The Crestron® HDMI over shielded twisted pair extender (HD-EXT2-C) delivers professional-grade digital HD AV signal extension for use in a boardroom, classroom, auditorium or residence. Without any special setup or configuration, the HD-EXT2-C enables wire runs up to 100m (330ft) over a single, low-cost shielded twisted-pair (STP) cable. Adding a second STP or UTP cable enables the extension of a stereo analog audio signal alongside the digital signal, perfect for supporting devices that may not include or support a digital audio channel.
