The company was originally founded in Zürich in 1948 by Willi Studer (de). where it quickly became famous for its high-quality tape recorders.
Willi Studer started in 1948 making high-tension oscilloscopes, but in 1949 branched out into audio by modifying imported tape recorders from the USA. By 1950 they had developed their own line of tape recorders, named the Dynavox series. Oscilloscopes remained part of their product line-up until 1968.
STUDER's analog tape recorders were widely considered to be the best in the world by audio engineers due to their excellent reliability and sound quality. The company has built a variety of two-track recorder models throughout its history for stereo recording and mixing. One of the company's most successful models was the Studer-Revox A77 recorder, which was introduced in 1967. It sold over 400,000 units.
STUDER was also an innovator in the design and production of multitrack recorders. The model J37 four-track recorder was used to record the Beatles' renowned Sgt. Pepper album in 1967. Later Studer multitrack recorders were built in 8-, 16-, and 24-track configurations. With the addition of SMPTE time code multiple machines could also be linked together, making the number of available tracks virtually unlimited. Sales of these analog machines continued to be strong into the early 1990s when they began to be replaced by digital recorders.
In 1994 STUDER became part of Harman International Industries joining other word-class brands such as AKG, BSS, Crown, dbx, Lexicon, Martin, JBL and Soundcraft. The founder, Dr. Willi Studer, died on March 1, 1996.
