Enhance Tracks and Glue Mixes

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.

This is The Real Deal !!

As a owner of the Vari MU mastering version, I can only say that this plug in is very very close to the real hardware unit. May a 10% less than the character of the hardware, but just really close in every character.
And I must say I love it, its just easy to dial in on a bus or entire mix...a really game changer!

Manley Variable Mu Limiter Compressor

This is a very good compressor limiter. I use it for mastering, which results in a warm and saturated sound, giving the mix a studio quality. Despite writing dance music, I really like this compressor.

Still good

It reminded me of the first time I used the actual device. Or rather, it's like a stronger magic. It just broadens the range of options with other UAD Plug-ins.
