KDM401 Quad AV input digital modulator

  

Maximum spectrum efficiency

The KDM401 is a commercial quality quad AV standard definition modulator with integrated multiplexing to combine all four AV inputs in one RF channel, maximising spectrum efficiency. 

Ideal for converting an analogue AV signal either from a satellite decoder, DVD, video surveillance camera or video door phone and modulating it into a digital format (DVB-T) for distribution in a TV cable network. 

With intuitive, simple menus, the KDM401 allows quick and easy programming either by the front panel or a computer using the ethernet port. The housing design allows the unit to be professionally mounted in a 19” rack or on a shelf if required. 

The latest software and hardware advances have been used to provide a product boasting the optimum performance and reliability required for use in a commercial installation.
