The LSS-200 is designed for cinema auditorium quality control. It measures C-weighted sound pressure level (SPL) in dB, luminance in cd/m2 and fL, chromaticity (x and y), correlated color temperature, and audio/video synchronization. The LSS-200 makes all of these measurements available on a web interface, through TCP commands over Ethernet, and by posting data to a remote web server for further analysis and display.
