American DJ ADJ DS4QC1 Design Series DS4 Top Left Quarter Circle LED Video Panel

The DS4QC1 is the top-left quarter-circle panel in the ADJ Design Series modular video system. It carries a 4.8mm pixel pitch, 104 x 104 pixels per panel, and 1200 NITS of brightness from 3-in-1 SMD2020 LEDs, so it reads well under stage lighting from a minimum viewing distance of 12.5 feet. Because the Design Series mixes square (DS4), triangle (DS4T), quarter-circle (DS4QC), and rectangular (DS4HC) panels on shared rigging and data, this piece rounds off a corner of a screen or builds curved and circular shapes a square-only wall cannot. Viewing angles run 160 degrees horizontal and 120 degrees vertical, which keeps the image readable for audiences off to the side. Processing is 14-bit with a 1920Hz refresh rate and brightness adjustable across 100 levels, and control runs through a Nova Star synchronous system over DVI, with composite, S-Video, component, VGA, HDMI, and HD-SDI inputs supported. PowerCon in/out and EtherCon in/out chain power and data between panels, with control distance up to 100m over Ethernet cable or beyond 120m on fiber. Each panel weighs 14 lb, measures 20 x 20 x 3 inches, and draws 52.5W on average and 157.5W maximum, for touring productions and fixed installations alike.
