Pultec EQP-500X 500 Series program EQ
EQP-500X EQ combines the best features of its EQP-500A and EQP-500S EQs.
Modeled directly after the rack-mount EQP-1A3-SS solid-state program equalizer, the Pultec EQP-500A is the exact same unit ported for the 500 Series form factor.
In the early 1970s, after condensing the classic 3U model EQP-1A into
the 2U form-factor model EQP-1A3 (with the exact same components and
specs), Pulse Techniques introduced a solid-state line amp version of
the EQP-1A3. This version, based on the venerable API 2520 op-amp, is
preferred by some engineers for certain applications, such as kick and
bass. Pulse Techniques has taken this proven design to the next stage by
packing them into the 500 Series form factor. These EQs deliver all of
the punch and mojo of their full-sized counterparts.
