1. Product Introduction
The DV-HSW4K-41AUD is an ultrathin auto switcher with four HDMI video inputs and
one HDMI output. This switcher supports HDMI video resolution up to 4K@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 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.
1.1 Features

8.2 User Defined EDID Setting
There are five EDID settings that can be customized following the below operations.
1) Rename the user defined EDID according to the following format.
EC_xx_xxxx_xxx.bin
EC: Represents EDID.
xx: Represents EDID ID. It is 11~15.
xxxx: Represents the video parameter.
xxx: Represents the audio format.
Example: EC_11_720P_LPCM.bin
2) Power on the switcher, and then connect the switcher to the PC with USB cable.
The PC will automatically detect a U-disk named of “BOOTDISK”.
3) Double-click the U-disk, a file named of “READY.TXT” to view.
4) Copy the user defined EDID (such as EC_11_720P_LPCM.bin) to the
“BOOTDISK” U-disk.
5) Reopen the U-disk to check the filename “READY.TXT” this should automatically
become “SUCCESS.TXT”, if yes, the user defined EDID was imported into the
switcher and saved as its corresponding EDID ID successfully.
6) Repeat the above third to fifth step to copy another user defined EDID to the
“BOOTDISK” U-disk.
7) Remove the USB cable, connect the adaptor to power on the switcher.
8) The new EDID also can be invoked via the 4-pin DIP switch directly. The EDID ID
and its corresponding switch status are shown in the below list.

9. ARC Mode
Audio Return Channel (ARC) allows audio from a display to pass “upstream” through
an HDMI cable to an audio processing device, such as an AV amplifier. When ARC
mode is active on the switcher, the ARC stream will pass to the active HDMI source
device if it can process the signal.
Only the fourth HDMI input port features ARC, when the display and AV amplifier
support ARC, the audio connection diagram is shown below:
