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 well-known Bosch quality standards to RTS through streamlined and modernized processes, as well as a renewed commitment to research and development.
