The Marshall VAC-12SH connects an SDI source to an HDMI display while retaining an SDI loop output. It supports common SD, HD and 3G-SDI formats with automatic detection. This makes it useful for adding an HDMI monitoring position to an existing SDI video path.
Marshall VAC-12SH Features
- SDI-to-HDMI viewing connection. The converter takes an SDI input and provides HDMI output for a compatible display. It allows an HDMI monitor to be used at a point in an SDI production system.
- Supported SD through 3G formats. SD-SDI, HD-SDI and 3G-SDI are supported, including specified 1080p modes up to 60 fps. This accommodates a range of established video formats without implying UHD conversion.
- SDI feed remains available. The loop output retains an SDI connection for onward equipment. A monitoring display can therefore be added without making HDMI the only available output at that location.
- Automatic input recognition. Automatic SDI format detection reduces the input-selection work needed when supported sources change. The receiving HDMI display must still accept the resulting video format.
- Embedded audio with the picture. 48 kHz SDI audio is supported alongside video conversion. This allows compatible embedded program sound to accompany the HDMI monitoring feed rather than requiring a separate audio connection.
- Reclocked signal connections. Reclocking supports signal transport through the conversion point. Dolby TrueHD and DTS-HD are not supported over the SDI interface, so those consumer audio formats are outside this converter's stated SDI workflow.
