API Select SR24 Dual-channel Parametic Equalizer

Workhorse Parametric EQ with a Classic Pedigree

The API Select SR24 is a dual-channel workhorse parametric EQ with a storied lineage. Its circuitry is based on the APSI 562, which was designed and manufactured by a small audio company called APSI and distributed by API. Though APSI was a relatively minor player in the pro audio world, their 562 EQ became a favorite of many top studio engineers for its simplicity and versatility. With the SR24, API has faithfully updated this beloved EQ and re-engineered it for enhanced performance. What’s more, the SR24 packs two fully parametric EQs into a single 2U chassis — ideal for crowded racks and project studios. Four bands of continuously variable equalization are on deck, giving you precise control over a 20Hz to 20kHz range with +/-12dB of boost and cut on each band. Surgical and transparent, the SR24 is a go-to EQ when you need to shape the tone of a signal without imparting additional character. On top of that, the SR24 delivers the quality you would expect from API at a price that won’t break the bank!

API: an American pro audio legend

Launched in 1968 by Saul Walker, Automated Processes Inc. began building high-quality consoles for broadcast applications. Soon, the company’s products found favor with recording studios, and a string of industry-leading innovations (including the 500 Series module, the first VCA, computerized console automation, and more) followed. API produced the 2520 amplifier, one of the most famous op-amps in the recording industry, and their consoles and products found homes in such iconic studio facilities as the Hit Factory, Record Plant, Ocean Way, Sunset Sound, and many others. In fact, there are over 700 vintage API consoles around the globe — many of which are still in use. Clearly, the company isn’t resting on its laurels; today’s API and API Select products give you the same unbeatable combination of utility, innovation, and stellar sound. That’s why, at Sweetwater, the name API commands reverence.
