HD4420K


4K 60Hz 4-in 8-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. 4x4 matrix switching functionality enables simultaneous 4-channel local and 4-channel remote video playback with synchronized output.

Long-Distance Transmission Performance

Supports 150m transmission at 1080P @60Hz and 120m transmission at 4K @60Hz via Cat6 cable, with lossless uncompressed signal transmission.

HDBaseT Technology Transmission

Transmits uncompressed audio and video signals over standard Cat6 network cables via HDBaseT technology, ensuring ultra-long distance transmission 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.
