Brazil (August 13, 2020) — Rádio Itatiaia, a Brazilian broadcaster with a network of 52 affiliate stations in the state of Minas Gerais, has installed a new Lawo routing system to switch, process and distribute programming from its headquarters in Belo Horizonte.
Project planning began in 2018, with the goal of replacing an aging digital router with a AES67 system that could work with AoIP equipment from a variety of manufacturers and be expanded to accommodate future needs. Rádio 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.
Lawo integration partner Rádio Partes installed the new system, which features Power Core mixing engines, Nova17 routing frames and custom touchscreen controls designed with Lawo VisTool Unlimited graphical control software.
All Lawo radio products employ AES67-compliant Ravenna networking, enabling accommodation of Itatiaia’s array of AoIP, analog and digital audio sources. The system’s redundant routing core utilizes two Lawo Power Core engines, each of which is paired with a Nova17 routing frame equipped with dual, redundant mastercards. These, in turn, are interconnected via mirrored MADI backbones, with automatic failover from the primary to the secondary system in the event of a fault.
Control is redundant as well: physical controls via rack-mounted KSC key panels, and touchscreen PCs with VisTool graphical control software. All hardware power supplies are redundant as well. A PTP grandmaster synchronizes everything, with a Lawo A__mic8 unit providing backup clocking. Routing control is handled from a central control room whose racks contain the routing core equipment.
“There are several factors that make this project truly unique,” says Cláudio Carneiro, Rádio Itatiaia’s vice president. “The ability to integrate with our existing AoIP mixing desks as well as Dante devices using Ravenna with AES67 is unprecedented. Other things that won us over were the ability to operate the system using both touchscreens and dedicated key panels, and the system’s complete redundancy.”
