Noise filters - Hum and EMI

Ground Loop Isolators and Noise Filters:
Ever wondered why sometimes your stereo speakers start to hum when you plug certain components in?
The most likely cause of humming in audio equipment is due to a ground loop in your home or apartment mains power wiring. A ground loop occurs through differences in resistance in the electrical system. When you connect your computer to your stereo, a path is provided for electricity to flow from one wall socket to another as the electrical system tries to balance itself. This causes your speakers to hum.
Ground-loop Isolators decouple ground connections between equipment sources or speakers eliminating hum and noise. Available in single line configurations with mono mini 3.5 male to female, RCA male to female or dual RCA for left/right stereo applications.
