Both courses will be hosted at multiple locations across the US, including at the Renkus-Heinz factory in California. The senior course instructor is well-known pro audio developer, instructor, AES moderator, author and journalist John Murray.
Worth four RU credits, the Intelligibility (Non-Manufacturer) course covers Line-Source vs Point-Source, Technology Theory and Intelligibility. Topics include understanding line-source versus point-source behaviour and their fundamental characteristics; understanding STI (Speech transmission Index) and how it can be used to assess a sound system’s intelligibility; and understanding the relationship between high-Q line-array directivity and the resulting intelligibility in difficult acoustic spaces.
The Manufacturer course (worth two RU credits) is the Renkus-Heinz Iconyx Certification Course, which covers creating a network of Iconyx steerable line arrays with a TCP/IP control interface via a laptop computer; optimising an Iconyx steerable line array system via active beam steering for maximum evenness of coverage; and using EaseRa SysTune to equalise an Iconyx array and assess its intelligibility using STI.
‘We are very pleased to offer these new RU courses to audio professionals throughout the country, especially with the high caliber of instruction that delivers each course,’ says Renkus-Heinz Marketing Manager, Margie Ulm.
