Precautions for use:

1. Please use the standard HDMI cable that meets the requirements, connect the device and then power on.
2. The OUTA interface can only output audio. Please connect it to the HDMI input of audio devices such as power amplifier or echo wall.
3. The audio output of the optical fiber and RCA interface can be turned on/off using the SPDIF key on the remote control.
4. Analog audio can only be output when the audio format is LPCM, so when using analog audio output, it is recommended to select the EDID mode in 2CH mode.
5. If you want to use ARC or CEC functions, you must connect the TV to the OUTB port. When using ARC, the HDMI input of the TV must support and have ARC enabled.
6. The product has the power off memory function, the setting state of the selected channel and function will be saved, and the saved data will be automatically retrieved for configuration after the power off.

Connections:

1. Use an HDMI cable to connect the HDMI output end of the DVD/ set-top box/Blu-ray device to the HDMI IN port of the separator. Please make standard HDMI2.1 cable.

2. Connect the HDMI OUT port of the separator to the HDMI input terminal of the TV monitor using an HDMI cable. Please make standard HDMI2.1 cable.

Connect the OUT(ARC) interface of the HD378X1 to the HDMIARC interface of the audio source device such as the TV through the HDMI cable (standard HDMI2.1 cable) (Note: please connect the HDMI port marked with “ARC”!) , set the audio output mode of the TV and other devices to ARC output. Please make standard HDMI2.1 cable.

3. When digital audio is used, connect the SPDIF OUT port of the separator to the optical fiber input end of the power amplifier through an optical fiber cable.

4. When using analog audio, connect the R/L OUT port to the power amplifier analog audio input through the Lotus audio cable.

5. When using HDMI Audio Only audio, connect the audio cable to the power amplifier through HDMI (the interface is forcibly fixed to V1.3 output to solve the compatibility problem).

6. Connect the DC head of the power adapter to the DC5V port of the separator, and then plug the adapter into the power socket. (Select a 5V 1A charger with output voltage (be sure not to use a variable voltage fast charge)).

Flexible switching output:

2.0CH: In this mode, priority output stereo audio output (audio source needs to be switched to PCM) supports decoding up to 24bit/192Khz audio sampling rate.

5.1CH: Support fiber 5.1 digital surround audio (DTS, Dolby, AC3) source code output; Analog output interface] No output is available.

7.1CH: The audio format is LPCM, and the audio extracted by HDMI separation will be output in the HDMI interface.

(Note: If the TV or monitor does not support channel 7.1, there is no audio signal.)

PASS: indicates the audio EDID passthrough mode. The audio output format in this mode depends on the audio processing capability of the connected device at the output end.

Common fault diagnosis and handling methods:

Before powering on, you should carefully check whether the connection line is normal, and you must ensure that all interfaces are correctly connected.

Common troubleshooting methods are as follows:

No.	Fault phenomenon	Reasons and solutions
1	No electricity	1. Check whether the power plug is securely inserted 2. Check whether the standby state of the power supply is entered
2	No sound, abnormal sound	1. Check whether the sound channels and interfaces are correctly and reliably connected 2. Check whether the format of the input audio signal is supported by the product 3. Check whether the EDID mode is properly set 4. Check whether the power amplifier/TV volume is set to silent
3	No image, the picture is abnormal	1. Check whether the input signal source is correctly connected to the display device and is powered on 2. Check whether the output resolution of the signal source is greater than the resolution supported by the display device 3. The EDID information of the device is incorrectly obtained. You are advised to power off and restart the device 4. Check the specifications and quality of the cable (HDMI cable requirements meet the HDMI2.1 standard)
