Turntable Connection To Usb Port Causes Buzzing

Recommended Posts

There must be a simple solution somewhere. So here's my dilemma: I have a 25-year old turntable (with direct drive), and have connected via the Roxio cables and mixer box to my Win 7 OS USB port. The WAV file is transferred to my computer and replays beautifully. But, if I try to monitor the sound while the transfer is taking place, the turntable connection produces bad buzzing and popping feedback over the computer's sound system--very disturbing. This buzzing and popping does not transfer into the Wav file, and it immediately goes away when I disconnect the turntable from the USB port. Is there a grounding method that will alleviate this noise interference and still allow me to listen to the actual recording? Thank you for any suggestions. Sandgrass

Are you using the turntable by itself, or you using it with a receiver/amplifier? If you are using it with the receiver/amplifier, ground it to the back of the amp?

Hi Grandpabruce--No amplifer. I purchased hp 5.1 surround sound speakers(self-powered ? ?) that connect through the speaker ports. Can I attach a ground wire somewhere in the chain from the turntable to the USB port? The computer is brand new--hp 580t desktop with tons of power, speed and memory. Thank you so much for the reply.

It has a phono plug?
