From our Who’s Buying What page comes this look into a new Lawo installation for Brazilian broadcaster Rádio Itatiaia.
The supplier says the broadcaster installed a new routing system to switch, process and distribute programming from its headquarters in Belo Horizonte. Rádio Itatiaia supports a network of 52 affiliate stations in the state of Minas Gerais.
The new system uses Lawo’s Power Core mixing engines, Nova17 routing frames and custom touchscreen controls that were designed with Lawo VisTool Unlimited graphical control software. Rádio Partes did the integration.
“Project planning began in 2018, with the goal of replacing an aging digital router with a true AES67 system that could work with AoIP equipment from a variety of manufacturers, and be easily expanded to accommodate future needs,” Lawo stated in a press release. The system uses the Ravenna networking protocol.
“Itatiaia also wanted a system with DSP capabilities to enable audio shaping of sources on-the-fly, and, being a network content provider, operational redundancy at every level.”
Redundancy is provided by two Lawo Power Core engines, each paired with a Nova17 routing frame with dual redundant master control/interface cards that are interconnected via mirrored MADI backbones, with automatic failover from the primary to the secondary system in case of a fault. Control also is redundant, with physical controls via rack-mounted KSC controller panels and then touchscreen PCs with VisTool graphical control software.
A PTP grand master handles synchronization, with a Lawo A__mic8 unit providing backup clocking.
Rádio Itatiaia’s Vice President Cláudio Carneiro was quoted in the announcement saying, “The ability to integrate with our existing AoIP mixing desks as well as Dante devices using Ravenna with AES67 is unprecedented.”
Lawo posted a case study on the Rádio Itatiaia project at its website.
