Audio Format Setting

Audio Setting DIP switch is located on front panel of the device. It is used to set output audio formats. The function of each setting is shown in the following table.

embedding, digital audio de-embedding and ARC audio can work properly.
Note: The audio information of EDID will be limited in this mode.
2 (Right)| Full copy EDID of the connected display, and no limitation of audio formats.
Note: In this mode, the audio de-embedding may have no sound, users may need to set audio format of input source manually.

The supported audio formats in different settings are as follows:

Audio Mode| Output 1| | Output 2|
---|---|---|---|---
HDMI Audio| Analog
Audio| HDMI Audio| SPDIF Audio
1| PCM 2.0 only| PCM 2.0 only| Up to 5.1ch| Up to 5.1ch
2| All HDMI 2.0 audio formats1| PCM 2.0 or no audio output2| All HDMI 2.0 audio format| Up to 5.1ch or no audio output3

Note:

• all HDMI 2.0 audio formats: means fully supports audio formats in HDMI 2.0 specification. E.g., PCM 2.0, LPCM 5.1/7.1, Dolby TrueHD, DTS‐HD Master Audio, Dolby Atmos and DTS:X.
• PCM 2.0 or no audio output: audio de‐embedding will have sound only when the audio of the source is set to PCM2.0 format.
• Up to 5.1ch or no audio output: audio de‐embedding will have sound only when the audio of the source is set to 5.1 channels and below.

IR Remote Control
The included remote-control handset can be used to turn on and off a CEC- enabled display device and to switch the HDMI source for each display device. Note:

• As the internal battery inside the remote control of our device is packaged by insulation slice, please remove the insulation slice before use.
• Please make sure that the remote is pointed directly at the IR receiver window.

System Code Switch
The IR Remote provided with the Matrix is shipped in “00” IR system code. In the event that Remote’s IR signal interferes with IR devices, e.g., TV, DVD player, the Remote can be switched to “4E” code by short pressing the System Code Switch on the Remote panel. At the same time, you must redefine the IR system code of the Matrix using the API command.

RS232 Control

• Advanced users may need to control the matrix through RS232 serial communication. Connect a control PC or control system to the RS232 port of the switcher. Detail API Commands, please refer to a separate document “API Command Set_4KMX42-H2A”. A professional RS232 serial interface software (e.g., Serial Assist) may be needed as well.
• Before executing the API command through RS232 serial connection, please ensure RS232 interface of the device and the control PC are configured correctly.
