Black Box Video Extender Kit

Emerald 4K - Powering the World's Most Demanding Environments

Emerald 4K transmitters and receivers deliver pixel-perfect HD and 4K/60 video over standard IP networks. Operators get instant, seamless access to both physical and virtual systems with sub-second switching, flawless video, stereo audio, and transparent USB 2.0 support for mission-critical peripherals - including Wacom® tablets.

For administrators, Emerald provides centralized, secure management with flexible configuration and always-on reliability. Add the Boxilla Central Manager for enterprise-wide control, and you can scale from a single extender to hundreds or thousands of endpoints across buildings, campuses, or global networks - without forklift upgrades or costly new hardware.

Key Capabilities:

Scalable by Design

Start small - as extenders or a local switchable matrix - and expand into a fully managed enterprise control (KVM) system with Boxilla. Emerald grows with your control room.

Enterprise Access, instantly

Switch between sources in under half a second across your entire enterprise - buildings, campuses, or WAN - using existing IP infrastructure. Connection folders simplify management across the ecosystem.

4K Digital Video, Lossless Quality

Emerald is the first KVM platform to deliver pixel-perfect 4K DisplayPort video at 60 Hz over copper or fiber IP networks. With mathematically lossless compression, every pixel is delivered at 60 fps, 8-bit color depth. Start with HD today (Interchangeable with Emerald SE/PE) and migrate to 4K at your own pace.

Virtualization Made Simple

Seamlessly access VMware, Microsoft, and Citrix environments using RDP, RemoteFX, and PCoIP. No extra hardware. No training curve. Just full control.

Fail-Safe Operation

Dual network ports and flexible copper/fiber SFP+ connectivity deliver always-on resilience. Even if one link fails, operations stay uninterrupted.

Standards-Based Networking

Emerald runs on standard IEEE 802.3 Ethernet switches - Gigabit for HD, 10G for 4K, with 100G uplinks for large deployments. Built with proven, standards-based hardware from Black Box or your existing infrastructure.

Emerald Works with Your Entire Black Box Ecosystem

Seamlessly integrate with DKM matrix switching, Freedom II KM switches, ControlBridge room control, and Boxilla centralized management - giving you one unified platform for KVM, AV, and room automation.
