Czech Radio uses Lawo Nova73 and DALLIS technology for 6 years and the time has shown that this robust, thinked-through, in all aspects redundant set of devices was a lucky choice for the mission-critical role of central routing of over 20 radio stations, all being 24/7 on-air.
By the end of 2020 and in 2021 we delivered hardware expansion to Czech Radio to provide even more redundancy for possible emergency situations. To introduce RAVENNA / AES67 / SMPTE ST2110 networking capabilities of the Lawo hardware an important firmware upgrade was necessary. This was carefully prepared, executed and monitored overnight - all of that in tight cooperation with Czech Radio and a skilled Lawo engineer.
The unique redundant hot spare + cold spare router architecture is enabled by the control and monitoring system VSM by Lawo which was also upgraded to reflect the latest features including the favorite Panel Inheritance.
