Sometimes, after setting up your brand new, expensive, home stereo or home theater system, you turn it on expecting pristine sound and instead get a low frequency hum coming from your speakers, ruining your "perfect sound." Low frequency hum can be caused by several things; in most cases, fixing it is not too complicated.
Instructions
1. Check the connections between components and make sure they are secure before proceeding to the next Step. Sometimes, loose connections can cause a hum.
2. Separate the audio cables from the power cables; electromagnetic interference from the power cables can cause stereo hum. Use cable ties to secure the audio cables away from the power cables.
3. Plug in a surge protector to the outlet, and then plug all the components into that surge protector.
4. Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
5. Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, connect the ground wire to a screw on the electrical outlet.
