Description

The Gefen 8×8 4K Ultra HD HDMI Matrix Switcher is a compact matrix designed to route up to eight HDMI sources to eight HDMI displays. It supports 4K DCI and 4K Ultra HD signals and preserves advanced audio formats and HDCP compliance. This unit provides a rack-friendly footprint with surface-mountable options and a clear front-panel display.

Key capabilities include independent routing of eight sources to eight outputs, support for resolutions up to 4096 x 2160 at 24 Hz and 3860 x 2160 at 60 Hz in 4:2:0, and pass-through of 3D and Deep Color. The matrix supports LPCM 7.1 and HBR audio formats such as Dolby TrueHD and DTS-HD Master Audio. Advanced EDID management and Lip Sync pass-through simplify integration with a variety of source devices and displays.

Performance specifications include a maximum pixel clock of 300 MHz and 12-bit Deep Color support up to 1080p. The matrix is HDCP 1.4 compliant and supports DVI sources or displays via HDMI-to-DVI adapters. The front-panel display and status LEDs provide clear routing and lock indicators for system monitoring.

Connectivity options include eight locking HDMI inputs, eight locking HDMI outputs, a mini-B USB port, DB-9 RS-232, and an RJ-45 Ethernet port for IP control. The unit can be controlled via front-panel buttons, the included IR handheld remote, RS-232, Telnet, UDP, or the built-in web server interface. Gefen Syner-G software assists with initial IP discovery and Show-Me configuration tasks.

Typical applications include digital signage installations, control-room switching, corporate AV distribution, and educational AV systems where multiple 4K sources must be delivered to multiple displays. The matrix is suited to environments that require audio format fidelity and straightforward EDID handling. Its compact size makes it suitable for under-table or shallow-rack installations where space is limited.

Installation and operation are designed to be straightforward – connect HDMI sources and displays, attach power and network cables, and configure routing via the front panel or network interface. Firmware updates are field-upgradeable through the web server to maintain compatibility and add features over time. The robust design and industrial operating range support long-term, reliable AV distribution.
