Key Workflow: Guarantee ultra-low latency and perfect signal integrity in mission critical applications for broadcast automation and on-air, video and post production
The LX-MADI sound card performs ultra-stable 24/7 record/play operations with sub-millisecond round trip latency on its PCI Express interface. Its hardware-based architecture maintains performance regardless of the computational load of other applications running on the host system. This guarantees continuous quality of service in all demanding broadcast automation and on-air, video and post production workflows.
