Pulse Techniques EQP-1S - Pultec EQP-1S Program Equalizer The Pulse Techniques EQP-1S is a mono valve EQ. This unit features the same wide-bandwidth line-amp as the EQP-1A/EQP-1A3 but has modified low-frequency boost/atten response curves, 2 additional peak boost frequencies and most-importantly 2 additional high-frequency shelf boost curves. The EQP-1S is a truly musical program EQ. In 2014, due to customer demand, Pulse Techniques brought back into production the 3U EQP-1A program EQ. Many of our clients prefer the look and layout of the larger unit to that of the 2U EQP-1A3 and the EQP-1A has become one of our most popular units. Almost immediately after announcing the return of the EQP-1A, we started receiving requests for the EQP-1S, the 3U version of the EQP-1S3.
