7. Troubleshooting
If you encounter issues with your J-Tech Digital Optical Audio Matrix, refer to the following common problems and solutions:
- No Audio Output:
- Ensure the matrix is powered on and the Power LED is lit.
- Verify that all optical cables are securely connected to both the source devices and the matrix, and from the matrix to the output devices.
- Check that the correct input source is selected for the active output channel (A or B).
- Confirm that your source device is outputting digital optical audio and that your receiving device is set to the correct optical input.
- Ensure the audio format (PCM, DTS, Dolby Digital 5.1) is supported by both the source and receiving devices.
- Remote Control Not Working:
- Check the battery in the remote control and replace if necessary.
- Ensure there are no obstructions between the remote control and the IR Remote Sensor on the matrix.
- Confirm you are within the effective range and angle of the remote control.
- Intermittent Audio:
