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.
