Manley PEQB Enhanced Pultec EQ / Equalizer

Manley PEQB Enhanced Pultec EQ / Equalizer

The Manley PEQB is the Enhanced Pultec EQP1-A Equalizer made by Manley Labs that is a professionally designed modern version of the single-channel, two-band classic Pulse Technique EQ that comes featuring a low and high frequency control, each comes along with simultaneous boost and cut capabilities. Professional-grade components are used throughout and comes including an conductive plastic potentiometers, sealed gold-contact switches, foil capacitors, polystyrene capacitors, rolled film capacitors, custom-wound transformers and a B+ power supply that comes along with regulated and balanced heater supply. The all-tube make-up gain block is used for amplifying the passive inductor-based circuit providing high output and low distortion.

The Enhanced Pultec is made divided up into three sections. Low frequency is capable of offering a shelf-style filter that comes along with frequency selection, boost and cut, and at the same time the high frequency boost is a peak filter featuring a variable bandwidth control, frequency selection and boost control. The high frequency cut is offering a shelf filter that comes along with frequency selection and cut control. Which utilizes both cut and boost controls simultaneously that's resulting in unique shapes for custom tailoring your sound.

Features not found in the original design include an expanded frequency selection, transformerless inputs and outputs, and a gain set preset for adjusting the feedback over the line amplifier. The 3-way toggle switch on the rear of the unit provides phase reversal. The up position retains 0°, while the down position switches the balanced transformer wiring 180° out of phase. The center position switches off the transformer, optimizing the unbalanced 1/4" input to an impedance of 5000Ω. Handmade in the USA, the unit is housed in a 1U steel chassis with a CNC-machined 1/4" faceplate that is also inlaid with laser-engraved inserts. The Enhanced Pultec ships with an IEC power cable.
