Supra LoRad MD07DC-EU/SP with USB socket – Shielded Power Block
with Surge Protection, DC Blocker, and High-Speed USB Charging

The Supra LoRad MD07DC-EU/SP USB mains block offers advanced shielding, noise filtration, and protection from surges and DC currents, alongside fast, safe USB charging. Its NIF (Non-Intrusive Filtering) and DC-blocker technology, developed with Ben Duncan Research (UK), reduces high-frequency noise by up to 40 dB, preventing DC currents from compromising audio fidelity and enhancing Hifi performance. The DC-blocker stabilizes power, eliminating hum and heat in sensitive equipment for optimal sound quality.

Flexible Filtering Options: Designed for specialized setups, this model offers one unfiltered socket, ideal for amplifiers, while the remaining sockets are filtered to enhance overall noise reduction. Custom configurations are available to suit specific needs.

Now equipped with High-Speed USB Charging ports—Type-A (Quick Charge 3.0) and Type-C (Power Delivery 3.0)—this mains block delivers up to 20W, charging devices up to three times faster than standard PC ports. The circuit is safeguarded against overloads and short circuits, resetting automatically when any faulty cable or device is removed.

Configurable Filtering Options

Standard NIF configuration includes:

• Output 1 & 2: 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.

USB Charging Specifications

• Input: 100-240V, 50/60Hz, 0.5A
• Output: 5-12V DC, max 20W
  • 5V / 3A
  • 9V / 2.22A
  • 12V / 1.67A

The Supra LoRad mains block also features a durable aluminum chassis for shielding against electric, electromagnetic, and magnetic fields, preventing interference with Hifi equipment and maintaining a silent, dynamic audio background.

Key Benefits

• Noise reduction up to 40 dB for deeper silence and clarity
• DC-lift (3.6V) to prevent core saturation and excess heat
• NIF and DC filters effective without protective earth
• Enhanced sound dynamics with distinct bass and clarity
• Customizable NIF filter available
• Oxygen-free copper wiring for clean power delivery
• Peak power support up to 3680W @ 230V, 16A
• Three-way surge protection against high-voltage spikes
• High-speed USB-A and USB-C charging with Quick Charge 3.0 and Power Delivery 3.0 technology
• Shielded aluminum chassis minimizes external field interference

Important Installation Tips

For maximum filter performance, use the Supra LoRad mains cord with protective earth. While NIF and DC filters operate without grounding, proper grounding optimizes filtering and preserves your Hifi equipment’s silence.

Warning: Never ground to water radiators or pipes, as this can create severe electrical hazards in shared buildings.
