The HMS-30 is a device that converts HDMI signal of 1080i and 525i into HD-SDI or SD-SDI signal. It is compact and easy to carry. It allows embedding eight channels audios of HDMI signals or two analog audios into the output SDI signal.

Input signal supports 1080i/59.94 and 525i/59.94 of HDMI v1.1, and automatically switches them.
Built-in cable equalizer at the input section compensates maximum 30m of cable length.
