Signal Conversion
The ATEN VC840 is an HDMI to 3G-SDI audio video converter designed for professional broadcast and AV installations. It accepts a single HDMI Type A input and provides dual BNC outputs alongside analog stereo and coaxial digital audio connections. The unit converts signals in real time while preserving quality through reclocking technology.
Installation Suitability
This converter suits engineers integrating HDMI sources into SDI infrastructure for live production, post-production or signal distribution over long cable runs. It supports automatic format detection across SD-SDI, HD-SDI and 3G-SDI standards. Buyers who need HDMI output, multi-input switching or embedded audio extraction from SDI should consider alternative devices.
Output Reach
The single specification that determines suitability is the maximum transmission distance over RG6 cable: up to 300 metres for SD-SDI, 150 metres for HD-SDI and 90 metres for 3G-SDI. These distances define whether the converter can bridge the required link between source and destination without additional repeaters or fibre extenders.

Questions about this item
How much power does the VC840 draw and does it run hot when converting HDMI to 3G-SDI all day?
The VC840 is a compact passive converter measuring 1.20" x 4.21" x 4.80" and weighing 0.64 lbs with no fan, so it generates minimal heat and draws very little power during continuous operation.
What cables or sources must I already have to connect the HDMI input and the two BNC outputs on this converter?
You need an HDMI Type A source cable for the input and two BNC cables for the dual SDI outputs; analog stereo uses red and white RCA cables while coaxial digital audio uses a yellow RCA cable.
Will the VC840 work with my older SD-SDI monitor that only accepts 270 Mbps signals?
Yes, the VC840 automatically detects and supports SD-SDI at 270 Mbps (SMPTE 259M) up to 300 m over RG6, as well as HD-SDI at 1.485 Gbps and 3G-SDI at 2.97 Gbps.
