API Audio Story Banner

The API Audio history is something of legend in the pro audio market. It is considered the pinnacle of high end recording equipment for sound engineers. API Stands for Automated Processes, Inc. and was founded by audio engineers and music professionals in 1968. Today API Audio is well known for their classic pro audio tools - their preamps, compressors and EQ's are a staple in every professional audio recording studio facility. Their studio outboard gear is among the best in the business and feature on many recordings. API pioneered the use of the modular, portable "lunchbox" design where you can add 500 series modules into a chassis that provides the power. The 500 series format is now the standard and many other outboard manufacturers make units to fit this design.
