The iFi Audio DC Blocker+ is an essential device for ensuring the best possible audio quality. By preventing the disruption of AC power from various interferences, it allows your audio system to perform at its best. The DC Blocker+ also eliminates transformer hum, which can be a common issue with amplifiers. 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.

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.
With this device, you can rest assured that your audio system is running optimally and that you're getting the most out of your equipment.
Moreover, the iFi Audio DC Blocker+ is very easy to install and use, so you can enjoy better sound quality with minimal effort.
If you hear audible hum inside a powered audio product, especially with a toroidal transformer inside, iFi's DC Blocker+ was designed to either lower or remove that noise.
Insert a DC Blocker+ into the mains input of your equipment at the IEC power inlet. Plug the power cord into the DC Blocker. You can use a DC Blocker on each piece of equipment that has a power transformer in its power supply.
Although the DC Blocker+ unit will still provide switchmode power supplies with power, there is little benefit in doing so. In a switchmode power supply the AC mains is first rectified into DC, after which a high frequency switching regulator circuit takes care of any AC or DC fluctuations on the mains.
The majority of audio electronic equipment uses a power transformer or transformers for their power supply. Mains power starts out being a pure sine wave at the power station but ends up having a lot of distortion imposed upon it by the time it reaches your equipment at home. The distortion comes from other equipment connected to the same power line and could be industrial or domestic in nature, such as pulse-width modulated electric motors (eg. vacuum cleaners, heat pumps), household heating, washing machines, phase-controlled industrial equipment in factories, light dimmers, etc.
The DC Blocker is mainly designed for source equipment and amplifiers with a power transformer rating up to 500W (for 230V) or 350W (for 115V). Using equipment with a higher power rating is ok though, as any more power demanded through the DC Blocker is transferred straight to the equipment. DC blocking will still work, but to a lesser degree.
iFi's DC Blocker was designed not to. If anything, it will improve a connected component’s sound quality due to removal of excess DC voltage.
