• Limited lifetime warranty

Employing NVT’s latest generation DigitalEQTMtechnology, the NV-3272 is an 32-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.
