Question about ION Audio Vinyl Recording Turntable
Posted by Anonymous on
I am going to hazard a guess, I have lots of experience with traditional turntables, but not with USB turntables. Here is some theory that may also apply to the USB turnbable. Turntables of old and new that are not USB have a GROUND wire (a single flexible conductor not connected to the plug). The ground wire is supposed to go to the chassis of the amplifier or receiver. If it is not used. There will be a 60Hz hum added to the turntable's signal. It makes the sound garbled and unpleasant. Your turntable may have such a wire. If so, ground the wire to the chassis of the computer. If it doesn't have the wire. check to see if you have all three prongs on your terminal strip(the rounded large prong is the ground). If you don't the chassis of the computer will not be grounded so you may get the hum from that source as well. If the outlet that your outlet strip is plugged into does not have a proper ground, then that could be the source.
Check to make sure that there are no breaks of your ground between the turntable and the wall outlet.
Replace the offending cables or parts until you are sure.
If there is a grounding wire coming out of the turntable, connect it to the chassis of the computer.
Here are some other points that are important
Important: All of the power in your computer and sound system should be connected to the same phase of the breaker panel in your house If it goes into the same wall outlet. that is best.
This ground issue is important in turntables.
This may not be the problem, but it certainly is very possible.
I worked in professional sound system design for recording studios and large venue (concert) sound systems.
Whenever possible, these folks require the power to be from a unified phase and source point. on Otherwise they have serious hum issues.
Have a Happy New Year,
