The Supra LoRad MD06DC-EU/SP mains block provides premium shielding, noise filtering, and protection from surges and harmful DC currents. Its advanced NIF (Non-Intrusive Filtering) and DC-blocker technology, developed in partnership with Ben Duncan Research (UK), reduce high-frequency interference from household devices, suppressing up to 40 dB of noise. This reduction prevents DC currents, caused by the increasing use of asymmetrically loaded devices, from compromising audio fidelity. The unit’s DC-blocker stabilizes the power supply, eliminating hum and heat in sensitive Hifi equipment for optimal sound quality.

Designed with a robust aluminum chassis, the mains block also offers three-way surge protection, shielding connected equipment from high-voltage spikes. The aluminum housing not only adds durability and a sleek finish but also minimizes exposure to electrical and magnetic fields.

Today’s households are dense with noise-generating devices: Wi-Fi, Bluetooth, LED lights, and more. Supra’s NIF technology targets this pervasive noise floor, ensuring a deep, “black” background for enhanced audio dynamics. Achieving such a quiet performance level is rare, and Supra’s innovative, science-based approach enables audio purity without unproven methods.

Configurable Filtering Options

Standard NIF configuration includes:

• Output 1: Non-filtered but surge-protected and DC-blocker (ideal for amplifiers)
• Remaning Outputs: Filtered, surge-protected and DC-blocker

Custom configurations are available, offering filtered or non-filtered outputs tailored to your system.

Key Benefits

• Noise reduction up to 40 dB, improving silence and sound dynamics
• DC-lift (3.6V) to prevent core saturation and heat
• NIF and DC filters effective without protective earth
• Enhanced bass and micro-dynamics from a silent background
• Customizable NIF filter available
• Oxygen-free copper wiring for clean power delivery
• Peak power support up to 3680W @ 230V, 16A
• Surge protection against lightning and high-voltage spikes
• Shielded aluminum chassis prevents external field interference

Important Installation Tips

For maximum filtering benefits, use the Supra LoRad mains cord with protective earth to enhance shielding. While the NIF and DC filters work without protective earth, optimal results require proper grounding to protect and maintain the silence of your Hifi equipment.

Warning: Never ground to water radiators or pipes. Doing so can pose severe electrical hazards in multi-unit buildings.
