Setup
Follow these steps to correctly set up your KabelDirekt TOSLINK Optical Audio Cable:
- Identify Ports: Locate the "Optical Out" or "S/PDIF Out" port on your source device (e.g., TV, game console) and the "Optical In" or "S/PDIF In" port on your receiving device (e.g., soundbar, amplifier).
- Remove Protective Caps: Carefully remove the small red or clear protective caps from both ends of the TOSLINK cable. These caps protect the delicate optical fiber tips.
- Connect Cable: Insert one end of the TOSLINK cable into the optical output port of your source device. Ensure the connector is aligned correctly (the flat side of the connector should match the flat side of the port) and push firmly until it clicks into place.
- Connect to Receiver: Insert the other end of the TOSLINK cable into the optical input port of your receiving device, ensuring proper alignment and a secure connection.
- Select Input: On your receiving device (soundbar, amplifier), select the corresponding optical input source. Refer to your device's manual for specific instructions on input selection.

Operating Instructions
Once the KabelDirekt TOSLINK Optical Audio Cable is securely connected between your source and receiving devices, it operates automatically. Digital audio signals are transmitted as light pulses through the fiber optic core, providing clear and precise sound without electromagnetic interference.
- Ensure both connected devices are powered on.
- Verify that the correct audio output setting is selected on your source device (e.g., TV audio output set to "Optical" or "Digital Out").
- Confirm the correct input source is selected on your receiving audio device (e.g., soundbar input set to "Optical").
Maintenance
To ensure the longevity and optimal performance of your optical audio cable, follow these maintenance guidelines:
- Handle with Care: Avoid bending the cable sharply, as this can damage the internal optical fibers and impair signal transmission.
- Keep Connectors Clean: Dust and debris can interfere with the optical signal. If the connectors become dirty, gently clean them with a lint-free cloth or a specialized optical cleaning tool. Avoid touching the optical tips directly.
- Store Properly: When not in use, store the cable in a clean, dry environment. If disconnecting for an extended period, reattach the protective caps to prevent dust accumulation on the optical tips.
- Avoid Pulling on Cable: Always grasp the connector housing when plugging or unplugging the cable, rather than pulling on the cable itself.
Troubleshooting
If you experience issues with your KabelDirekt TOSLINK Optical Audio Cable, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Cable not securely connected; incorrect input selected on audio device; protective caps not removed. | Ensure both ends of the cable are fully inserted and clicked into place. Verify the flat side of the connector aligns with the port. Select the correct optical input on your soundbar/amplifier. Confirm protective caps are removed. |
| Intermittent Sound or Static | Damaged cable; dirty optical tips; loose connection. | Inspect the cable for visible damage or sharp bends. Gently clean the optical tips if necessary. Re-seat the cable firmly into both ports. |
| Audio Sync Issues | Device processing delay; incorrect audio settings on source device. | Check audio delay settings on your TV or audio receiver. Ensure your source device is outputting a compatible audio format (e.g., PCM stereo if your receiver doesn't support Dolby Digital/DTS). |
