Matrix 4×2 HDMI Switch

The ESTONE OZJ2 is a 4×2 HDMI matrix that routes four sources to two displays independently. It supports 4K at 60 Hz with 18.5 Gbps bandwidth and HDCP 2.2 compliance. Audio extraction is available via optical, coaxial and 3.5 mm ports on output A. ARC return audio works only through output A when the connected TV supports ARC.

Installers needing independent dual-display routing

This unit suits installers who need to send different 4K sources to two screens simultaneously. It is not for buyers who require more than two output zones or who need ARC on both outputs. Users wanting audio extraction on output B should look elsewhere, as extraction and ARC are limited to output A only.

Simple IR or button switching with external power

The matrix ships with a 5 V power adapter, an IR remote and a front-panel button for input selection. Installation is straightforward: connect sources, displays and power, then switch via remote or button. The most common issue is forgetting that ARC and audio extraction function solely on output A, leading to silent output B when those features are expected.

Questions about this item

Do I need a separate power supply for the 4×2 matrix?

The unit ships with a 5 V DC adapter rated at 600 mA; plug that in before connecting any sources.

Will my 1080p projector work on Output B while a 4K@60 Hz TV uses Output A?

Yes — each output negotiates its own EDID, so the projector can stay at 1080p while the TV receives 3840×2160 at 60 Hz.

How can I confirm ARC audio is actually returning through Output A?

Connect the TV’s ARC-enabled HDMI port to Output A, then check the optical or coaxial port for a live Dolby or DTS 5.1 signal while TV audio plays.
