Profile: Lexicon is an American company that engineers, manufactures and markets audio equipment as a brand of Harman International Industries (HII), with offices in Salt Lake City. Originally founded in 1971 and headquartered in Waltham, Mass., the company was acquired by HII in 1993.

Lexicon traces its history to the 1969 founding of American Data Sciences by MIT professor Dr. Francis F. Lee and engineer Chuck Bagnaschi, developers of digital audio devices for medical heart monitoring.

The company is widely known as the OEM developer of the multi-speaker audio system for the Rolls-Royce Phantom — as well as the Hyundai Genesis, Hyundai Equus and Kia K900.

Lexicon is sometimes credited as the inventor of commercial digital delay products. The first product to market was the popular Delta T-101 delay in 1971, followed by the Delta T-102 in 1972.

Lexicon is considered "the godfather of digital reverb", as one of the early players on the reverb/reverberation market. The company was among the first to produce commercially available digital reverb equipment, beginning in 1978 with the Model 224. In 1986, Lexicon released the 480L (costing more than some cars), a successor of the 224XL. Show less
