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
