4K/UHD, 5-Input HDMI Switcher with Mirrored HDMI Outputs

The Atlona AT-UHD-SW-52 is a 5×1 HDMI switcher with dual HDMI outputs, balanced audio outputs, 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 included 19” rack mount brackets. Two units can be mounted side-by-side.
Automatic Display Control
The AT-UHD-SW-52 allows display control using RS-232 signals. When a switcher is integrated with a display, the AT-UHD-SW-52 forces the display to power on automatically when a laptop is connected. At the end of the presentation, when the presenter disconnects the laptop, the AT-UHD-SW-52 forces the display to power off. Ease of presenter interaction with the system and the savings incurred by auto-display shutdown provide a significant return on investment.
- RS-232 – Many displays including projectors, commercial flat panel displays, and some consumer displays can be controlled using the RS-232 signal directly from the switcher. The switcher is able to send commands using RS-232 for automatic display control to compatible displays.
Reliable Auto-Switching
Automatic input selection on the AT-UHD-SW-52 detects an active video signal, rather than looking for the 5-volt, hot plug signal. This means that devices such as DVRs, DisplayPort adaptors and other devices that keep the 5-volt hot, no longer trigger the automatic input selection. This gives far more reliable performance with these products.
4K/UHD 5×1 Switcher with Dual Outputs
The AT-UHD-SW 52 adds 4K/UHD performance and installation flexibility to Atlona’s HDMI small switcher family to meet the needs of professional integration applications. Dual HDMI outputs, balanced audio output, EQ, and volume control add to the AT-UHD-SW-52’s long list of features. Incorporating internal video distribution eliminates the need for an external DA to reduce system complexity to save integrators time and money.
The AT-UHD-SW-52 is ideal for use in applications where:
- Two displays are needed to cover presentations in large rooms or where a confidence monitor is needed at the presenter’s podium along with the primary room display.
- Installers need an easy-to-integrate, five-input HDMI switcher with 4K/UHD capability to support multiple sources and mirrored displays to work with any control system.
