The DL-S41-H2 is a slimline HDMI 2.0b auto switcher with four HDMI video inputs and one HDMI output. This switcher supports HDMI video resolutions up to 4Kx2K@60Hz 4:4:4, HDR, and multichannel audio. In addition to 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 and audio output ports from display device. When in auto-switch mode, the switcher will switch to an HDMI input as soon as a new source is connected. When the active source 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.
