Grounding Cable Melodika MDG20, Schuko to Ground, 2 m, Hum Reduction

Melodika MDG20 is a 2 m grounding cable with a Schuko plug designed to provide a dedicated earth connection for audio equipment and other devices. The cable helps reduce mains hum and ground loop noise by linking chassis or signal gear to protective earth, improving signal clarity and lowering audible interference in sound systems. The design is intended for straightforward use with Schuko-compatible outlets and grounded devices.

Advantages

The Melodika MDG20 offers a simple passive solution to reduce hum without altering signal chains or requiring additional electronics. Its 2 m length allows flexible placement of equipment while maintaining a reliable earth connection. By providing a stable protective earth path, the cable helps minimise low-frequency hum and unwanted noise caused by ground loops, contributing to clearer audio reproduction and more consistent performance across different setups.

Suitable for

• Home audio systems and powered speakers
• Studio equipment including mixers and amplifiers
• Turntables and phono preamps prone to hum
• AV installations where chassis grounding is required
• Any Schuko-compatible device needing a dedicated earth connection

Key specifications

• Connector type: Schuko plug to grounding lead
• Cable length: 2 metres
• Primary function: Protective earth/ground connection to reduce mains hum
• Application area: Audio equipment, chassis grounding, AV setups
• Cable construction: flexible insulated conductor suitable for indoor use

How to use

Connect the Schuko plug of the MDG20 to a properly grounded mains outlet and attach the other end to the device chassis or the designated earth terminal on your audio equipment. Ensure the outlet provides a confirmed protective earth and that connections are made with the system powered off. After connecting, power up the equipment and verify that hum or ground loop noise is reduced. If necessary, try alternative grounding points on the chassis to find the most effective connection for noise mitigation.

Usage recommendations

Use the grounding cable only with grounded Schuko outlets and compatible equipment. Avoid using the cable in wet or hazardous environments. If hum persists after correct grounding, inspect other signal cables, isolation transformers, or consult an audio technician for further diagnosis. For best results, combine proper cable routing, balanced connections where available, and secure chassis grounding.
