The money has been spent on a Grass Valley 4 M/E (mix/effects) Kayak mixing desk and a Calrec Zeta sound console, talkback matrix and monitor stack.
The Kayak will make more cameras and VT machines available for live playout and offer improved graphics capability.
It is switchable between HD and SD which, according to Roll to Record managing director Steve Jenkins, will make it “futureproof”.
Jenkins added: “Big Brother is incredibly demanding in terms of technical innovation, it is imperative that we keep offering and advancing our infrastructure.”
Roll to Record will continue to use its robotic camera heads to watch the housemates over the 53,235 crew hours that make up the series, which started on 10 June on Channel 4.
