Germany’s Fresenius University Uses TouchLink for User-Friendly AV Control
The Fresenius University of Applied Sciences in Germany boasts a 160-year tradition of science education. When the university decided to update the AV system in a media room at its Cologne campus, it hired AV integrator, Mertens AG to install the new system, with equipment and design help from Extron Electronics.

The university wanted its AV system to facilitate interactive dialogue between students and teachers, and to simplify the connection of modern media sources to the media room’s new displays and speakers. According to Mertens AV Engineer Dirk Blotevogel, “Teachers and students were bringing in their own personal devices. The existing AV system was outdated and couldn’t support the newer sources, in addition to the PC, wireless microphones, and Apple TV already in the media room.”
Blotevogel says that his biggest challenge was user acceptance. “The system had to be simple and user-friendly enough to overcome teachers’ objections to new, unfamiliar technology,” he says. “We were very happy to learn that we could deliver an easy to use system that met all the teachers' needs within our planned budget.”

An RGB-HDMI 300 A Stereo Audio to HDMI Scaler connects legacy analog sources to an Extron DXP 84 HDMI Matrix Switcher. In addition to HDMI and DVI, the matrix switcher provides high performance routing of the digitized and scaled signals. Two Extron technologies, EDID Minder® and Key Minder®, helped simplify integration. EDID Minder ensures all sources power up properly and reliably output content for display. For encrypted content, Key Minder authenticates and maintains HDCP encryption between devices to ensure quick and reliable switching.
The media room is equipped with a microphone for the instructor, so the system benefits from the inclusion

The university’s new AV system meets both the school’s and the teachers’ needs. “Thanks to the easy-to-use TouchLink touchpanel, teachers are very comfortable using the system,” Blotevogel says. Just as importantly, the system efficiently routes signals from the latest AV sources to the latest displays and speakers, creating a fully collaborative learning environment.
