The Perfect Glue for Mixing and Mastering

The Pulsar Mu emulates the smooth, low-distortion compression of sought-after variable-bias hardware like the Fairchild 660/670, Altec 436B, Abbey Road RS124, and Manley Variable Mu. Like the hardware that inspired it, the Mu exhibits unprecedented transparency, even when you push the gain reduction to the max. And its ability to lend cohesion — that elusive "glue" — to your buses, mixes, and masters is unparalleled. Armed with Pulsar's Topology Preservation Technology, this plug-in can be used for leveling, limiting, or just to add a touch of analog warmth via its emulated tube signal path. Mu goes further than its hardware forerunners, arming you with lookahead limiting, a flexible sidechain EQ, mid-side processing, an external sidechain, and modern metering. If you're craving the one-of-a-kind sound of a variable-gain tube compressor, the Pulsar Mu is sure to put a smile on your face.

A transparent but musical compressor

Many of us here at Sweetwater are analog junkies, and variable-bias tube compressors represent a Holy Grail of sorts. Their transparent, yet eminently warm, sound is nothing short of astonishing. The soft, musical way they tackle transients is the stuff of legend. And the way they add movement while still respecting a source's natural dynamics can't be replicated with any other type of compressor. So, what can you do with a variable-bias compressor? Well, its most oft-used application is as a mastering processor, lending a studio-quality sheen and glue-like warmth to your mix. You can also use it to add cohesiveness to your drum bus, while also adding girth to room ambience. Variable-bias compressors can also add body and consistency to snare drums and liven up dull guitar tracks. They're also pure magic on vocal tracks, injecting them with juicy analog warmth.

Previously, variable-bias tube compressors have been out of reach for all but the biggest names in the studio world. But now, thanks to Pulsar, you can get one of these legendary units right inside your DAW.

Does things the original hardware can't

The Pulsar Mu doesn't just emulate a vintage piece of hardware — that's just the starting point. You also get a full-featured sidechain EQ section for controlling how the compressor responds to specified frequencies. A modern metering section enables you to fine-tune your compression settings, representing the waveform and gain reduction both over time and instantaneously.
