Installation Case

Intec Systems recently completed major upgrades to the audio systems of two of New Zealand’s largest churches. Both installations were required to be easily re-configured depending on the requirements of each service with Dante providing the ideal connectivity solution.

Installation Case

Now in its 17th year, Italy’s La Notte della Taranta (Night of Tarantula) is both the country’s biggest music festival and its most important event dedicated to traditional culture. Three weeks of live concerts culminated in a huge show in the town of Melpignano, where four Yamaha CL and QL consoles weaved ancient and modern music seamlessly together.
