Supra LoRad MD01-16-AUS/NZ – DC Blocker for Clean, Efficient Power
The SUPRA LoRad MD01 is an advanced DC blocker designed to eliminate unwanted DC voltage from AC power, ensuring clean, efficient power for sensitive audio and multimedia equipment. In today’s households, DC interference from modern appliances can disrupt the ideal sine wave of AC power, reducing efficiency and causing issues like transformer hum and excess heat. By filtering up to 3.6V of DC offset, this unit prevents iron core saturation and improves transformer performance, extending equipment life and enhancing sound clarity.
Easy to integrate into any existing power setup, the DC-blocker does not require a protective ground, although grounding is recommended for additional RFI shielding. Engineered to improve audio purity, it reduces extraneous noise without compromising dynamics. Listeners often notice clearer, tighter bass and reduced harshness, allowing the full depth and detail of recordings to shine through.
Key Benefits:
- Eliminates DC offset: Reduces transformer hum and excess heat, enhancing equipment life
- Improves sound clarity: Achieves a quieter noise floor and sharper, more distinct bass
- No loss in dynamics: Maintains true audio dynamics for a cleaner, more immersive sound
- Filters up to 3.6V DC: Future-proofed to handle next-gen electrical demands
- Made in Sweden: Precision-built to Supra Cables’ “No-Nonsense” standard, balancing performance and affordability
Rated for 16A and 3,680W peak power, the DC-blocker works best with a SUPRA LoRad mains cord, optimizing its filtering capability. Connect and disconnect carefully following the recommended procedure to prevent any residual charge in connected devices.
Elevate your audio experience with SUPRA's innovative, high-performance DC-blocker, and enjoy a cleaner, more authentic sound.
It is rated 16 Amp and allows for 3,680 Watt of peak power. The connection cord is optional, we recommend our SUPRA Lorad Mains Cord rated 16 Ampere for optimal operation. (the DC-blocker input is a C:19 IEC 320 rated 16 Amp)

Really has helped the clarity of the separation of instruments hearing parts of music I could not hear before the owner Mark was so convinced I would hear the difference and if I didn’t he would refund the cost what have you got to lose
