5.2.2. eARC Splitter Mode (1-in-2-out)

In this mode, the device extracts audio from your TV's eARC/ARC port and sends it simultaneously to two separate eARC/ARC compatible audio devices.

• Connect your TV's HDMI (eARC/ARC) port to the HDMI OUT / eARC IN porta sullo splitter.
• Connect your first eARC/ARC audio device (e.g., soundbar) to the HDMI IN1 / eARC OUT1 porta.
• Connect your second eARC/ARC audio device (e.g., amplifier) ​​al HDMI IN2 / eARC OUT2 porta.
• Ensure the 4th DIP switch is in the "Down" (0) position for eARC Splitter mode.
• Connect the USB power cable to the CC/5V port and then to a 5V USB power adapter (not included).

6. Istruzioni per l'uso

6.1. Switching HDMI Inputs (2x1 Switch Mode)

When operating in 2x1 HDMI Switch mode:

• Pulsante del pannello frontale: Press the "Select" button on the front panel to cycle between HDMI IN1 and HDMI IN2.
• Telecomando: Use the corresponding input selection buttons on the IR remote control to switch between HDMI IN1 and HDMI IN2.

Figure 6.1: Two Ways to Switch Inputs: Remote and Button.

6.2. EDID Settings and Mode Selection

The EDID DIP switch allows you to configure the device's behavior, particularly for eARC audio and overall operation mode. The DIP switches are labeled 1, 2, 3, and 4. "Up" typically means '1' or 'ON', and "Down" means '0' or 'OFF'.

Figure 6.2: EDID DIP Switch Configuration for eARC Modes.

• 4th DIP Switch "Up" (1): eARC Switch Mode (1-in-1-out)
  • When the 4th dial is up, it functions as an eARC switcher, allowing only one of the two eARC output ports (eARC OUT1 or eARC OUT2) to output sound. You can switch between them freely.
• 4th DIP Switch "Down" (0): eARC Splitter Mode (1-in-2-out)
  • When the 4th dial is down, it works as an eARC splitter, transmitting TV sound to both eARC OUT1 and eARC OUT2 simultaneously for synchronized high-quality audio.

The first three DIP switches (1, 2, 3) are used to set specific audio EDID modes. Here are common configurations:

Table 6.1: EDID Settings for Audio Modes. ("0" = switch down, "1" = switch up)

Important Note for ARC/eARC:

• When using the ARC feature, both the TV and audio device need to support ARC.
• When using the eARC function, the soundbar should be connected to either the eARC Out1 or eARC Out2 port.
• If the audio format is 7.1CH, the coaxial and optical ports may not output sound.

7. Specifiche

8. Risoluzione Dei Problemi

In caso di problemi, fare riferimento ai seguenti problemi comuni e alle relative soluzioni:

• Nessuna uscita video:
  • Ensure all HDMI cables are securely connected and are high-quality, certified 4K@60Hz cables.
  • Verify the power adapter is connected and providing sufficient power (5V).
  • Check if the correct input is selected on the switch (using the "Select" button or remote).
  • Try connecting the source directly to the display to rule out cable or source issues.
  • Adjust the EDID settings using the DIP switches. Sometimes, forcing a specific resolution or audio format can resolve compatibility issues.
• Nessuna uscita audio:
  • Ensure your audio device (soundbar, amplifier) is correctly connected to the appropriate output port (eARC OUT1/OUT2, Optical, Coaxial, 3.5mm).
  • Verify the audio input on your audio device is correctly selected.
  • For ARC/eARC, ensure both your TV and audio device support ARC/eARC and that the feature is enabled in your TV's settings.
  • Check the EDID DIP switch settings. If 7.1CH audio is selected, optical and coaxial outputs may not function. Try a 5.1CH or 2.0CH setting.
  • Ensure the "eARC Audio" button on the unit is enabled.
  • If using eARC Splitter mode, ensure the 4th DIP switch is "Down" (0). If using eARC Switch mode, ensure it's "Up" (1) and you've selected the correct eARC output.
• Intermittent Signal / Flickering:
  • Use shorter, high-quality HDMI cables, especially for 4K@60Hz signals.
  • Assicurarsi che l'alimentazione sia stabile e sufficiente.
  • Verificare la presenza di interferenze da altri dispositivi elettronici.
• Il telecomando non funziona:
  • Ensure there are no obstructions between the remote and the IR receiver on the unit.
  • Check and replace the battery in the remote control if necessary.
  • Point the remote directly at the IR receiver.
