Manley Core

Product Description

THE CORE - a killer new channel strip from Manley Labs. Huge headroom: fantastic sound: great combination of features: rugged MADE IN THE USA build quality and all at a very affordable price.

The new 2U CORE has an intuitive front-panel making it easy and super fast to adjust your settings. With UK pricing at less £1500, there's never been a better time to have a piece of Manley professional gear in your rack.

The CORE's signal path starts with a fixed 3:1 comprerssor before the mic-pre (Class-A tub  e based original design based upon circuitry in the CORE's big brother - the Manley VoxBox) making it virtually impossible to overload. There's a handy DI which is very similar to the one used in Manley's SLAM! which is an all-discrete solid-state circuit with 10 Meg Ohm impedance so, great for high impedance guitars, basses and keyboards.

The EQ section is a new solid-state BAXENDALL design for the company with high and low shelves as well as a sweepable midrange bell curve with a handy range switchable between 100Hz - 1kHz and 1kHz - 10kHz.

There's also a fast BRICKWALL FET limiter with a fixed attack continuously variable threshold and release plus output makeup over a 10dB range for gain control, and an uber cool large analogue VU meter where you can switch between displays of input, output or gain reduction levels.
