Co-developed with Manley Labs, the UAD Manley Variable Mu Limiter Compressor Plug-In is now available exclusively for the UAD Powered Plug-Ins platform and Apollo audio interfaces as part of UAD Software v7.11.

Manley Variable Mu Limiter Compressor Plug-In — $299

The Manley Stereo Variable Mu Limiter Compressor has been Manley Labs' flagship compressor since 1994. The Variable Mu’s Class-A, tube and custom transformer-driven design epitomizes hand-made boutique craftsmanship. It’s considered the gold standard among mixing and mastering engineers thanks to its smooth, transparent dynamics control, and ability to add clarity and cohesion to stereo buses or an entire mix.

Developed under Manley Labs’ rigorous scrutiny, the Manley Variable Mu Limiter Compressor plug-in for UAD-2 hardware and Apollo interfaces is a thorough emulation of this legendary tube limiter, and is based on the coveted “6BA6 T-BAR Tube Mod” unit.

“After months of hair-splitting measurements and listening tests, we are confident and proud of the faithful emulation Universal Audio has made of our revered Manley Variable Mu Limiter Compressor,” says EveAnna Manley, President of Manley Labs. “The UA software engineers responded to our observations and scrutiny with eager dedication to make this plug-in one of the absolute best models they have achieved to date. Our ears confirm it.”
