1. Product Introduction
The WUH4ARC-8K is an auto switcher with four HDMI video inputs and one HDMI
output. This switcher supports HDMI video resolution up to 8K@60Hz 4:2:4 HDR+ and
High Definition audio. Except passing EDID information from the display, there are
multiple built-in EDID settings to simplify an installation. The switcher will de-embed
digital stereo audio to provide an analog audio source for an existing audio system.
The switcher also supports enhanced audio return channel (eARC) for transmitting
audio back to HDMI input port from the connected display.
In auto-switch mode, it switches to an HDMI input as soon as a new source is
connected. When the active input is removed, the switcher will select the first source
on the lowest numbered input. The switcher may also be controlled via RS232, IR with
the included remote, or from the source button on the front of the switcher.
