iFi SilentPower USB iPurifier Pro USB Noise Filter with Galvanic Isolation

Description Technical Specifications Shipping Reviews USB power circuitry can all too often become a lightning-rod for high frequency EMI and RFI, raising the noise floor and disrupting the clarity of the audio signal across all frequencies.  Following the lead from our wildly popular iSilencer range, the USB iPurifier Pro incorporates our Active Noise Cancellation (ANC) technology into the USB power circuitry. Much like ANC headphones, the USB iPurifier Pro duplicates the unwanted noise and inverts the phase. The two signals cancel one another, leaving you with clean, noise-free USB power feeding into your audio system.  For the most dedicated purists, we also include an external USB-C power input, allowing users to connect a low-noise 5V external power supply. When the dedicated port is in use, the circuitry receiving USB power from the source device is disabled, and only data is received, while power to both USB output ports is handled by the external power supply.  Product Availability Available (current model) Product Type Accessory - Noise/Hum/Signal Power Regulator Style/Type Portable Input Connectivity Options USB Type-B (USB-B) [Data/Audio Signal], USB Type-C (USB-C) [Charging], USB Type-C (USB-C) [Data/Audio Signal] Output Connectivity Options USB Type-A (Full sized) [Data/Audio Signal] Product Dimensions 42.8 x 23.2 x 96mm (1.69 x 0.91 x 3.78 inches) Product Weight (g) 108 Colour Grey Warranty 1 year warranty (local) If you're based in Singapore,  spend $300 or more for free doorstep delivery1.($250 for Silver/Gold/Platinum VIP members) add a few more bucks, for delivery during the night/weekend, or quicker prioritised delivery options2. self-collection is possible at our Showroom, based in Ubi (nearest to MacPherson MRT).
