iFi DC Blocker+ \u2013 Blocking DC Current<\/strong><\/h1>\n

The iFi DC Blocker+<\/strong> resolves the hum issue<\/strong> in audio systems.<\/p>\n

The iFi DC Blocker+<\/strong> from the SilentPower<\/strong> line by the British manufacturer is an intelligent device that, when placed at the IEC power input<\/strong> (the rear power socket), prevents DC current<\/strong> from entering the amplifier, eliminating the annoying transformer hum<\/strong>. Thanks to the DC Blocker+<\/strong>, you can finally enjoy a disturbance-free listening experience<\/strong>, fully immersing yourself in the music.<\/p>\n

The Role of Household Power in Audio Systems<\/strong><\/h3>\n

Household electricity, a fundamental element for audio systems, is often subject to various interferences<\/strong> that distort the AC waveform<\/strong>, compromising audio quality<\/strong>. One of the most common problems, especially with amplifiers, is the presence of DC current<\/strong> on the electrical grid.<\/p>\n

Although household sockets are supposed to provide pure alternating current (AC)<\/strong>, several household appliances\u2014from lighting controls<\/strong> to power supplies<\/strong>\u2014create asymmetric loads<\/strong>, which can lead to DC voltage<\/strong> appearing on the AC network.<\/p>\n

How the iFi DC Blocker+ Works<\/strong><\/h3>\n

When even a small amount of DC voltage<\/strong> reaches the amplifier\u2019s transformer<\/strong>, it can cause saturation<\/strong>, leading to a significant and persistent hum<\/strong>. This hum is easily noticeable by placing your ear near the amplifier\u2019s chassis<\/strong>, especially in high-powered amplifiers<\/strong> equipped with large toroidal transformers<\/strong>, such as those from Hegel<\/strong>.<\/p>\n

This is where the iFi DC Blocker+<\/strong> comes into play.<\/p>\n

The DC Blocker+<\/strong> is a smart device<\/strong> designed to eliminate transformer hum<\/strong> in power amplifiers<\/strong>. Positioned at the IEC power input<\/strong>, it intercepts and neutralizes DC voltage<\/strong> before it reaches the amplifier<\/strong>, protecting it from potential damage<\/strong>.<\/p>\n

Thanks to ZERO DC Block technology<\/strong>, the device completely blocks DC interference<\/strong>, ensuring a clean and disturbance-free listening experience<\/strong>. Designed to handle high-power equipment<\/strong> (nominal continuous current: 10A<\/strong>), the DC Blocker+ is compatible with a wide range of amplifiers, including those featuring large toroidal transformers<\/strong>, which are particularly sensitive to DC voltage<\/strong>.<\/p>\n

Key Features<\/strong><\/h3>\n
    \n
  • Compact Design<\/strong>: Easily integrates into any audio system without interfering with connectors or cables.<\/li>\n
  • Safety<\/strong>: Preserves the EMI shielding<\/strong> of the equipment without compromising security.<\/li>\n
  • Effectiveness<\/strong>: Blocks over 1000mV of DC<\/strong>, completely eliminating transformer hum.<\/li>\n
  • Versatility<\/strong>: Global compatibility (90-250V)<\/strong>.<\/li>\n<\/ul>\n

    How to Use<\/strong><\/h3>\n
      \n
    1. Connect the male IEC plug<\/strong> of the DC Blocker+<\/strong> to the power input of your device.<\/li>\n
    2. Insert the original IEC power cable<\/strong> of the device into the female connection<\/strong> of the DC Blocker+<\/strong>.<\/li>\n<\/ol>\n

      Conclusion<\/strong><\/h3>\n

      The DC Blocker+<\/strong> is the perfect solution<\/strong> for those who seek a disturbance-free listening experience<\/strong> while protecting their amplifier from potential damage<\/strong> caused by DC voltage<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"

      The iFi DC Blocker+<\/strong> is a compact device<\/strong> that connects directly to the IEC power socket<\/strong> of your audio component.
