Api SR24

The SR24 is a two-channel, four-band equalizer in a two-slot chassis.

With a dedicated knob and/or switch for each control function, the SR24 is easy to use; using continuously variable controls for frequency and boost/cut, the SR24 can be very precise in applying equalization to the selected audio material.

The SR24's circuit design is deeply rooted in API's history. From the late 1970s to the early 1980s, an audio company called "APSI" manufactured consoles and equalizers. Their 562 module was a fully parametric 4-band equalizer designed by APSI and sold by API.

Over the last few decades, these EQ modules have remained a favorite of many studio engineers, but have become increasingly difficult to find.

The SR24 is a faithfully re-engineered version of the original 562, offering the user 2 channels of classic analog EQ in a rack-mount unit.
