Management, sales, engineering, R&D and customer service were based in Regensdorf, Switzerland, until owners Harman International Industries closed down the Swiss entity in March 2018 transferring the now decentralized operation to China, Hungary, and the US.

The extensive reorganization culminated in the sale of the Studer group to Harman International Industries in March 1994.

In 2006 Harman closed all of the original headquarters of the brands in its professional division portfolio and moved Studer support and manufacturing to Pécs, Hungary to cut costs.

In 1949, Studer branched out into the audio business by modifying imported tape recorders from Ampex in the United States.

Some Studer model variations were sold under the Revox name, with slight modifications, at a lower price.

The Revox variants were designed for consumer use, with features such as IR remote control, and the omission of balanced input/output sockets.

In this period, Studer introduced the D820 and D827 multitrack models, which employed the Digital Audio Stationary Head standard.

However, digital tape formats eventually fell out of favor with the introduction of computerized hard disk drive recording systems and software products such as Pro Tools.

A Studer A800 MKIII is the focus of the opening shot of the video for the 1988 Guns N' Roses song "Patience".

After introduction of OnAir 2000 with Touch'n Action user interface in 1997, the D950 was the first digital large frame desk Studer introduced in 1998.
