Powerful technology, compact dimensions, modular and flexibly expandable the WISI COMPACT HEADEND System OH combines all the advantages of an innovative and affordable headend
WISI Compact Headend OH is easy to configure
With up to 14 module slots it offers channel processing for 14 analogue or 28 digital channels in a 3 HU 19 rack chassis
WISI Compact Headend OH operates on a high efficiency power supply, with low consumption modules in order to make a minimum ecological impact and a low operational cost
The USB connection and the RJ45 interface can be used to execute software updates for the basic unit as well as for the modules
Furthermore, all functions can be furnished from a distance per web browser
