iFi audio SilentPower DC Blocker+ Power Cable

The iFi audio SilentPower DC Blocker+ is a compact DC offset filter that plugs into the IEC inlet of any amplifier or DAC to stop residual DC voltage from contaminating the AC mains supply. It eliminates the mechanical transformer hum that toroidal transformers produce when DC rides on top of the AC line, restoring silent, clean playback. With hospital-grade IEC connectors, a 10A continuous current rating, and universal 90–250V compatibility, it handles high-power amplifiers up to 2200W on 220V mains. Installation is as simple as plugging it in between the existing IEC power cable and the equipment.

• ZERO DC Block technology intelligently blocks up to 1,200mV of incoming DC offset to silence transformer hum
• Hospital-grade IEC connectors with fireproof UL94-V0 polymer chassis and 1500VRMS dielectric strength
• Globally compatible 90–250V operation with 10A continuous / 14A maximum current rating
• Compact 80 g in-line adapter that fits behind any component without blocking adjacent sockets
