From the genesis of this project, we have insisted on one thing:  “Unless we can faithfully reproduce the
original design, we will not proceed with a product.”  Years later, we have achieved our goal and
the Pulse Techniques EQP-1A3 is produced to the same specifications as the original EQP-1A3,
with the minor exceptions of XLR input and output connectors and an IEC modular power connector.
