Kramer VS-88UT 8x8 Matrix Switcher wHDMI/HDBaseT 2.0
The Kramer VS-88UT is an all-in-one 8×8 presentation system that combines a 4K60 (4:2:0) HDMI/HDBaseT 2.0 matrix switcher, long-reach HDBaseT extension, a fully programmable master room controller, USB extension, PoE on HDBaseT outputs, and a built-in power amplifier. It switches video, embeds/de-embeds audio, and drives both HDMI and HDBaseT outputs—making it a compact hub for modern, mixed-signal classrooms, conference rooms, and training spaces.
Key Features
- 8×8 4K Matrix: Route six HDMI and two HDBaseT inputs to two HDMI and two HDBaseT outputs at up to 4K60 (4:2:0), 10.2 Gbps; HDCP/DVI compliant with Deep Color and 7.1 PCM. Includes active source/acceptor detection and auto-switching.
- HDBaseT Extension: Extend up to 100 m at 4K60 (4:2:0), 130 m at 1080p/36bpp, or 180 m in Ultra Mode at 1080p; PoE provided on HDBaseT outputs.
- Integrated Control System: Onboard master controller with RS-232/RS-485, IR, GPI/O, relays, K-NET™, and Ethernet—plus multi-client IP control (up to 15 clients).
- Audio DSP & Amplification: 4 balanced (or 8 mic) + 4 unbalanced stereo inputs, 2 balanced line outs, audio-follow-video, breakaway, global mute, and a 2×50 W @ 4 Ω power-amplified speaker output.
- USB & LAN Extension: USB 1.1/2.0 link extension (Type-A/B ports) and Ethernet tunneling over HDBaseT for peripheral connectivity and control.
- EDID & Management: Advanced per-input EDID tools, embedded web pages, Protocol 3000 API, and Kramer Network / K-Config compatibility.
- Installer-Friendly: 19″, 2U rackmount chassis with universal AC power; non-volatile memory retains last configuration after power cycles.
