital recreation of a plugin. Useless for me .
