3. Ensure the LED indicator on the converter illuminates, indicating it is powered on.

2. Audio Input Connection

Choose one of the following input methods based on your audio source:

ARC Input Mode:

1. Connect an HDMI cable from your ARC-compatible television's HDMI ARC output port to the ARC input port on the converter.
2. Ensure your television's HDMI port supports ARC functionality.

TOSLink Input Mode:

1. Connect an optical fiber cable from your audio source (e.g., game console, Blu-ray player) to the Toslink input port on the converter.

Coaxial Input Mode:

1. Connect a coaxial cable from your audio source to the Coaxial input port on the converter.

3. Audio Output Connection

Connect the converter's output ports to your desired audio receiving devices:

• For Digital Audio: Connect an optical fiber cable to the Toslink Output or a coaxial cable to the Coaxial Output, then connect to your amplifier, soundbar, or home cinema system.
• For Analog Audio: Connect RCA L/R cables to the Stereo R/L Audio Output, or a 3.5mm audio cable to the 3.5mm Jack Output. Connect these to your amplifier, speakers, or headphones.

Operating Instructions

1. Input Mode Selection

Use the A-T-C switch on the input panel to select the active audio input:

• Set the switch to 'A' for HDMI ARC input.
• Set the switch to 'T' for TOSLink optical input.
• Set the switch to 'C' for Coaxial input.

2. Audio Format Configuration

For optimal performance and to ensure audio output, especially when using the R/L or 3.5mm jack outputs, it is crucial to configure the audio format on your source device (e.g., TV, game console).

• Important: If you experience no sound output, set the audio format of your signal source (e.g., TV audio settings) to PCM or LPCM.
• The converter supports DTS / DSD / LPCM formats for Toslink/Coaxial output. However, for R/L or 3.5mm jack outputs, only LPCM/PCM audio format input is supported.

Troubleshooting

If you encounter issues while using the VEDINDUST HDMI ARC Digital to Analog Audio Converter, please refer to the following common problems and solutions:

• No Sound Output:
  • Ensure the converter is properly powered via the DC5V input and the LED indicator is on.
  • Verify that the A-T-C input selection switch is set to the correct input mode (A for ARC, T for Toslink, C for Coaxial).
  • Check the audio settings on your source device (TV, game console, etc.). The audio output format must be set to PCM or LPCM, especially for analog (RCA L/R or 3.5mm) outputs.
  • Confirm that all audio cables (HDMI, optical, coaxial, RCA, 3.5mm) are securely connected to both the converter and your audio devices.
  • Test with different audio cables if possible, to rule out faulty cables.
• ARC Function Not Working:
  • Ensure your television's HDMI port specifically supports Audio Return Channel (ARC). Not all HDMI ports are ARC-enabled.
  • Check your TV's audio settings to ensure ARC is enabled and configured correctly.
  • Try restarting both your TV and the converter.
• Poor Audio Quality:
  • Ensure all connections are tight and free from interference.
  • Verify that the audio format from your source is compatible with the converter's outputs (LPCM/PCM for analog outputs).
  • Avoid using excessively long or low-quality cables, which can degrade signal integrity.
