The Extron SW HD 4K are two and four input switchers for HDMI signals. They are designed for video signal switching between multiple HDMI source devices to a single display. The switchers support video signals at resolutions up to 4K, as well as data rates up to 10.2 Gbps, 3D, Lip Sync, and HD lossless audio formats. Both models feature EDID Minder®, which maintains continuous EDID communication with connected devices and ensures that the HDMI sources power up properly and maintain correct video output. The switchers provide automatic input cable equalization up to 50 feet on Extron HDMI Pro Series cable. The SW HD 4K switchers offer front panel, RS?232, IR, contact closure, and auto-input switching control options for integration into a wide variety of environments. To enhance and simplify integration, the SW HD 4K switchers provide integrator-friendly features, including automatic input cable equalization, automatic color bit depth management, indicators for monitoring and troubleshooting, as well as peripheral device power on each output. Automatic input cable equalization corrects for signal loss due to lengthy input cables, ensuring signal integrity up to 50 feet,when used with Extron HDMI Pro Series cable. The switchers automatically adjust color bit depth based on the display EDID to prevent color compatibility conflicts between source and display. Front panel LED indicators provide immediate visual confirmation of HDCP authentication and signal presence for each input and the output. If HDCP?encrypted content is transmitted to a non?compliant display, a full?screen green signal provides immediate visual confirmation that protected content cannot be viewed on that display. The SW HD 4K switchers also provide +5 VDC, 250 mA on the HDMI output for powering peripheral devices such as an Extron UHD4K 101 or HDMI 101 Plus cable equalizer. The SW HD 4K switchers are housed in 1U, half rack width enclosures that are suitable for mounting in a rack or under a table.
