  • Converts HDMI to composite AV for legacy displays

Signal conversion for legacy displays

This LUOM adapter converts an HDMI source into composite video and stereo audio through three colour-coded RCA sockets. It accepts standard-definition output at 480i and 576i, making it suitable for older televisions, VHS recorders or DVD recorders that lack digital inputs. The unit supports both PAL and NTSC television standards. No driver installation is required.

Compact enclosure with USB power

The black plastic housing measures 67 mm deep, 55 mm wide and 20 mm high and weighs 37 g. A single HDMI input sits on one side and three RCA outputs on the other, keeping cabling tidy behind a rack or television. A USB power lead is built in and must be connected to a 5 V supply before the converter will operate. The device is incompatible with streaming sticks, phones, tablets and certain game consoles.

USB power cable included

The bundled USB cable draws the 5 V the converter needs from any standard USB port or mains adapter, so no separate power brick is necessary. Plug-and-play operation means the scaler begins downscaling the incoming 1080P signal to composite format as soon as power and both cables are connected. This lets you view modern HDMI sources on legacy composite equipment immediately.

Questions about this item

What video standard does the HDMI-to-CVBS conversion cap the output at?

The converter scales any HDMI input down to standard-definition CVBS at 480i or 576i, so the maximum visible resolution is 480 or 576 interlaced lines regardless of the source.

What are the exact dimensions of the converter box and how much space does it need?

The unit measures 67 mm deep, 55 mm wide and 20 mm high, weighing 37 g, so it fits in a tight AV rack or behind a TV with only a few centimetres of clearance.

Does the adapter need external power and what is the correct way to connect it?

Yes — the included USB power cable must be plugged into a 5 V USB port or charger before the HDMI and RCA cables are attached, otherwise the converter will not function.
