The Zeevee HDb2380 is an 8 channel dual QAM modulator that features a 480i digital video encoder, the best feature is that normally this would take 8 rack spaces but this unit fits in a 1RU spot. Convert every one of your sources into a digital cable channel by connecting to the 8 composite video sources, then on the same coax network you can combine them with hundreds of other cable channels. You can then view your channels but must use the tuner built into your HD display.
Installation and configuration is easy only taking about 10 minutes, your can even add or upgrade your channels very quickly with the color LCD front panel and ethernet port.
