Extron Quantum Ultra Connect 128 (part number 60-1898-12) — a rack-mount videowall processing engine built to drive large-format multi-display walls from a single 3U chassis.

The Connect 128 accepts twelve independent HDMI/DVI sources and routes them across eight scaled HDMI outputs, giving integrators a self-contained way to build, resize, and reposition windows across a videowall without relying on an external PC-based controller. Onboard 4K processing tops out at 4096x2160, with parallel HDMI connections available when a layout needs 50 or 60 Hz refresh at full 4K. Dual gigabit Ethernet ports, an RS-232 port, and USB control give system integrators several paths into Extron's Videowall Configuration Software (VCS), SIS commands, or Telnet, so the processor drops into existing AV-over-IP or serial control schemes with minimal extra hardware.

Key Capabilities

• 12 HDMI/DVI inputs, 8 scaled HDMI/DVI outputs in one 3U rack-mount chassis
• Native 4K processing up to 4096x2160 for crisp large-format videowalls
• Dual gigabit Ethernet plus RS-232 and USB for flexible control paths
• Runs Extron VCS software, SIS commands, and Telnet for system integration
• 182W full-load draw, drops to 38W in power-save mode

Where It Is Used

The Connect 128 fits large operations centers, broadcast and network operations rooms, trading floors, and higher-education command centers where a single processor needs to feed many scaled windows to a wide videowall array from a compact rack footprint.
