Manley Core is a combination mic preamplifier, compressor, equalizer, and limiter.
Front panel controls include a 48-volt phantom power switch,120Hz highpass filter switch, phase invert switch, input attenuator (variable pad), mic pre selectable gain (40 dB or 60 dB; total gain >70 dB), and line amp selectable gain (20 dB or 40 dB). The mic/line preamp includes hand-wound Manley IRON input transformer with nickel laminations in a mu-metal can, Class-A tube amplifying stage, circuit topology (similar to the Manley VOXBOX and Manley Dual Mono and Mono Microphone Preamplifiers), all-triode high voltage vacuum tube circuit, and regulated 300 Volt B+ supply.
The compressor section, with a 3:1 ratio and placed before the mic preamp, features Manley’s ELOP technology (also found in the Manley VOXBOX), continuously variable Attack, Release, and Threshold controls, and a Silent Bypass switch. The equalizer offers low and high Baxandall shelves (80 Hz and 12 kHz) with ± 12dB range and Sweepable Midrange Bell EQ (100 Hz to 1 kHz) or (1 to 10 kHz) with ±10dB range. The limiter features a fast-attack FET brickwall limiter, continuously variable Threshold and Release controls, Peak Limit LED indicator and 10dB range output gain control.
