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.
Primary Use: Reduces mains noise, EMI/RFI interference, polarity issues, earthing issues, and power spikes before they reach an audio or AV system
Noise Reduction: >40dB, over 100x reduction
Noise-Cancellation Technology: Patented Active Noise Cancellation III
Filtering Method: Parallel configuration for clean power delivery without detrimental effect to system dynamics
Diagnostics: Polarity and earth diagnostic LED indicators
Surge Protection: Built-in surge protection
Surge Protection Rating: 22,000A @ 1,000V, 8/20uS
Supplementary Earth Connection: 4mm port for use with the Groundhog+ kit
Operating Voltage: 90-265V AC
USA Size and Weight: 127 x 40 x 40mm; 127g
Included Accessories: 1x AC iPurifier 2, 1x user manual
Warranty Period: 12 months
