Unlock the Full Potential of Your Mix with the Manley Variable Mu Limiter Compressor
The Manley Variable Mu Limiter Compressor is a game-changer in the world of audio processing. This compressor features the innovative MS Mod, transforming the left channel into the "middle" and the right into the "sides," allowing independent compression of each phase component. Imagine squeezing the vocal, kick, snare, and bass (in-phase info) while maintaining the integrity of the out-of-phase program, resulting in a super-wide stereo image.
What sets this compressor apart is its all-tube, all-transformer design—a true all-American legend. The Variable Mu is the glue that binds your mix, turning it into a professional, final product. The inclusion of the High Pass Side Chain mod as a standard feature adds even more versatility to this iconic device.
MS Mod for Stereo Widening:
Independently compress the left and right channels for a super-wide stereo image.
All-Tube, All-Transformer Design:
The Variable Mu is a legend, using vacuum tubes and transformers for that classic, warm sound.
High Pass Side Chain Mod:
Enhance control and precision with the High Pass Side Chain mod, now a standard feature.
Soft-Knee and Limit Modes:
Soft-knee 1.5 to 1 ratio in COMPRESS mode, and sharper knee LIMIT mode ranging from 4 to 1 to an intense 20 to 1 for heavy limiting.
Ganged Input Control for Stereo Processing:
While having a ganged input control, it remains stereo-friendly. Perfect for final mix, 2-track, or mastering limiting and compression.
Versatile Distortion Control:
Creative distortion options by manipulating the Input and Output controls with little or no compression.
Although it has a ganged input control, the Variable Mu is versatile for stereo applications. Separate threshold and output controls allow for precise adjustments.
The Manley Variable Mu Limiter Compressor stands as a best-seller for a reason—it's the go-to choice for mastering studios and has contributed to numerous hit records. Elevate your music with the sweet cream of tube magic and give your mix the embrace it deserves.
