Manley Nu Mu Variable Mu Stereo Compressor - Used From Manley
Building upon a proud heritage, the Manley Nu Mu merges the “T-Bar mod” all-tube front end from the legendary Manley Variable Mu® and makes it standard followed by a new high voltage all-discrete solid state audio chain for the smoothest dynamics action coupled to the punchiest sonic path. In Used, Mint condition

Manufacturer's Description from Manley
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 aesthetically 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 hand built in California, of course!
“HIP” Control
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.
Features:
- Manley IRON® input transformers
- 4 x hand-matched 6BA6 vacuum tubes
- Balanced XLR inputs & outputs
- Manley HIP function raises soft dynamics without squashing louder passages
- High Voltage Switched Mode Power Supply custom designed for our vacuum tube audio circuits
About Manufacturer
The MANLEY brand has been around since the late 1980's. Manley's first commercially available products were upper echelon high-fidelity vacuum tube amplifiers and preamplifiers constructed at the old Vacuum Tube Logic of America factory.
In this history lesson, we'd like to direct special focus on our people at Manley Labs. The people whose years of dedication, service, and expertise bring you people, our customers, these products. It's all about the people...
On January 30, 1989, a 20 year old EveAnna on sabbatical from her studies at Columbia University met the crew and was hired on to the production team. Baltazar Hernandez, already with two years experience, taught her how to solder in those first few days. It was in 1989 that the first Manley professional products were developed, starting with the original 1u Reference 60dB Microphone Preamplifier and soon followed by our Manley Enhanced Pultec and Mid Frequency Equalizers. Baltazar and EveAnna, busy building gear, were soon joined by Saulo and Ramiro. Just next door, Elias was employed by a printed circuit board maker later brought into the Manley Labs fold when in 1993, Manley Laboratories, Inc. became a separate entity apart from VTL. The new Manley Labs factory at 13880 Magnolia Ave. in beautiful and bovine Chino, California was outfitted to house the Manley HiFi and Pro Studio manufacturing as well as the Langevin production lines, our newly acquired machine shop, and printed circuit board facilities.
