Absolute Acoustics
HDMI/HDBaseT™ Matrix switcher


The Absolute Acoustics® NDS-UHM88 is a HDMI/HDBaseT™ matrix switcher with 8 inputs and 8 outputs capable of transmitting audio and video, control signals and electrical power supply for distances up to 328 ft (100m) over a single twisted-pair cable. Its unique hybrid architecture combines 8 HDMI inputs, 2 HDMI outputs and 6 HDBaseT™ outputs in a compact 2U chassis, and provides advanced features for HDMI signal distribution, such as native support for UHD/4K resolutions, high definition audio formats and compliance with HDCP 2.2 copy protection standard. Each output port features HDMI audio breakout, for direct connection with audio systems, and IR/RS-232 extension ports to remote zone receivers. UHM88 can be controlled manually through buttons on its front panel, 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 a easy way to perform all settings.
