LAWO Nova73 HD Router

Anyone who chooses a Nova73 HD has clearly decided for cutting-edge technology, absolute serviceability and an easy-to-operate user interface. The HD technology offers everything you would expect from a modern router — 96kHz operation, Dolby-E compatibility, and clock-synchronised switching to video frames or internal DSP. But what makes the Nova73 HD really special is that all its features are deliberately designed to be easy to use — an enormous advantage both in day-to-day operation, during installation and maintenance.

In terms of performance, what makes Nova73 HD so persuasive is its massive potential of up to 8,192 inputs/outputs, available via RAVENNA, AES3, MADI and SDH/STM-1interfaces but all in a compact 10U package. In terms of configuration and user friendliness, Nova73 HD features a hot-plug capability and online configuration that even allows you to expand and change the system during live broadcasts. In terms of security, Lawo’s STAR² technology provides maximum redundancy and fail-safe operation. When it comes to performance and reliability, all the facts speak in favour of Nova73 HD.

More advantages:

  • Flexible modular platform, scalable up to 8,192 mono channels
  • Enormous interface versatility via I/O system DALLIS with fibre-optic infrastructure and with direct ATM/SDH connection
  • Easy maintenance management thanks to a graphic interface and the possibility of on-air configuration
  • Unique Dual Self-Healing Star topology possible
