iFi Audio SilentPower AC iPurifier 2

iFi Audio SilentPower AC iPurifier 2 - Clean, Shielded, and Silent Power Foundation
Every high-end audio and video system relies on a clean electrical baseline. Unfortunately, standard mains power is heavily contaminated by electromagnetic interference (EMI) and radio frequency interference (RFI) caused by household electronics, appliances, and wireless networks.

The iFi Audio AC iPurifier 2 (by SilentPower) acts as an intelligent, plug-and-play firewall for your system, actively neutralizing noise and earthing issues right at your wall outlet. Running in a specialized parallel configuration, it cleanses your power supply without restricting current delivery or softening the dynamics of your audio. The result is a rock-solid power foundation that reveals greater depth, ink-black silence, and pristine clarity.

User Manual

Active Noise Cancellation III: Drops line noise by 100x to reveal hidden musical details
While conventional power conditioners rely on passive filtration systems that can bottleneck your system's performance, the AC iPurifier 2 features iFi's upgraded Active Noise Cancellation III (ANC III) technology. Inspired by advanced radar defense concepts, this circuit targets EMI/RFI on the power line and generates an inverted signal to instantly cancel it.

This process drops measured noise by an impressive 40dB—a 100x reduction compared to standard filtering methods. By isolating your gear from household electrical interference, it creates an unprecedentedly quiet musical background that reveals rich micro-details and textures in your favorite music.

Heavy-Duty Surge Protection: Absorbs up to 22,000 Amps to shield your expensive gear from voltage spikes
The AC iPurifier 2 features a built-in surge protector designed to shield your most valued components proactively at the source.

Capable of withstanding sudden voltage spikes and catastrophic power surges up to 22,000 Amps at 1,000 Volts (8/20uS), it safely absorbs the impact to protect your delicate electronics from grid instability and lightning strikes.

Smart Diagnostic LEDs: Instantly verifies outlet wiring and polarity for an optimized system setup
Unlike standard conditioners that only filter noise, the AC iPurifier 2 functions as a real-time diagnostic tool for your mains supply.

Its intelligent LED indicator system automatically detects single-phase wiring to confirm your outlet's configuration. The status lights instantly verify whether your system has correct mains polarity and a proper ground status, flagging any wiring issues immediately for fast, effortless troubleshooting.

Integrated 4mm Earth Port: Eradicates frustrating ground-loop hum for a perfectly silent background
If you notice a frustrating hum or buzz coming from your speakers that fades whenever you touch your chassis, your system is likely fighting a grounding issue.

The AC iPurifier 2 is equipped with a dedicated 4mm supplementary earth port. When paired with an optional grounding kit (like the Groundhog+), it provides an independent, secure path to channel stray noise safely away from your system, anchoring your entire AV chain into a stable, hum-free foundation.
