Questions & Answers▲
What does the AVMatrix Mini SC1221 do and what is it used for?
The AVMatrix Mini SC1221 is a compact signal converter that converts HDMI signals into 3G-SDI signals. It is suitable for professional broadcast and production environments where HDMI sources need to be fed into SDI-based infrastructures.
How many SDI outputs does the converter have?
The converter has two SDI outputs, so that the converted signal can be passed on to two SDI devices simultaneously without the need for an additional splitter.
Which SDI standards are supported at the output?
At the output, SD-SDI, HD-SDI and 3G-SDI are supported according to the SMPTE standards supported. The device detects the incoming HDMI signal and automatically selects the appropriate SDI standard for the output.
Which video resolutions and frame rates are supported?
SD formats such as 525i 59.94 and are supported 625i 50 and HD formats from 720p with frame rates of 24, 25, 30, 50, 59.94 and 60 frames per second to 1080i 50/59.94/60 and 1080p with frame rates of 23.98, 24, 25, 29.97, 30, 50, 59.94 and 60.
How is the converter powered?
