iFi DC Blocker+ logo

Enhances the quality of AC electricity for your audio and AV systems.

If you have a mechanical hum, deploy the DC Blocker+

iFi DC Blocker+

Sayonara mechanical hum.

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.

Although household outlets are intended to deliver pure AC power, a range of your home appliances—from lighting controls to home appliances power supplies—create ‘asymmetrical loads’, resulting in DC voltage on the AC supply.

When a small amount of DC voltage from the mains reaches the transformer, it can cause ‘saturation’, leading the transformer to produce a significant and persistent humming sound. You can hear it when you bring your ear close to or next to the chassis.

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.

iFi audio DC Blocker+

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.
