The Manley Nu Mu Stereo Limiter Compressor uses the special T-Bar mod tube front end of the legendary Variable Mu® with same super smooth side chain and timing characteristics followed by a high voltage discrete and FET solid-state amplifying and output stage for a faster and punchier audio path. It is like a “clean” version of the Variable Mu, especially suited for modern digital and electronic music where you don’t necessarily need to color or mask the sound like we did in the early days of digital.
Featuring Manley’s new HIP function, the Manley Nu Mu finesses dynamic control to bring up lower level details without knocking the life out of exciting transients. Smartly engineered to build efficiently and esthetically designed to elicit ravishing compliments from your clients, both visually and ergonomically, the Manley Nu Mu breaks new ground in performance and value, all proudly handbuilt in California, of course!
The “HIP” control allows compression to happen at lower volumes (lower in the dynamic range spectrum), but leaves
the louder dynamics alone while still compressing the overall signal. You get louder soft sections with the original dynamics of the louder sections.
