API Select SR24 Dual-Channel Equalizer

The API Select SR24 is a two-channel, four-band equalizer in a two rack-space chassis with a dedicated knob and/or switch for each control function. By utilizing continuously variable controls for both the frequency and boost/cut, the SR24 can be very precise in applying equalization to the selected audio material. From the late 1970s to the early 1980s, an audio company called “APSI�?manufactured consoles and equalizers. Their 562 module was a four-band, fully parametric equalizer which was designed by APSI and sold through API. Over the last several decades, these EQ modules remained a favorite among 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 two channels of classic analog EQ in one rackmount unit.
