Troubleshooting
If you encounter issues with your Bobtot B89 system, refer to the following troubleshooting tips.
No Sound Output
- Check Power: Ensure the subwoofer is powered on and not in standby mode.
- Verify Connections: Double-check all speaker cables and audio input cables are securely connected to the correct ports.
- Select Correct Input: Ensure the system's input mode matches the audio source you are using (e.g., if using HDMI ARC, select ARC input).
- Adjust Volume: Increase the master volume and individual speaker volumes.
- TV Audio Settings (for ARC/Optical/Coaxial inputs): If connecting to a TV via HDMI ARC, Optical, or Coaxial, you may need to adjust your TV's audio output settings. Set the Digital Output Audio Format to PCM. Some TVs may not pass through digital audio correctly without this setting.
