You use a digital coaxial audio cable to transmit digital audio signals between devices, typically from a source (like a TV, Blu-ray player, or game console) to a receiver (like a soundbar, AV receiver, or speaker system).
Here's a step-by-step guide:
Connecting the Coaxial Cable
- Identify the Ports: Locate the "DIGITAL AUDIO OUT (COAXIAL)" port on your source device (e.g., TV). Also, identify the "DIGITAL AUDIO IN (COAXIAL)" or simply "COAXIAL" port on your receiving device (e.g., soundbar). These ports are usually orange or black and labeled accordingly.
- Connect the Cable: Firmly insert one end of the digital coaxial audio cable into the "DIGITAL AUDIO OUT (COAXIAL)" port on your source device. Then, connect the other end of the cable into the "DIGITAL AUDIO IN (COAXIAL)" port on your receiving device. Ensure a secure connection.
- Power On and Select Input: Turn on both your source device (TV, Blu-ray player, etc.) and your audio receiving device (soundbar, AV receiver, etc.). On the audio receiving device, select the appropriate input source. This is usually labeled "Coaxial," "Digital In," or something similar in the device's menu or input selection options.
- Adjust Audio Settings (If Necessary): On your source device, you may need to adjust the audio output settings to ensure the audio is being sent through the coaxial output. Look for options related to digital audio output or audio encoding. Common settings include PCM, Dolby Digital, or DTS. The compatible options will depend on your receiving device's capabilities. Ensure the setting is compatible with the audio formats your source is outputting.
- Test the Audio: Play audio from your source device. You should now hear the sound through your receiving device (soundbar, speakers, etc.). If you don't hear any sound, double-check your connections, input selections, and audio output settings on both devices.
Troubleshooting Tips
- Secure Connections: Make sure the coaxial cable is securely connected to both the source and receiving devices.
- Input Selection: Verify that you have selected the correct input on your receiving device.
- Audio Output Settings: Ensure your source device is configured to output audio through the coaxial connection and is set to a compatible format.
- Cable Integrity: If you still have no sound, try using a different coaxial cable to rule out a faulty cable.
Coaxial vs. Optical (TOSLINK)
While both digital coaxial and optical (TOSLINK) cables transmit digital audio, they use different methods. Coaxial cables use an electrical signal, while optical cables use light. Both are capable of transmitting high-quality audio, but some argue that coaxial cables are less susceptible to interference. Ultimately, the best choice depends on the available ports on your devices.
