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.

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.

Great to have in your arsenal!

When you want that subtle extra punch at the master bus, this should be appreciated by many music producers/engineers. Usually I would use it for only around 0.5dB reduction/gain, but still it makes a huge difference!

Manley Variable MU Limiter Compressor

I Don't know what the emulation is, but the sound is muddy, warm and grate. 5 points for developers.

Love it, lifts my mixes to another level

I have been using the Manley Variable Mu compressor/limiter on most if not all of my mixes since I got it, and I love it! I usually start with a mastering preset and then just tweak it a little, get it so that the level of gain reduction is such that the meters move just a bit. My mixes definitely sound a little tighter or more cohesive. I love this plugin for mixing compressor duties!

great sounding compression

Lovely comp, does exactly what one wants it to do, slight compression, almost invisible, but when you bypass it, you want to activate it asap.

Excellent, it's Manley

I've used my UAD Manley Vari-Mu for a few weeks. Emulation is perfect, it sounds great, it's easy to set, and can be used on everything. At full price it's a good deal, at this discount, you have to consider just getting it unless you've got the hardware.

Realistically this is one of the few plug-in purchases that changes my audio so much to the better all by itself. And I'm not compressing by more that 3 dB. Insert Vari-Mu and there's the sound.

I'm running mine in stereo, but the special option to change to M/S in, out, or both is a relatively rare feature.

Good, but was expecting more.

It doesn’t wow me like some other UA plugins. Quite effective on slower, non- transient heavy material, however probably wouldn’t be my first choice for that.
Mostly invisible (positive or negative, you decide) up to 2db of reduction, however any more than that i’ve found the action to be slightly unmusical.

The Best I've Come Across

The Manley variable mu compressor is robust and produces the good vibrations that I had hoped for. You can't go wrong with this compressor.

Very Good, but Handling could be better

I am using the Manley now instead of the SPL Iron i used before in the Master chain. The Manley has a much clearer sound. But i found the SpL better in the handling as a plugin. Both work very well for me as Mastering Compressors. I would like a compressor not with the hardware front usage in a plugin but with a good software handling and the sound of good hardware.
