Reference Tube Channel Strip


Introducing the Manley CORE®, an innovative channel strip that combines Manley's Greatest Hits with fresh technology. Built upon a 25-year legacy producing revered recording studio equipment for top recording engineers and musicians, Manley Labs has combined its CORE technologies to give you maximum flexibility at an affordable price. The COREs strength flows from its Class A high-voltage tube micpre and ELOP Compressor, into its sweep able mid EQ with high and low shelves, and is focused by a fast brick-wall FET limiter. An intuitive front panel layout allows you to concentrate on creativity instead of being lost in a sea of knobs. Easy to use, musical and forgiving, the CORE makes it easier than ever to cut a great sounding track.

Manley’s experience and insight working with the industry’s top recording engineers and musicians culminates in the CORE. At this price, there is no other channel-strip with higher headroom or more seductive sound than the CORE. 

Handcrafted in the USA, built like a tank, built to endure, the epicenter of your recorded art will be the Manley CORE.



The signal enters through our renowned hand-wound MANLEY IRON® input transformer with nickel laminations in a mu-metal can. The tube amplifying stage is the latest implementation of our famous Class A circuit topology found in the VOXBOX® and Manley Dual Mono & Mono Microphone Preamplifiers. This all-triode vacuum tube circuit runs on a regulated 300 Volt B+ supply yielding huge headroom and relentless output drive capability.
