The Absolute Acoustics® NDS-UM44 is a HDMI/HDMI matrix switcher with 4 inputs and 4 outputs capable of transmitting audio, video, and control signals from any source to any display. As an exclusive feature, UM44 extracts digital audio from each HDMI input, for direct connection with audio distribution systems.
With a range of exclusive technologies, UM44 offers advanced features for distributing HDMI signals, such as native support for UHD/4K resolutions, high definition audio formats, and compliance with the new HDCP 2.2 copy protection standard, making it perfect for deployment of multimedia distribution systems in residential or corporate environments. Additionally, all inputs and one output zone of UM44 have HDMI audio breakout, extracting the digital audio contained in the HDMI signal into a pair of RCA connectors.
UM44 can be controlled manually via front panel buttons or remotely, by sending IR or RS232 codes. When connected to an Ethernet network, it can also be controlled over Telnet protocol, or through its web interface - which also works as an easy way to perform all settings. And further expanding the range of features, UM44 can act as an automation hub, forwarding commands received on its control ports via HDMI-CEC to devices connected on each of its outputs.
