Sayonara Transformer Hum for Pure and Silent Audio

Advanced DC offset filter designed to stop DC voltage from entering your audio components. DC on the AC line can saturate toroidal transformers, causing mechanical hum and reducing clarity. The Filter restores silent operation and sonic purity.

Enhanced Clarity and Dynamics

By preventing transformer saturation, the Filter reduces vibration and noise, improving transparency, focus, and low-level detail in any Hi-Fi setup.

Intelligent and Safe Design

It blocks over 1000–1200 mV of DC without compromising electrical safety and retains EMI/RFI noise suppression for a cleaner signal.

Compact and "Plug-and-Play"

Simply place it at the IEC power inlet. No tools, modifications, or extra setup required. Compatible worldwide (90–250V).
