  • iFi Audio DC Blocker+ - Refurbished

    Refurbished unit in excellent condition repackaged with original accessories or accessories from compatible models and brands. All refurbished products are certified by authorized technicians.

    The iFi Audio DC Blocker+ enhances the quality of AC electricity for your audio and AV systems. Mains electricity, crucial to your audio systems, can often be disrupted by various interferences, distorting the AC waveform, and reducing audio quality. ‘DC on the mains’ is a common problem, particularly with amplifiers.

    The majority of audio components will have a circular, toroidal transformer at their heart. These transformers are excellent but have one major drawback. Any incoming mains DC, which can range from 1,000mV to several hundred millivolts, will cause an annoying 'mechanical hum'.

    Just as you are listening to the quietest of tracks, your ears pick up an annoying low-level hum from inside your audio component. Place the DC Blocker+ at the IEC inlet of the audio component to stop DC from entering it and causing 'hum'. Install one at the incoming mains of each and every audio component to ensure a tranquil, 'hum' free listening experience.

    Plus. Protect.
    Enjoy music without the annoyance of unwanted hum. Intelligently blocks over 1,000mV DC to eliminate transformer hum. EMI shielding is retained, and equipment safety is unaffected. If you have a mechanical hum, deploy the DC Blocker+.

    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.

    Smart Device
    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.
