Dual Input Eight Output 8K60Hz Independent Downscaling Audio De-Embedding
The KAMEHA KA280 is a high-performance HDMI 2.1 2×8 splitter, engineered for professional AV environments requiring stable multi-display 8K distribution. It allows switching between 2 HDMI input sources and synchronously distributes the selected signal to 8 HDMI outputs.
With ultra-high 48Gbps bandwidth, the KA280 supports up to 8K@60Hz 4:2:0 12bit, delivering outstanding image clarity, color depth, and smooth motion performance. Each output independently supports 8K → 4K/2K downscalingand HDR to SDR conversion, ensuring full compatibility with both next-generation and legacy displays.
The KA280 integrates advanced switching, signal management, and professional audio extraction into a single powerful device. It supports both auto and manual input switching, giving users flexibility in operation.
Each HDMI output is capable of independent resolution scaling and HDR conversion, making it ideal for mixed display environments. Integrated digital optical (S/PDIF) and balanced/unbalanced analog audio de-embedding with adjustable gain allow seamless integration with professional audio systems.
A built-in HDMI signal generator simplifies installation and troubleshooting by diagnosing HDMI cable and device connection status. Advanced EDID management, equalizer, retiming, and signal driver technologies ensure stable and reliable 24/7 operation in commercial and mission-critical applications.
The KA280 can be controlled via front panel buttons, IR remote, RS-232, or API commands, making it perfect for system integration projects.
