HDMI over HDBaseT™ Extender


The Absolute Acoustics® NDS-970HD is a HDMI over HDBaseT™ extender kit capable of transmitting audio, video, control and Ethernet network signals for distances up to 328ft (100m) over a single twisted-pair cable.

NDS-970HD is capable to extend 1080p video up to 328ft (100m) and 4K/UHD video up to 230ft (70) with embedded multi-channel audio, RS232 and bi-directional IR control signals. Also, a built-in Ethernet extension provides 3 additional ports for connection of streaming and control devices. Both TX and RX units can be remotely powered by PoC technology (a single power supply is required), cleaning up the installation.

And as a singular feature in extensors, the NDS-970 provides a kit of tools for audio signals treatment: via HDMI-ARC and digital optical audio connections, it is possible to send the audio from the display across the system. A pair of RCA connectors at the TX-side make the de-embedding, allowing the connection to multi-room controllers.
