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 its 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 products give you the same unbeatable combination of utility, innovation, and stellar sound. That’s why, at Sweetwater, the name API commands reverence.
