Equalisers

Equalisers are fundamental signal processing tools used to shape tonal balance in recording, mixing and mastering. From early passive and valve designs to discrete transistor and integrated circuit based circuits, hardware equalisers have defined the frequency character of countless recordings.

This archive includes vintage studio equalisers alongside modern hardware designs and recreations of classic circuits. From broad program equalisers to fully parametric systems, these processors remain central to professional studio workflows and analogue production techniques.
