Turntables are susceptible to hum, which is a low-frequency noise that can be caused by a variety of factors. One common cause of turntable hum is the RCA cables that connect the turntable to the amplifier or receiver.
RCA cables are made of copper and are susceptible to picking up electrical noise from their surroundings. This noise can be caused by power lines, other electronic devices, and even the turntable itself.
If you are experiencing hum from your turntable’s RCA cables, there are a few things you can do to try to fix the problem:
- Check the RCA cables: Make sure that the RCA cables are properly shielded. If they are not, the shielding may be damaged or not connected properly.
- Change the RCA cables: If you have tried checking the RCA cables and they are still causing hum, you can try replacing them with a new set of cables.
- Move the turntable away from other electronic devices: If the turntable is close to other electronic devices, such as computers or televisions, the hum may be coming from those devices. Try moving the turntable away from these devices to see if the hum goes away.
- Use a ground loop isolator: A ground loop isolator is a device that can help to reduce or eliminate hum by breaking the loop of electricity that is causing the hum.
- Have the turntable serviced: If you have tried all of the above and the hum is still there, it may be necessary to have the turntable serviced by a qualified technician.
By following these tips, you can help to reduce or eliminate the hum from your turntable’s RCA cables.
Here are some additional things to keep in mind about turntable hum and RCA cables:
- Cables made of higher quality materials, such as oxygen-free copper, are less likely to pick up noise.
- Cables with thicker insulation are also less likely to pick up noise.
- Cables with a ground wire can help to reduce or eliminate hum.
- It is important to make sure that the RCA cables are properly connected to the turntable and the amplifier or receiver.
If you are experiencing hum from your turntable’s RCA cables, it is important to try to identify the source of the noise. Once you have identified the source, you can take steps to reduce or eliminate the hum.
