UAD Powered Plug-Ins Manual - 395 - Chapter 39: Pultec Passive EQ Collection
History
In 1951, Pulse Techniques introduced the first passive Program Equalizer, the
EQP-1. The passive EQ filter designs were originally licensed from Western
Electric. Founders Ollie Summerland and Gene Shenk made up the Teaneck,
New Jersey operation of Pultec. These two men comprised the engineering,
marketing, sales and production staff for the entire history of the company,
and made every item to order, all by hand. With the EQP-1A, Pultec im-
proved the original design with tube amplification to overcome the typical in-
sertion loss of passive equalizers. The EQP family of EQs would see many it-
erations, but the fundamental design would be Pultec’s flagship product until
the company’s closure in the early 80s.
