The Tosca Opera took place outdoors on a massive open air stage in Masada, a solitary plateau in the Judean Desert. The temperature was about 54-degrees Celsius. Clear-Com’s FreeSpeak II 1.9GHz was used for production communication. Even under extreme heat and an open environment in the middle of nowhere, FreeSpeak II worked perfectly and the audio quality was clear. The director and stage crew were truly impressed with the system and gave FreeSpeak II glowing remarks. Watch the video!
