Signal conversion

The LUOM HDMI2SDI micro converter takes a single HDMI source and produces two simultaneous SDI outputs for broadcast monitors or long cable runs. It accepts HDMI 1.3 with HDCP 1.3 and handles embedded audio without separate wiring. The unit draws power over USB so no external adapter is required. Plug-and-play operation works across Windows, macOS, Linux and Android without driver installation.

Sustained operation

A metal enclosure provides passive cooling that keeps the converter stable during continuous streaming or recording sessions. Built-in ESD protection guards the circuitry against static discharge in studio environments. The dual SDI outputs maintain locked 4:2:2 and 4:4:4 sampling at 2.97 Gbit/s for 3G-SDI and 1.485 Gbit/s for HD-SDI without frame drops over extended periods. LED status indication confirms active links at a glance.

Distance limits

SDI cable reach is rated at 100 metres for 3G-SDI, 200 metres for HD-SDI and 300 metres for SD-SDI, so the installation topology decides whether this converter fits the run. It only converts HDMI to SDI; reverse conversion or daisy-chaining multiple units of the same type is not supported. Buyers needing SDI-to-HDMI translation or longer single-cable runs must choose a different device.

Questions about this item

Does the LUOM HDMI2SDI run hot or draw much power when left on continuously?

The metal enclosure provides passive heat dissipation and the spec sheet states no external power supply is needed, so typical draw is low enough for USB power.

What cables or sources must I already have to use the converter?

You need an HDMI Type A source such as a camera or PC and up to two SDI cables to reach your monitors or switcher.

Will the LUOM HDMI2SDI work with my older 720p or 1080i SDI monitors?

Yes, it auto-detects 3G-SDI, HD-SDI and SD-SDI and outputs 720p@60Hz, 1080i@50/60Hz or 1080p@24/25/30/50/60Hz to match legacy displays.
