LUOM 4K 60Hz HDMI Matrix 4x2 18.5 Gbps Switch Splitter with SPDIF 3.5mm Audio (OZJ2-1)

4x2 HDMI matrix with audio extraction

This LUOM matrix switch routes four HDMI sources to two independent displays while extracting audio through optical SPDIF and 3.5 mm stereo outputs. It suits home-theatre owners, installers and small commercial venues that need simultaneous routing to a projector and a TV or to a display and an audio system. The unit handles 4K 60 Hz signals with HDCP 2.2 compliance.

Passive cooling with no fan noise

The aluminium enclosure dissipates heat without active cooling, so the switch runs silently in living rooms, meeting rooms or hotel lobbies. Power draw stays low because the device only processes and redistributes the incoming TMDS stream; no upscaling or frame-rate conversion is performed. Typical operation remains well within the 18.5 Gbps bandwidth budget.

Replaces basic 4-to-1 switchers

A single box now covers source selection, dual-zone distribution and audio breakout that previously required two or three devices. The jump is worth it when you need independent output routing — for example sending a console to the living-room TV while the same or another source feeds a bedroom display — and want integrated 3.5 mm or optical audio for a soundbar or amplifier. Buyers who need more than two simultaneous outputs or automatic downscaling beyond 4K to 1080P should look at larger matrix models.
