Grounding Cable Melodika MDG30, ground loop hum reducer, Schuko plug, 3 m

Melodika MDG30 is a 3 m grounding cable with a Schuko plug designed to reduce ground-loop hum in audio systems. The cable provides a direct connection to protective earth for audio components, helping to equalize potential differences between devices and reduce mains-related interference that can manifest as hum or noise. Its 3-metre length allows flexible placement of equipment in home and studio environments while maintaining a grounded reference for improved sound clarity.

Advantages

The Melodika MDG30 grounding cable offers a simple, passive method to reduce ground-loop hum without altering signal paths. By providing a stable earth reference via a Schuko plug, the cable helps minimize audible mains hum and related interference in audio chains. Its neutral design works with a wide range of consumer and professional equipment, and the 3 m length accommodates varied rack and room layouts. Installation requires no tools and can be implemented quickly as part of troubleshooting or system setup.

How to use

Connect the Schuko plug of the MDG30 to a properly earthed mains socket, then attach the other end to the device chassis or designated earth point according to the equipment manufacturer’s instructions. Ensure both the grounding cable and the outlet earth are in good condition and that connections are secure. Test the audio system before and after connecting the grounding cable to confirm a reduction in hum. Disconnect power before making chassis connections where required by safety guidelines.

Usage recommendations

Use the Melodika MDG30 only with equipment that provides a dedicated chassis or earth terminal for grounding. If hum persists after grounding, inspect signal cabling, power conditioning, and separate signal and power routing. Do not bypass protective earth requirements of any device; if in doubt, consult a qualified technician.
