Manley Core

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.

48V Phantom power switch
120Hz High Pass Filter switch
Phase Invert switch
Input Attenuator (Variable Pad)
Mic Pre Selectable Gain 40dB or 60dB
Line Amp Selectable Gain 20dB or 40dB
DIRECT IN: Similar to the DI in the Manley SLAM!®, this all-discrete solid-state circuit with 10 Meg Ohm input impedance is perfect for guitars, bass, keyboards, etc.

COMPRESSOR:
Featuring our successful ELOP® technology also found in our famous Manley VOXBOX®
Compressor is uniquely before the Mic Preamp making it virtually impossible to clip
Ratio 3:1
Continuously variable Attack, Release, and Threshold controls
Silent Bypass switch
