The iFi Audio AC iPurifier 2 reduces electrical noise and EMI and RFI interference on the AC power line before they reach your audio equipment. Active Noise Cancellation III technology operates in parallel with the power supply and reduces noise by more than 40 dB without restricting the power supplied to the amplifier.

LED indicators for polarity and grounding help you check the power supply and can be switched off. The device features surge protection, a 4 mm auxiliary ground connection and plug-and-play operation: simply connect it directly to a wall outlet or an available socket on a power strip. Multiple units can be used in the same audio system.
