Product Information
The Leviton HDMI 4 x 1 Switcher is an ultra thin automatic switcher with four HDMI
video inputs and one HDMI output. This switcher supports HDMI video resolution up
to 4K x 2K@60Hz 4.4.4 HDR and multichannel audio. EDID information (describing
signal formats your display supports) can be passed through from the display, or
there are multiple built-in settings and user defined settings to simplify installation.
The switcher will extract digital stereo audio to provide an analog source for an audio
system. The switcher also supports audio return channel (ARC) for transmitting
audio back to the HDMI input port from the connected display.

User Defined EDID Settings
Up to five EDID settings can be customized for specific applications using the
steps below.
1. Rename the user defined EDID using the following format:
EC_xx_xxxx_xxx.bin
• EC represents EDID
• xx represents EDID ID. It can be 11-15.
• xxxx represents the video parameter
• xxx represents the audio format
Example: EC_11_720P_LPCM.bin
2. Power the switcher on and connect a PC with the USB cable to the FW port.
The PC will automatically detect a U-disk named BOOTDISK.
3. Double click the U-disk. A file named READY.TXT will be displayed.
4. Copy the user defined EDID (see example above) to the BOOTDISK U-disk.
5. Reopen the U-disk to verify the file name was automatically changed from
READY.TXT to SUCCESS.TXT. If it successfully changed, the user defined
EDID has been imported into the switcher and saved as its corresponding
EDID ID.
6. Repeat steps 3 through 5 to copy other user defined EDIDs to the BOOT-
DISK U-disk.
7. Remove the USB cable and connect the adapter to power the switcher on.
8. The new EDID is invoked via the 4 position DIP switch. The EDID ID and its
corresponding switch status are shown in the list below.

ARC Mode
Audio Return Channel (ARC) allows audio from a display to pass through an HDMI
cable to an audio processing device such as an AV amplifier. When the switcher is
in ARC mode the ARC stream will pass to the active HDMI source device on port 4 if
the device can process the signal. NOTE: ARC is available only through the HDMI
input port 4. Both the display and the amplifier need to be designed to support ARC.
