Signal conversion and connectivity

The LUOM HDMI to 3 RCA Converter transforms an HDMI input into composite CVBS video at 480i or 576i plus stereo audio through both 3 RCA jacks and a 3.5 mm jack. It accepts sources up to 1920 x 1080 at 60 Hz and includes a USB power cable for operation. The aluminium alloy housing weighs 150 g.

Sustained operation and heat management

The metal enclosure acts as a passive heatsink, allowing the converter to run continuously without active cooling or driver installation. A PAL/NTSC selector switch sets the output standard for the target region. Power is drawn from the supplied USB adapter, so the source device must remain powered during use.

Interface limits and one-way design

The HDMI input supports resolutions up to 1920 x 1080 at 60 Hz, but the composite output is fixed at standard-definition 480i or 576i, so high-definition detail is lost. The device only converts from HDMI to RCA; it cannot pass signals in the reverse direction. Buyers needing upscaling or HDMI capture should consider a different class of converter.

Questions about this item

Does the aluminium casing keep the converter cool when it runs all day?

The aluminium alloy shell provides good heat dissipation so the unit stays cool during continuous use.

What must I already own to power the converter?

You need a USB power source such as a wall adapter or powered hub to supply the 5 V USB port on the converter.

Will my older composite TV accept the 480i or 576i CVBS signal from this converter?

Yes, the converter outputs standard-definition 480i and 576i CVBS with a PAL/NTSC switch for compatibility with legacy composite displays.
