DC Blocker+

Sayonara mechanical hum.

Say goodbye to transformer hum and enjoy a pure audio experience with the DC Blocker+. This advanced DC offset filter is engineered to eliminate unwanted noise and interference, making it essential for high-fidelity audio systems. With the DC Blocker+, your amplifiers and DACs can perform without interference, delivering pristine sound clarity. Its durable design and easy installation make it the ideal upgrade for audiophiles seeking to maximize their equipment’s performance. Enjoy quiet, uninterrupted listening with the DC Blocker+—the ultimate solution for eliminating DC offset noise.

The DC Blocker+ is a smart device that, when you place it at the IEC (the rear power inlet), prevents DC from getting into the amplifier, thus eliminating transformer hum.

Key Features

High-Performance Semiconductor

High-case dielectric strength of 1500VRMS. UL listed.  Flame resistant IEC socket/connecter/chassis (Fireproof polymers UL94-V0).

ZERO DC Block Technology

ZERO DC Block technology – stops DC from getting into your amplifier and eliminates amplifier transformer hum.

High Power Equipment

The DC Blocker + is Designed for high-power equipment (continuous current rating: 10A).


Plus. Protect.

Enjoy music without the annoyance of unwanted hum.
  • Intelligently blocks over 1,000mV DC to eliminate transformer hum.
  • EMI shielding is retained.
  • Equipment safety is unaffected.

Plus for Higher Power Equipment.
The bigger the amplifier, usually, the larger the toroidal transformer — often sensitive to residual DC voltage. Simply add the DC Blocker+ at the IEC to stop DC from getting in.
  • Globally compatible (90-250V).
  • Designed for high-power equipment (Continuous current rating: 10A).
  • Compact design ensures it doesn’t obstruct other connectors, sockets, or cables.

How do I use?
