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; by utilizing continuously variable controls for frequency and boost/cut, the SR24 can be very precise in applying equalization to 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 mixing consoles and equalizers. Their 562 module was a fully parametric four-band equalizer designed by APSI and sold by API. Over the past few decades, these equalization modules have remained favorites of many studio engineers but have become increasingly difficult to find. The SR24 is a faithfully reworked version of the original 562, offering the user two channels of classic analog equalization in a rack-mountable unit.
