Manley Vari-Mu

Add tube compression royalty to your mixes

The Manley® Variable Mu Limiter Compressor plug-in gives you an authentic emulation of Manley's flagship compressor, so you can add definition and fidelity to individual tracks, stereo buses, or an entire mix.

As Manley Labs' flagship compressor since 1994, the Vari Mu is a tube and transformer-driven classic that exudes handmade craftsmanship and is the gold standard among mixing and mastering engineers. The Manley Variable Mu Limiter Compressor plug-in gives your stereo buses or your entire mix the same clarity and cohesion as the high-end hardware.

• Add definition and fidelity to individual tracks, stereo buses, or an entire mix
• Glue together difficult mixes with signature Manley tube compression
• Link channels for a precise, perfectly matched stereo image
• Select from Left/Right or Mid/Side operation for precise control of stereo imaging
• Use the plug-in-only Dry/Wet Mix control to easily dial in parallel compression

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.
