Description
The SK81HU-N is an 8-port HDMI KVM switcher designed to let a single keyboard / video / mouse / USB / audio setup be shared across multiple computers. It supports UHD 4K resolutions up to 3840×2160 and consolidates desktop peripherals to reduce hardware clutter. The unit is engineered to simplify multi-system workflows while maintaining compatibility with common operating systems.
Key features include HDMI 1.4 console connectivity, USB 3.0 console ports and integrated 3.5 mm audio and microphone jacks. The switcher supports cross-computer clipboard and file transfer using standard copy and paste commands, enabling text and file movement without a network connection. It also exposes USB Type B ports for per-computer peripheral connections and provides three USB Type A ports at the console for high-speed device sharing.
From a performance perspective the SK81HU-N supports 3840×2160 video at 30 Hz over HDMI and uses USB 3.0 for fast peripheral throughput. Power is supplied via an external adapter with a maximum consumption of 35W and the product is rated to operate between 0 and 40 degrees C. The unit carries CE, RCM, FCC class B, VCCI and TUV certifications and ships with a two year warranty and a 10 year product life-cycle.
Connectivity is straightforward: a single HDMI console output, HDMI inputs per computer, USB Type A console ports and USB Type B computer ports, plus dedicated 3.5 mm audio and microphone jacks. The switch is compatible with Windows, Linux and Mac hosts and supports standard USB keyboards and mice. The console provides three USB 3.0 Type A ports enabling external storage, input devices or other USB peripherals to be shared among connected systems.
Typical applications include multi-workstation trading desks, broadcast monitoring stations, IT administration benches and control-room operator positions where desk space is limited. Users gain the ability to switch control quickly between hosts while maintaining audio and USB device access. The integrated copy-paste file transfer function reduces friction when moving content between isolated systems without relying on network shares.
Installation is rack or desktop friendly with a compact 440 x 192 x 48 mm footprint and a 2.6 kg chassis weight. Setup requires only HDMI and USB cabling plus the external power adapter, and the front-panel console and simple switching controls make daily operation intuitive. The SK81HU-N is built for continuous use in professional environments and includes compliance and warranty support appropriate for commercial deployments.
