Crackling noise coming from 1 channel - Onkyo Audio Players & Recorders

Sounds like you are picking up some interference first try swapping out the RCA cables you are using to connect that component. also keep your RCA cables away from any 110V AC power lines.

same thing with speaker cables, speaker wire should intersect power lines at 90 degrees and should not run parallel to power lines.

many people use the wires that come with their components. these cables are thin and offer very low performance a thicker higher quality cable with a gold connector will not only better maintain the quality of the signal being transferred between components but will also have better shielding to protect the cable from picking up interference from other electrical components and power lines.


Also should point out that a blown speaker sometimes produces a crackling sound, swap your left / right speakers and see if the crackling sound still comes from that speaker if it does you have a blown / damaged component.
