Project: Emanu-El Synagogue

Product: ListenRF

San Francisco’s Congregation Emanu-El had its temple’s membership in mind with the recent installation of next generation of assistive listening products from Listen Technologies. iDSP, or Intelligent Digital Signal Processing, revolutionizes the assistive listening experience. Martinez, California-based firm Pro Media / UltraSound – a leading professional A/V integrator specializing in installations as varied as Levi’s Stadium [the home of the 49ers], the deYoung Museum, the Santa Clara Convention Center, the San Francisco Opera House, corporate and worship facilities of all sizes, and others – worked closely with Listen Technologies personnel on the project, completed in time for the High Holy Days.

The systems were integrated in both the synagogue’s main sanctuary and smaller Martin Meyer Auditorium. Pro Media/ UltraSound Project Lead, Patrick Waller explains how this installation came about: “Emanu-El has a number of elderly congregants and others with hearing loss or impairment. There were some assistive listening systems in place, but they weren’t compatible with certain hearing aids, or were just not effective for some members. Judi Leff, Director of Projects and Programming at Emanue-El, is a longtime customer and friend of ours, and she contacted me about upgrading their assistive listening tools; we explored a number of options. Products from Listen Technologies immediately came to mind, but some of our ideas were not feasible right away, because the space’s marble floors prevent wiring/looping techniques. Listen Technologies let us know about their iDSP products, everything clicked into place for the project, and we were able to move forward immediately. Everyone at Listen Technologies was so helpful during the planning process, and the installation was seamless and efficient.”

Pro Media/UltraSound installed and commissioned the system quickly, to have everything in place in time for Rosh Hashanah and Yom Kippur services, which are two of the most well-attended services of the worship year.
