How to Connect Optical Audio Cable to Aux: A Simple Guide to Seamlessly Transfer Audio Signals

To connect an optical audio cable to an aux input, you’ll need a digital-to-analogue converter (DAC) that can convert the optical signal to analogue and is compatible with the aux input. Simply plug one end of the optical cable into the optical audio output on your device and the other end into the optical input of the DAC. Then, use a standard RCA or 3.5mm audio cable to connect the DAC’s analogue output to the aux input on your device. This setup allows you to transmit audio from devices with optical outputs to devices with only aux inputs.

  1. Identify the connections: First, determine the type of connections your devices have. If your audio source has an optical audio output and your receiving device (such as a speaker or amplifier) has only an aux input, you’ll need to convert the optical signal to analog.
  2. Obtain a DAC: Purchase a digital-to-analog converter (DAC) that supports optical input and analog output. This device will convert the digital optical signal to analog, compatible with your aux input device.
  3. Connect the optical cable: Plug one end of the optical audio cable into the optical output of your audio source and the other end into the optical input of the DAC.
  4. Connect the DAC to the aux input: Use a standard RCA or 3.5mm audio cable to connect the analog output of the DAC to the aux input of your receiving device.
  5. Test the connection: Once everything is connected, test the audio transmission to ensure it’s working properly.

directly connecting an optical audio cable to aux isn't possible due to the different signal types they carry. But fret not, there's a simple workaround using a Digital-to-Analog Converter (DAC). Here's how to achieve this connection:

What you'll need:

Digital-to-Analog Converter (DAC)
Optical cable (already have)
Aux cable (might be needed depending on your DAC)
RCA to aux cable (might be needed depending on your DAC)
Connection Steps:

Optical Cable: Plug one end of the optical cable into the optical output (Toslink) port on your device (TV, game console, etc.).
DAC Connection: Plug the other end of the optical cable into the DAC's digital input, typically labeled Toslink or Optical.
Aux Cable (Optional): If your DAC has RCA output ports, you'll need an RCA to aux cable to connect it to your speaker system's aux input.
Power Up the DAC: Some DACs require a separate power source, while others draw power from the optical connection. Refer to your DAC's manual for specific instructions.
Audio Output Selection: On your device with the optical output, you might need to navigate the settings menu and choose the optical output as the active audio source.
Additional Tips:

DACs come in various models. Ensure the one you choose has compatible input and output ports for your setup.
Double-check the connection points to ensure everything is securely plugged in.
If you encounter any audio issues after connecting, consult your device and DAC manuals for troubleshooting steps.

Step 1: Gather the necessary equipment

Before starting the connection process, make sure you have all the required equipment:

  • Optical audio cable
  • Aux cable
  • Optical to analog converter (if necessary)
  • Audio devices (TV, soundbar, speakers, etc.)

Step 2: Determine the compatibility

Check if your audio devices have both optical and aux ports. Most modern TVs and soundbars are equipped with an optical port, while the auxiliary input can be found on speakers, stereos, or older audio devices. The optical port is a square-shaped port with a small flap, usually labeled as “Toslink” or “Optical.”

Step 3: Connect the optical audio cable

  1. Locate the optical audio output port on your audio device. It is usually labeled as “Optical Out.”
  2. Insert one end of the optical audio cable into the optical output port. Ensure that it is inserted securely.
  3. Locate the optical input port on the other device you want to connect to, such as a soundbar or speakers. It is typically labeled as “Optical In.”
  4. Insert the other end of the optical audio cable into the optical input port of the second device.

Make sure the cable is firmly connected to both devices to ensure a proper audio signal transfer.

Step 4: Check and set the audio settings

Once the optical audio cable is connected, you need to check the audio settings on your devices:

  1. On your TV or audio source device, go to the audio settings menu.
  2. Select the audio output option and choose the optical audio output as the preferred option.

If you encounter any issues with the audio output, refer to the device’s manual or troubleshoot the settings accordingly.

Step 5: Using an optical to analog converter (if necessary)

If the device you want to connect your optical audio cable to only has an aux input instead of an optical input, you will need an optical to analog converter:

  1. Connect the optical audio cable from the audio device to the input port of the optical to analog converter.
  2. Take the aux cable and connect one end to the output port of the converter.
  3. Connect the other end of the aux cable to the aux input of the device.
  4. Ensure all connections are secure and tight.

This converter allows you to convert the optical audio signal into an analog format that can be understood by devices with only an aux input.

Step 6: Enjoy your audio

After completing all the necessary connections, you are ready to enjoy high-quality audio from your devices. Make sure to test the audio output by playing some music or a movie soundtrack.

Remember to adjust the volume levels on both your audio source device and the connected audio device to ensure a balanced and pleasant sound experience.
