1 Introduction
1.1 Product Introduction
The UH-4U-8K is an auto switcher with four HDMI video inputs and one HDMI output.
This switcher supports HDMI video resolution up to 8K@60Hz 4:2:0 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.
