Troubleshooting Guide
This applies to the following Rumblewood Subwoofers…
Facing challenges with your subwoofer? Let’s navigate through some common issues and their potential fixes.
No Sound or Low Volume
- Power: Is the subwoofer turned on? Ensure the power cord is securely plugged in.
- Volume: Adjust the subwoofer’s volume or gain control.
- Receiver/Amplifier: Check its settings – the subwoofer might be muted or set to a low volume.
- Cables: Securely connect the RCA cables. For LFE input, use just one cable.
Distorted or Muddled Sound
- Crossover: Fine-tune the low-frequency cutoff to prevent sound overlap and distortion.
- Cable Quality: Consider replacing a damaged or substandard RCA cable.
Intermittent Sound or Dropouts
- Cables: Check for loose or worn-out connections.
- Interference: Keep the subwoofer away from other electronic devices or potential sources of wireless interference.
Subwoofer is Too Boomy
- Positioning: Relocate the subwoofer, especially if it’s close to a corner.
- Tuning: Reassess the low-frequency cutoff or use an auto-calibration if available.
Subwoofer Humming
- Power Source: Plug the subwoofer into a different electrical outlet to rule out grounding issues.
- Cable Disconnect: Disconnect the RCA cable from the subwoofer. If the hum stops, the issue might be upstream of the subwoofer.
- Interference: Electronic devices or dimmer switches can cause a hum. Relocate the subwoofer or the potential interference source.
