Ikusi MHD-201 Class A High Definition Digital Modulator



Ikusi MHD-201 Class A High Definition Digital Modulator

The MHD-201 is a module designed and manufactured completely with in-house technology, that is able to treat different video and audio formats,to create a high-definition output channel in COFDM or in IP.

The unit has various types of inputs:
• Two analogue audio and video channels, through RCA connectors.
• One digital audio and video channel in HDMI, through an HDMI connection.
• One digital audio and video channel in HD-SDI, through a BNC connector.

This product solution fulfils the needs of video signal distribution in residential facilities, hospitals, hotels and unique buildings and also CCTV integration in existing installations. The MHD-201 has also an USB interface for HD video contents playback from a USB memory automatically. This functionality allows different applications such as digital signage, creating an information channel or the integration of any source of existing video into the TV network, allowing simultaneously obtaining the video signal plus a modulated channel.

Programming the modulator by the end user can be done in two different ways:
• Through the IKUSI SPI-300 programming unit.
• Connecting a local or remote web interface
