Forget plugins: Grab a knob and turn up the magic.
This versatile VCA Compression with real creative saturation -- not mathematical calculations -- will add professional-grade compression and harmonic character to your 500-series rack.
The Locomotive Audio Powr-Mu is hand-built in St Louis, USA with premium-grade components. This variable-Mu compressor delivers smooth, transparent gain reduction across vocals, drums, bass, and full mixes.
The “Powr” switch engages a custom harmonic saturation circuit, adding warmth, presence, and controlled grit for creative mixing or vocal coloring.
With a variable ratio (1:1 to 20:1), dedicated attack and release controls, threshold adjustment, makeup gain, and a true bypass switch, the Powr-Mu offers precise, hands-on control without menu diving.
Engineered for high-headroom, it’s a favorite among engineers who need a single module that covers everything from transparent leveling to characterful compression.
Caveats: Tube-based 500-series units produce more heat than solid state units, so ventilate your system adequately. Tube-based 500-series units also consume more power, so a quality 500-series chassis is always recommended.
