|This issue is usually caused by a tracking issue on the turntable. To test if it is the turntable at fault or the speakers, reverse the RCA jacks on the control speaker, red to white and white to red. If the issue now occurs on the other speaker, it is the turntable at fault. Please contact your turntable manufacturer for instructions on how to properly set the tracking. If the issue remains on the same channel it is a problem. Please contact our customer service team for troubleshooting and assistance.
