Solving the Annoying Mechanical Hum Many large amplifiers suffer from an irritating mechanical hum, typically emitted from their toroidal transformers. This audible hum becomes apparent when you place your ear in close proximity to the amplifier's chassis. The root cause of this inconvenience is the presence of a small amount of direct current (DC) voltage in the mains power supply. This DC voltage finds its way into the mains transformer, causing it to become "saturated" and generate the audible hum that can be quite bothersome.

The Solution: iFi Audio DC Blocker The iFi Audio DC Blocker is a clever and effective device designed to address this issue. It is placed at the IEC (rear power inlet) of the amplifier, where it serves its purpose precisely as its name suggests—it blocks DC voltage from entering the amplifier. By doing so, it eliminates the transformer hum that can otherwise detract from the audio experience.

In essence, the DC Blocker acts as a gatekeeper, preventing any unwanted DC voltage from contaminating the mains transformer of the amplifier. This simple yet ingenious solution ensures that your amplifier operates silently, free from the mechanical hum caused by DC interference.

  • DC Voltage Elimination: The DC Blocker is designed to intelligently prevent any DC voltage from entering your amplifier, making it particularly valuable for larger amplifiers with vulnerable toroidal transformers.
  • Universal Application: With a wide voltage range of 90-240V and a maximum rating exceeding 10A, the DC Blocker is highly versatile and suitable for a variety of applications.
  • Safety First: The DC Blocker prioritizes equipment safety. Its design ensures that EMI shielding is maintained, and it does not interfere with other connectors, sockets, or cables, providing peace of mind.
  • Zero DC Block Technology: Equipped with advanced Zero DC Block technology, this device effectively halts the entry of DC voltage into your amplifier, eliminating transformer hum and ensuring pure audio performance.
  • High-Performance Components: The DC Blocker features high-performance glass passivated semiconductors with a high-case dielectric strength of 1500VRMS. It is UL listed and incorporates flame-resistant materials, enhancing safety and reliability.
  • Compact Design: Its compact size, along with a flame-resistant IEC socket/connecter/chassis, ensures a universal fit without obstructing other connections, making it a practical addition to your setup.
