4x2 HDMI Matrix for Multi-Source Setups

The LUOM OZJ2 routes four HDMI sources to two independent displays at up to 4K@60Hz with 18.5Gbps bandwidth. It supports HDMI 2.0b, HDCP 2.2, deep color up to 48-bit and 3D formats. Built-in audio extraction provides optical, coaxial and 3.5mm outputs for external sound systems. Control is via front-panel buttons or the included IR remote.

Sustained Signal Integrity Over Extended Runs

The matrix maintains 18.5Gbps throughput and TMDS clock rates up to 600MHz continuously, preserving 4K@60Hz RGB 4:4:4 without dropouts during long sessions. HDCP 2.2 handshake remains stable across both outputs simultaneously. Smart EDID management ensures consistent source recognition when switching inputs repeatedly. The DC 5V 600mA supply delivers steady power for uninterrupted operation.

Thermal and Acoustic Profile in Daily Use

Passive cooling keeps the unit silent with zero fan noise in typical indoor environments. Operating temperature range spans -15°C to +45°C, so normal room conditions stay well within limits. The compact 170x56x24mm metal enclosure dissipates heat effectively during continuous 4K switching. Power draw stays at the rated 600mA maximum, adding negligible load to the circuit.

Questions about this item

How much power does the LUOM OZJ2 draw when running all day?

The unit is rated for a maximum working current of 600mA from the included 5V DC adapter, so continuous operation stays within that limit.

What cables and sources must I already have to use the 4x2 matrix?

You need up to four HDMI source devices and two HDMI displays, plus HDMI cables for each connection; the box includes the 5V power supply and IR remote.

Will the matrix pass 4K@60Hz from my older 1080p Blu-ray player and 4K streaming box to both outputs?

Yes, it supports HDMI 2.0b and HDCP 2.2/1.4 with EDID management, so mixed-resolution sources up to 3840x2160@60Hz are handled on both HDMI outputs.
