SilentPower DC Blocker+

IFi SilentPower DC Blocker+ — The hum-eliminating solution

Unpleasant mechanical hum from the transformer can be a problem that disrupts your music listening or AV system. The iFi SilentPower DC Blocker+ specializes in eliminating unwanted DC voltage at the amplifier input, effectively reducing hum and improving sound quality. With support for 10A continuous current and global voltage compatibility of 90-250V, this blocker is the ideal solution even for higher-powered devices.

DC voltage blocking for cleaner sound

Mechanical hum is often the result of the presence of a small amount of DC voltage in the mains transformer. The DC Blocker+ eliminates this voltage, protecting the amplifier and ensuring clean, undisturbed sound. ZERO DC Block technology prevents DC current from entering and ensures that the amplifier transformer does not resonate unpleasantly. The result? A quiet and authentic listening environment.

Safety, durability and compatibility

DC Blocker+ is designed with safety and durability in mind. It features a 1500V RMS dielectric strength enclosure, flame-retardant IEC connectors and a chassis made of UL94-V0 flame-retardant polymers. Thanks to its compact dimensions (68 x 32 x 37 mm), it takes up almost no space and is universally compatible with various audio and AV systems. In addition, it does not block any other connectors or wiring, which will be appreciated by users with limited space.

Improve power quality

Mains electricity is crucial for the performance of audio systems, but it is often disrupted by interference and distortion of the AC wave. DC Blocker+ eliminates these problems and ensures that your equipment receives clean and stable AC power. This improves overall sound quality and minimizes mechanical noise.
