For 50 years, RTW from Cologne has accompanied the steady technological progress in the pro-audio industry with innovative instruments and technologies for visual audio monitoring in broadcast, production, post-production, and quality control. Whether audio metering, loudness metering, or signal monitoring, RTW’s state-of-the-art systems are the result of a future-oriented strategic approach that focuses on continuous development while putting maximum attention to reliability and protecting their clients investments. 

In 1965, RTW was founded as a specialist service provider for audio equipment. During the following years, the company became a dedicated audio-systems developer and a key vendor of professional broadcast and audio-metering equipment. Andreas Tweitmann took over RTW in 2007 and is now CEO of the company. 

From the RTW Peakmeter featuring the famous gas plasma tube that started RTW’s overwhelming success in radio and TV studios all over the world in the 1970ies to the TouchMonitor range incorporating a top-notch loudness system, RTW has again and again succeeded in setting new standards in terms of perfection and precision for the entire industry. Milestone products include the internationally acclaimed Surround Sound Analyzer providing intuitive surround visualization as well as the SurroundControl 31900/31960 featuring an integrated monitoring controller, a 3G SDI de-embedder, and a Dolby® decoder for seamless integration into the production workflows of modern broadcasting and TV studios. 

RTW has been certified by TÜV Rheinland Cert GmbH to comply with the international ISO 9001:2008 quality-management standard. In 2010, RTW went through a strategic renewal to position the company as a highly experienced leading vendor who meets its customers’ requirements with innovative made-to-measure solutions and state-of-the-art systems.
