Tendak HDMI ARC Audio Extractor User Manual

1. Introduction

The Tendak HDMI ARC Adapter is designed to extract audio from your TV's HDMI Audio Return Channel (ARC) port and convert it into various audio output formats, including optical (TOSLINK SPDIF), coaxial, and analog 3.5mm L/R stereo audio. This allows you to connect your HDTV's internal audio sources (such as built-in streaming apps or TV tuners) to external audio devices like soundbars, speakers, home theater systems, or A/V receivers that may not have HDMI ARC input capabilities.

This device provides a versatile solution for integrating modern TVs with older audio equipment, ensuring high-quality audio transmission. It supports a wide range of sampling rates up to 192KHz and 24-bit S/PDIF incoming bit streams.

2. Connect HDMI Cable: Connect one end of an HDMI cable (HDMI 1.4 or higher recommended) to your TV's HDMI ARC port and the other end to the "ARC IN" port on the Tendak Audio Extractor.
3. Connect Audio Output: Choose your desired audio output method and connect the corresponding cable from the Extractor to your audio device (soundbar, speaker, amplifier, headphones):
   • For digital audio: Use an optical (TOSLINK) cable to the SPDIF output or a coaxial cable to the Coaxial output.
   • For analog stereo audio: Use RCA L/R cables to the L/R output or a 3.5mm audio cable to the 3.5mm stereo output.
4. Power Connection: Connect the provided USB power supply cable to the "DC 5V" input on the Extractor and plug the other end into a USB power source (e.g., a TV's USB port, a USB wall adapter).
5. Power On: Flip the ON/OFF switch on the Extractor to the "ON" position. The power indicator light should illuminate.
6. Configure TV Audio Settings: Access your TV's audio settings menu.
   • Enable the HDMI ARC function on your TV.
   • Set the TV's audio output format to PCM or LPCM. This adapter does not support Dolby AC3/Dolby Digital Plus etc. 5.1 channel audio.

7. Operating Instructions

Once the setup is complete, operating the Tendak HDMI ARC Audio Extractor is straightforward:

• Ensure all cables are securely connected and the Extractor is powered on.
• Select the desired input source on your TV (e.g., a streaming app, a connected device).
• The audio from your TV's ARC channel will now be extracted and outputted simultaneously through the optical, coaxial, L/R, and 3.5mm ports.
• Volume Control: When using the ARC function, the volume needs to be adjusted by your connected audio device (soundbar, amplifier, etc.). The TV remote control can typically control the output volume of the 3.5mm and RCA interfaces, but not the coaxial and optical outputs.
• Important Note: If you experience no sound or static, double-check that your TV's audio output is set to PCM or LPCM, as the adapter does not support Dolby AC3/Dolby Digital Plus.

8. Troubleshooting

If you encounter issues, please refer to the following troubleshooting tips:

• No Sound Output:
  • Ensure your TV's HDMI port is specifically an ARC port and that the ARC function is enabled in your TV settings.
  • Verify that your TV's audio output format is set to PCM or LPCM. This is a common cause for no sound.
  • Check all cable connections (HDMI, audio output, power) to ensure they are secure. Try unplugging and re-plugging them.
  • Ensure the Tendak Extractor is powered on and its power indicator light is illuminated.
  • Try a different HDMI cable, as some cables may not fully support ARC functionality.
  • Power cycle both your TV and the Tendak Extractor (unplug from power for a few minutes, then reconnect).
  • Ensure the volume on your connected audio device is turned up.
• Static or Distorted Sound:
  • Confirm that your TV's audio output is set to PCM/LPCM.
  • Check for loose cable connections.
  • Test with a different audio cable or audio device if possible.
• TV Remote Cannot Control Volume:
  • The TV remote can typically only control the volume for the 3.5mm and RCA (L/R) analog outputs. For optical and coaxial digital outputs, volume must be adjusted on your connected audio device.
• Intermittent Audio:
  • Check power supply stability.
  • Ensure HDMI cable is not too long or damaged.

9. Maintenance

To ensure the longevity and optimal performance of your Tendak HDMI ARC Audio Extractor, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or aerosol sprays, as they may damage the unit.
• Storage: Store the device in a cool, dry place away from direct sunlight, high temperatures, and humidity when not in use for extended periods.
• Handling: Avoid dropping or subjecting the device to strong impacts.
• Ventilation: Ensure the device is placed in an area with adequate ventilation to prevent overheating.
