AV extender transmitter & receiver TECHLY IDATA EX-HL81TYP — up to 3840×2160, Cat6/Cat6a/Cat7, DC 12V, transmitter 272×96.5×23mm, receiver 75×80×18mm
Techly IDATA EX-HL81TYP is a wired AV extender set that includes a transmitter and a receiver designed to extend HDMI audio and video signals over structured Ethernet cabling. The system supports video resolutions up to 3840×2160 (4K) and uses Cat6, Cat6a or Cat7 cable for transmission. Both units are powered from a 12 V DC source and the compact receiver and larger transmitter dimensions allow flexible mounting in meeting rooms, digital signage installations, training facilities or home AV setups.
The extender replaces long or multiple HDMI cables with a single, cost-effective copper network cable while preserving video clarity and PCM audio transmission. It supports HDCP and provides protection against electrostatic discharge, lightning and overvoltage, helping to improve reliability in commercial and institutional environments. The design provides a local transmitter unit and remote receiver unit that together enable distances suitable for common AV deployments, with practical dimensions for installation behind displays or on racks.
Connect an HDMI source (PC, Blu‑ray player, DVR or other HDMI output) to the transmitter HDMI input, connect the transmitter and receiver using a Cat6/6a/7 cable, then connect the receiver HDMI output to the display. Provide 12 V DC power to both units via their DC-in jacks. Ensure cable terminations and routing avoid sources of strong electromagnetic interference and use appropriate cable lengths within the specified distance guidelines to maintain signal integrity.
For best results, use high-quality Cat6a or Cat7 cable for 4K signals and keep cable runs within the recommended distances. Verify display and source settings match supported resolutions and enable HDCP-compatible modes when required. When installing in commercial environments, secure the units on racks or behind displays and plan power access for both transmitter and receiver.
