The inventors of the 500-series format

API (Automated Processes, Inc.) has been building discrete Class-A console electronics in the USA since 1968 and created the 500-series rack format that much of the industry still builds around today. The lineup ranges from the iconic 512c mic preamp and 550 series EQs to the 2500+ stereo bus compressor and complete lunchbox racks.
