Bi-directional HDMI Switch and Splitter

The ROFAVEZCO unit operates as a bi-directional HDMI switch and splitter, handling one input to two outputs or two inputs to two outputs. It supports Ultra HD 4K resolution and is designed for users who need to route signals between sources and displays, including setups where a television lacks an eARC connection for a soundbar.

Passive Operation with SPDIF Audio Extraction

The device draws power from an external supply and adds no active cooling, so it runs silently. Video bandwidth reaches 18 Gbps for 4K at 60 Hz and 1080p at 120 Hz with HDR and Dolby Vision pass-through. HDMI outputs carry Dolby Digital 7.1-channel audio while the SPDIF port delivers 5.1-channel audio only.

4K to 1080p Down-scaling via EDID Control

A front-panel scaler toggle lets you down-scale a 4K signal to 1080p on one output while the other passes the native resolution. EDID selection is managed by a button on the chassis, allowing manual choice of audio and video formats. CEC control is available on HDMI output one only.

Questions about this item

How do I set the EDID mode on the ROFAVEZCO splitter so the soundbar receives eARC audio?

Connect sources to the inputs and displays to the outputs, then use the panel button to select the EDID setting that matches your soundbar; set Output 2 to soundbar mode for ARC/eARC operation.

What cable length limit applies to keep 4K 60 Hz signals stable on this unit?

Use HDMI 2.0 cables shorter than 3 metres; longer or non-compliant cables can cause loss of picture or sound.

Which audio format drops out first when I push both HDMI and SPDIF outputs at high bandwidth?

SPDIF is limited to 5.1-channel audio, while HDMI OUT can pass 7.1-channel; the SPDIF path reaches its ceiling before the HDMI path.
