![]() ![]() The amplifier circuitry was originally licensed from Western Electric (the manufacturing arm of AT&T from 1881 until 1995).įollowing the demise of Pultec, original units have become highly prized. Pultec’s passive EQ was combined with a valve gain make up circuit to bring the level back up by the 16dB or so caused by insertion loss. The original EQ design remained largely unchanged during that entire period, and units were all hand built by the pair. ![]() Developed at the beginning of the 1950s in New Jersey, the Pultec company’s formal name was Pulse Technologies, the operation run entirely by Ollie Summerland and Eugene Shank until the company folded in the late 1970s. (This pair of units, was one of the first units and had the front panels with original name brand, which are currently replaced by name “ProReplicas”.Surely the audio industry’s most copied product, in hardware and latterly in software, is the Pultec EQP-1A Program Equalizer. This is one snapshot from whole article in Attack Magazine. Independent review about units EQP-1A from ProReplicas. 5, 10, 20 kHz: Shelf attenuate, 0 to 16 dB.This is the perfect device for the processing of the individual traces but also the whole mix so it can be used successfully in the work of mastering. All this gives a very smooth, almost velvety sound. EQP-1A has been and still is used in major recording studios because of the exceptionally natural equalisation for highest and lowest frequencies and unique sound, arising from the use in the signal path three audio transformers, coils in the filter high frequencies and the output amplifier based on two classic tubes. All family of original Pultec EQs, was originally designed to bring back the life and musicality lost in a recording. This equalizer is still unsurpassed device model for treatment frequency in recordings among audio engineers worldwide. The Pultec EQP-1A is a tube program equalizer designed via Eugene Shenk in 1951 year. ![]()
