The Dual 4K HDMI HDBaseT + USB-C, 3.5mm, and USB-B to A over Cat Extender Wall Plate Transmitter to Audio De-Embedding Box Receiver - 4K 60Hz allows HDMI or USB-C audio/video sources to be extended up to 130ft to a 4K display using a single Cat6a Ethernet cable. This is an ideal solution where USB must be extended alongside HDMI video and audio to interactive whiteboards and displays in conference rooms, classrooms, lecture halls, and many other installation needs that are far beyond the length limitations of standard HDMI cabling. This HDMI HDBaseT receiver is HDCP 2.2 compliant, making sure that the connection between the source and display is secure. Automatic switching is supported, connecting to the last active source. Additional analog audio output pass-through allows for audio distribution. High-speed USB 2.0 pass through is supported over HDBaseT up to 230ft for KVM control of devices such as USB cameras, keyboards, mice, etc. With PoH (Power Over HDBaseT) support, the receiver can send power to the transmitter, so no additional power adapter is required, allowing for greater flexibility in installations. Advanced users can control the transmitter via the RS232 port on the receiver. Note: Ensure a solid reliable connection between the 4K HDMI HDBaseT Extender and critical equipment. We suggest using HDMI Cables with gripping connectors that provide greater port retention than standard HDMI connectors.The Dual 4K HDMI HDBaseT + USB-C, 3.5mm, and USB-B to A over Cat Extender Wall Plate Transmitter to Audio De-Embedding Box Receiver - 4K 60Hz allows HDMI or USB-C audio/video sources to be extended up to 130ft to a 4K display using a single Cat6a Ethernet cable.
