Matrix capability

The ESTONE OZJ4 is a 4x4 HDMI matrix switch that routes any of four source devices to any of four displays simultaneously. It suits installers and enthusiasts who need independent zone control without running multiple dedicated cables.

Build integration

The unit accepts four HDMI inputs and provides four HDMI outputs, each supporting up to 4K at 60 Hz with 18 Gbps bandwidth. HDCP 2.2 compliance keeps protected content flowing, while the EDID extractor lets sources negotiate the correct resolution automatically. IR remote control is included for front-of-room switching.

Bundled control

An IR remote ships in the box for instant input selection from the sofa. The EDID learning function stores display capabilities so sources start at the right mode without manual setup. ARC support passes audio back from compatible displays to an external sound system.

Questions about this item

What is the maximum cable length the ESTONE OZJ4 supports at 4K@60Hz without signal loss?

The matrix works with HDMI 2.0b cables up to 8 metres using AWG26 wire.

Does the ESTONE OZJ4 generate noticeable heat or fan noise during continuous 18.5 Gbps operation?

The unit has no fan and its 230 x 90 x 25 mm metal case dissipates heat passively.

Which audio outputs must my displays or amplifier already provide to use the matrix’s SPDIF and 3.5 mm L/R ports?

You need a display or amplifier with an optical SPDIF input and a 3.5 mm stereo line input.
