Employing NVT’s latest generation DigitalEQTMtechnology, the NV-1672 is an 16-channel active
(amplified) hub that allows the transmission of full-motion monochrome or color video for distances up
to 1 mile (1,6km) using Category 2 or better unshielded twisted-pair (UTP) wire. The receiver hub con­tinuously and automatically conditions the video signal, compensating for cable attenuation, wiring
polarity, ground loops, and voltage transients, independent of video signal content.

The unparalleled interference rejection and low emissions allow long run video to co-exist in the
same wire bundle as telephone, datacom, or low-voltage power circuits. this allows the use of shared
or existing cable plant. Ground-lifting ensures no annoying “hum-bars” when ground-potential differ­ences exist. With built-in transient protection, damaging voltage spikes are eliminated.
