Pultec hat 1951 den ersten passiven EQ, namens “EQP-1″ eingeführt. Der EQP ist das Vorzeigeprodukt der Firma, bis zu ihrem Ende in den späten 70ern/frühen 80ern, gewesen.
The original EQP-1A program Equalizer
Founders Ollie Summerland and Gene Shank (no, not a family relation to me) made up the famous two-man operation of Pultec (the formal name being Pulse Techniques Inc.), who made every item to order, all by hand. The two men comprised the engineering, marketing, sales and production staff for the entire history of the company! The Pultec storefront was located in Teaneck, New Jersey (although the formal address was West Englewood, NJ), the same town where Les Paul built his first “home studio” and incorporated the first eight-track recorder.
An interesting note in the Pultec design legacy, the passive EQ circuit designs were licensed from Western Electric. Pultec combined the passive design with a tube gain make amp to overcome the typical 16 dB insertion loss of a passive equalizer. So this made the Pultec appear to be “lossless.”

The build quality and design of all the Pultec products was unparalleled. A testimony to this is the numerous working units still available in the audio production world. It is said the men were very secretive about their designs, and very few were ever allowed to visit the facility. In addition to the famous tube EQ’s, Pultec also made solid-state versions of these units, which were the silver-face variety. Perhaps less known, Pultec made filters, small mixers and preamps, one of the most intriguing products being the MAVEC, an early “channel strip” that included a mic-pre, eq, and simple compression all in a 2U rack mount design.
