Get A Versatile Channel Strip With The Manley CORE Reference Channel Strip The remarkably intuitive front panel combines musical and forgiving circuitry that allows the musician to concentrate on his performance instead of being lost in a sea of knobs. Ease of use and intelligently chosen operating points make it virtually impossible to cut a bad 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 Manley's 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 and 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.
