HD8820K


4K 60Hz 8-in 16-out HDMI Matrix Switch + HDBaseT Extender All-in-One

Supports RS232, IR & TCP/IP Control


Products / 4K 60Hz Extenders

2-in-1 Integrated Design

Combines HDMI matrix switching and long-distance HDBaseT signal transmission in one unit. 8x8 matrix switching functionality enables simultaneous 8-channel local and 8-channel remote video playback with synchronized output.

Long-Distance Transmission Performance

Supports lossless 150m transmission at 1080P @60Hz and 120m transmission at 4K @60Hz via standard Cat6 network cable.

HDBaseT Technology Transmission

Transmits uncompressed ultra-high definition audio and video signals over Cat6 network cables via HDBaseT technology, ensuring long-distance playback without signal degradation.

Independent Audio Output

Equipped with built-in COAX coaxial and L/R analog audio independent output ports for flexible audio separation and external audio system connection.

4K 60Hz Ultra-HD Resolution

Supports ultra-high resolution up to 3840 × 2160 @60Hz with YUV4:4:4 chroma subsampling, 18Gbps bandwidth, and HDR10+, HLG, Dolby Vision high dynamic range formats.

POC Single-Side Power Supply

Power over Cable (POC) technology enables single-side power supply; the remote receiver requires no additional power source, ideal for complex installation environments with limited power access.

HDMI CEC Functionality

Integrated HDMI Consumer Electronics Control (CEC) allows seamless one-touch control of all connected HDMI devices for simplified operation.

Minimized Signal Attenuation

All-in-one matrix switch and extender design eliminates the need for additional transmission adapters or cables, avoiding signal attenuation and compatibility issues caused by multiple device connections.
