Electrosonic Multimedia Appeasement Exhibit, The Museum of Tolerance


Electrosonic, an international audio-visual company that creates tailored, state-of-the-art solutions, has designed and installed the new Appeasement Exhibit for The Museum of Tolerance, Los Angeles.

The multimedia exhibit explores Hitler’s rise to power against the backdrop of the pre-World War II political landscape with letters, archival footage, speeches and interactives.  

The Appeasement exhibit’s focal point is a giant relief map of Europe, spanning a curved wall, with touch monitors.

“A Panasonic PT-DZ870LK ultra-short throw projector makes the map come alive with video images of the war’s progression as it highlights how territories and borders morphed when World War II got underway and armies advanced, ” explains Electrosonic project manager Steve Calver.

“Videos pop up and go away, arrows move, armies march – the display is constantly dynamic.  With the ultra-short-throw projector, you get a large projected image that people can stand much closer to than with traditional projection lenses without interfering with the projection envelope and creating shadows. In this specific application, the projector was a less expensive and more aesthetically appealing choice when compared to a custom surface mounted LED wall.”

Every visitor to the museum receives a photo passport card on entry which tells the story of a person who was affected by the Holocaust.   Additional information is provided at a station inside the museum and visitors receive a printout at the final station before leaving.  Electrosonic also replaced all 24 of the museum’s card reader CRT monitors with new 21.5-inch NEC LCD monitors.

Electrosonic completed the project in a tight time frame.  Some of the work, for example adding hardward and programming had to be completed without disrupting other exhibits while the museum was open to the public.

Key technical features and partners for the exhibit include:

  • A 7thSense server warps the images onto the map (covered with a slightly reflective projection surface) which was created by Cortina Productions. 
  • A Dakota Audio ceiling speaker, mounted above the map, provides a narrowly directed audio field.
  • A single Planar 70-inch multi-touch monitor with headphones enables up to four visitors to drill down and learn more about the subject.  
  • NLE computers drive the interactive content.
  • Chief mounts were used for the 70-inch Planar monitor and the new NEC LCD monitors. 
  • BrightSign players and Extron extenders were also used.
  • Yazdani Studio of CannonDesign was the architect. 
  • Cortina Productions was the film and interactives producer. 
  • Coastal was the general contractor for the new exhibit.
  • The museum has a service contract with Electronic for technical maintenance.
