1. Product Introduction
The WUH4ARC-H2 is an ultra-thin auto switcher with four HDMI video inputs and one
HDMI output. This switcher supports HDMI video resolution up to 4Kx2K@60Hz 4:4:4
HDR and multichannel 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 audio return channel (ARC) 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.
