In the early days of television production, intercommunication among the crew was accomplished using carbon microphone conference line intercom systems. These systems used telephone company equipment and telephone company technology. This technology was not intended to conference more than two stations, and television production needed as many as 30 stations to conference together. As the number of stations ranged from 10 upwards, the performance of the system was severely degraded. Some improvements were made over the years, but the system’s flaws were never fully addressed.

In 1975, the founders of RTS took a systems approach to solve the fundamental system design problem. After six months of intensive work, the problem was solved, and products were developed to utilise the solution. This first solution was called the “Two-Wire Intercom System”. The company formed then, to solve the problem and to market the solution, was—and still is RTS Systems.

From 1979 to 1989, RTS’ products became a standard for the television industry. The major television networks incorporated RTS Systems products. In addition, RTS Systems products became the standard for mobile units.

In 1989 Telex Communications, Inc. bought RTS Systems and a new growth period began. This growth included improvements in manufacturing efficiency, a strengthened sales organisation, and an advance in manufacturing technology (surface-mount circuitry, plastics moulding and tooling resources). In 1989 RTS won an Emmy award for Outstanding Achievement in Engineering Development in recognition of their engineering contribution and development of professional two-wire intercommunications systems for use in television production and broadcast operations.

In 1990, Telex acquired the exclusive manufacturing rights to the McCurdy line of matrix intercoms to complement the series of party line intercoms already manufactured by RTS. In the 1940’s, McCurdy Radio Industries of Canada began manufacturing intercom systems and in the mid 1970’s introduced a solid-state intercom matrix called the 9100. Upon acquiring the line of matrix intercoms from McCurdy Radio, Telex started to extend and improve its product portfolio. Since the RTS brand name was well known in the broadcast market, the new digital matrix products were branded RTS, as well.

In September 2006, RTS became a part of The Bosch Group. The acquisition brings the Bosch quality standards to RTS through streamlined and modernised processes, as well as a renewed commitment to research and development.
