The Ion USB turntable is designed to transfer the audio signal from a vinyl record to a computer. This audio signal can then be converted into a digital audio file that is compatible, unlike the vinyl record, with being played on a computer or a MP3 player or a cell phone. Getting rid of the hum from an audio signal being transferred by the Ion USB turntable to the computer requires following a few steps in precise order. The procedure will ensure that the digital file made from the vinyl record is free of any hum and sounds as clear as possible.
Place the Ion USB turntable next to the computer on a table. Loosen the grounding screw on the back of the Ion USB turntable with your fingers. Wind one end of the grounding wire around the grounding screw on the back of the Ion USB turntable. Loosely screw the grounding screw back into the Ion USB turntable. Unscrew the grounding screw on your amplifier with your fingers and wind the other end of the grounding wire around the screw. Loosely screw the grounding wire back into the amplifier.
Hold the vinyl record in one hand and swipe the anti-static brush against side one. Reverse hands and swipe the anti-static brush against side two. Put the vinyl record down on the Ion USB turntable with side one facing up. Turn the speed selection knob to "33."
Clean the USB output on the back of the Ion USB turntable with the compressed air. Clean a USB input of the computer with the compressed air. Insert one end of the audiophile-grade USB cable into the USB output of the Ion USB turntable. Insert the other end of the audiophile-grade USB cable into the USB port of the computer that just had the compressed air blown against it.
Eject the computer's DVD disc tray. Place the audio recording disc that comes with the Ion USB turntable on the disc tray. Close the disc tray. Double-click on the icon of the disc when it appears on the desktop. Click on the installation program inside of the window that appears. Follow the menu directions to install the audio recording program to the computer's hard drive. Eject the disc when the installation is complete.
Run the audio recording program. Select "USB" from the "Sources" menu. Select an audio format, such as "USB" or "WAV" from the "Audio format" menu. Click on the "Advanced" button. Select the "Noise reduction" check box in the window that appears. Click on "OK" to close the window. The digital audio file that will now be recorded from the vinyl record will be free of any hum from the Ion USB turntable.
Static electricity, which can contribute to hum, can be eliminated from the Ion USB turntable by placing an anti-static mat beneath it.
Seriously scratched vinyl records will cause audio noise and pops that can be only lessened, not removed, from the digital audio file.
