The small fan or buzz noise you are hearing from your Fender 150 bass unit is likely due to normal wear and tear. Over time, components inside electronic devices can begin to wear down or become loose, which can cause the unit to generate noise. However, it's possible that the noise is being amplified through the speakers due to a grounding issue or other electrical interference.
Before attempting to open up the unit and clean it, try some basic troubleshooting steps to isolate the issue:
- Try using a different cable to connect your PC or iPad to the Fender 150 bass unit. Sometimes cables can become damaged or worn, which can cause noise or interference.
- Move the Fender 150 bass unit to a different location in the room to see if the noise changes or disappears. Sometimes nearby electrical devices or lighting can cause interference with audio equipment.
- Try using different speakers to see if the noise is still present. If the noise disappears, it's possible that the speakers are causing the issue rather than the Fender 150 bass unit itself.
If none of these steps resolve the issue, it may be necessary to open up the Fender 150 bass unit to inspect and clean the components inside. However, if you're not familiar with electronics and don't feel comfortable working on the unit yourself, it's best to take it to a professional technician for servicing.
It's important to note that while the noise may be annoying, it's not necessarily an indication of a major problem with the unit. If the Fender 150 bass unit is still functioning properly and producing the sound you love, it may be best to simply live with the noise rather than risking damage to the unit by attempting to fix it yourself.
