Automated Processes Inc. (API), best known for their now legendary "2520 amplifier," formed in 1968 and continues to use the 2520 op-amp as the cornerstone of all API discrete products. The resulting console meets the needs of the music, commercial and broadcast industries, positioning API as the leading audio broadcast console manufacturer for audio production outfits of any sort. There are now over 700 API consoles around the world, including one at WNYC 93.9 FM, New York City’s premier public radio station. In 2009, Vintage King Audio worked with WNYC on the acquisition and installation of an API Legacy Console in the station’s revolutionary Greene Performance Space. API has also led the way in modular outboard technology with their VPR 500 Series products. Offering their own 512c mic pre, 525 compressor and 550a, 550b and 560 equalizers as the kingpins of the format, these units are fully interchangeable within any 500 Series compatible rack structure, supplying power and input/output connections directly to the modules. Several manufacturers today build modules and racks that are fully compatible with this versatile modular system.
