Power Over Ethernet enabled Ethernet switch or Power Injector The LSS 100P should be mounted on the rear wall of the auditorium It is aimed towards the center of the screen using the internal LEDs Before the first show or after the last show a test pattern is projected and pink noise sent to each speaker The LSS 100P measures the color luminance and SPL These measurements are used to identify lamps nearing end of life misadjusted lamps projector color problems defective speakers etc Since measurements vary in different positions in the room the measurements from the LSS 100P should be compared with previous measurements to detect changes rather than interpreting the absolute values delivered by the LSS 100P LSS 100P Package Contents 1 LSS 100P Unit 1 Power Supply USB Charger 1 Power Cable 30 USB 1 Wall Ceiling Mount 1 USB To Terminal Adapter 1 LSS 100P User Manual LSS 100P Installation amp Operation Manual Features e Luminance Measurement Uses a precision detector with a photopic spectral response e Chromaticity Measurement Uses a precision RGB sensor and calculates XYZ xy and CCT e SPL Measurement Uses a DSP generated C weighting filter and RMS detector for accurate results regardless of signal waveform or crest factor e IR Measurement Measures relative IR illumination of screen to detect issues with IR emitters used for hearing impaired audio visually impaired
