The Sony LKRI-003 is a vital component for integrating professional broadcast and video production equipment with high-end Sony installation projectors (such as the SRX series). This input board fits into a dedicated option slot on the projector chassis and adds two BNC connectors for accepting both standard definition (SD-SDI) and high-definition (HD-SDI) signals. The "Dual Link" functionality allows the projector to receive very high bandwidth or specialized signals over two cables simultaneously, ensuring uncompromised signal integrity and performance for critical viewing applications in command centers, simulators, post-production houses, and broadcast facilities. It supports various frame rates and formats, automatically detecting the incoming signal.
