by Simon Byrne. THE LIVE PRODUCTION AND PRESENTATION INDUSTRY RELIES ON EXTREMELY RELIABLE DATA NETWORKS TO DELIVER OUR SOUND, LIGHTING AND VISION CONTENT. THE DAYS OF LARGE ANALOGUE (AND HEAVY) MULTICORES ARE GONE. THIS CAN BE SCARY FOR THOSE OF US WHO HAVE BEEN AROUND FOR A WHILE. THE CONCEPT OF TRANSPORTING ALL OF OUR […]

In the late 1980s they cost about $180,000 and produced a massive 1,500 lumens! Yes, a $180,000, 75 kilogram machine produced less light output than your cheapest office LCD projector that you’d pickup from Officeworks […]
