Atlona AT-UHD-SW-51 Description

The Atlona AT-UHD-SW-51 is a 5x1 HDMI switcher with auto-switching and advanced control capability. The switcher supports 4K/UHD @ 60 Hz with 4:2:0 color, offers 3D pass-through, and 10.2 Gbps bandwidth. With front panel buttons and IR control, it can be a standalone switcher. Designed as a cost-effective, easy to install solution, the switcher offers a web-based GUI for easy set-up and management of EDID and HDCP. Additional control options include auto-switching, front panel selector, and compatibility with RS-232 or TCP/IP-based control systems. Audio features include de-embedding of PCM audio over HDMI to either S/PDIF or two-channel analog audio outputs; pass-through of Dolby TrueHD® and DTS-HD Master Audio; plus an Audio Return Channel feed to the S/PDIF output from the HDMI display. The compact, 1U, half-rack width enclosure is easily installed in rack mounted systems with the 19” rack mount brackets. Two units can be mounted side-by-side.

The AT-UHD-SW-51 automatically selects an input source based on detection of the 5 volt hot plug detect (HPD) signal, as well as active video. This ensures reliable auto-switching operation for all video sources, including DVRs, DisplayPort / Mini DisplayPort adapters, and other devices that always maintain the HPD line at the 5 volt “high” state but may not be delivering active video.
4K/UHD 5x1 Switcher

The AT-UHD-SW 51 adds 4K/UHD performance to Atlona’s HDMI small switcher family to meet the needs of displays and sources with resolutions beyond 1080p. In addition, the switcher offers advanced audio features. Auto-switch, the additional TCP/IP control flexibility, and overall control system neutrality give integrators a significant time savings during installation.

The AT-UHD-SW-51 is ideal for use in applications where:

4K video switching must be added to AV systems with upgraded 4K displays and sources that were designed around a high end audio processor/switcher limited to 1080p.
Installers need a no-nonsense, cost-effective 5x1 HDMI switcher with 4K/UHD support for easily-managed applications with multiple sources and one display for corporate and residential applications that will work with any control system.
