Viablue ferrite reducers eliminate high-frequency electromagnetic interference (EMI) and the noise it induces within your audio cables. This is essential for designing high quality Hi-Fi cables, providing a clean signal for optimal sound reproduction.

These ferrites are very easy to install, by sliding over the cable and fixing with two M4 1.5mm hexagon socket screws.

Ferrite is a ceramic material composed of iron oxide and other metallic elements. All of them are electrically non-conductive, making it a very good insulator.
