iFi Audio SilentPower AC iPurifier 2 Mains Noise Filter

SilentPower AC iPurifier 2 Mains Noise Filter

Product Description

Silence starts at the socket with the SilentPower AC iPurifier 2, a compact plug-and-play mains conditioning solution designed to reduce electrical noise before it reaches your audio or AV system. Built for high-performance home audio, home theater, and hi-fi setups, the AC iPurifier 2 targets EMI/RFI interference, polarity issues, earthing problems, and sudden power spikes to help your system perform with greater clarity, stability, and silence.

Using patented Active Noise Cancellation III technology, the AC iPurifier 2 reduces mains noise by more than 40dB, or over 100x, compared to standard filtering methods. Inspired by advanced noise-cancellation principles, it detects unwanted interference on the power line and generates an inverted signal to cancel it out. The result is a cleaner power foundation that can reveal improved detail retrieval, a darker background, greater depth, and more refined audio performance.

Unlike traditional power conditioners that may sit directly in the power path, the AC iPurifier 2 operates in a parallel configuration, helping preserve the dynamics and energy of your audio system. Intelligent LED diagnostics make setup simple by identifying polarity and earth issues, while built-in surge protection helps shield valuable components from voltage spikes. For systems affected by hum or buzz, the 4mm supplementary earth port can be paired with the Groundhog+ kit to help channel unwanted noise away from your equipment.

FAQ Section

Q: What does the SilentPower AC iPurifier 2 do?
A: The AC iPurifier 2 is a plug-in mains conditioner that reduces EMI/RFI noise, checks polarity and earth status, provides surge protection, and supports supplementary grounding for audio and AV systems.

Q: How much noise reduction does the AC iPurifier 2 provide?
A: It reduces mains noise by more than 40dB, which equals over 100x noise reduction compared to standard filtering methods.

Q: Will the AC iPurifier 2 affect my audio system’s dynamics?
A: No. It operates in a parallel configuration, so it conditions the mains supply without sitting directly in the power path or compromising system dynamics.

Q: What is Active Noise Cancellation III?
A: Active Noise Cancellation III is SilentPower’s patented technology that detects unwanted EMI/RFI noise on the power line and generates an inverted signal to cancel it.

Q: Does the AC iPurifier 2 include surge protection?
A: Yes. It features built-in surge protection rated at 22,000A @ 1,000V, 8/20uS, helping protect your system from sudden power spikes.

Q: What do the diagnostic LEDs show?
A: The LED indicators help confirm correct operation and can flag polarity or earth issues, making it easier to identify setup problems with your mains supply.

Q: Can the AC iPurifier 2 help with hum or buzz?
A: Yes. When paired with the Groundhog+ kit, the 4mm supplementary earth port can help channel noise away from your system and reduce grounding-related hum or buzz.

Q: What comes in the box?
A: The box includes 1 AC iPurifier 2 and 1 user manual.
