Power Purification for HiFi Audiohis DC blocker and AC filter board is designed to eliminate DC offset and power line noise from your mains AC supply. Ideal for HiFi amplifiers and DACs, it ensures cleaner power delivery and improved sound clarity.⚙️ Dual-Stage Filtering CircuitCombines a DC blocking circuit (diodes + capacitors) with an SQ flat-wire inductor EMI filter. Suppresses ripple, static current spikes, and magnetic saturation in transformers caused by unwanted DCcomponents.🔄 High-Performance SQ Inductor DesignThe flat-wire SQ inductor delivers over 1.3× the current density of traditional round copper wire. Closed magnetic path reduces EMI leakage and enhances consistency and insulation, extending your power system's lifespan.💡 Durable Build, Wide Voltage SupportBuilt with a 1.6mm thick fiberglass PCB (dual-sided, black oil, tin-plated), supporting 110–265VAC input, up to 2000W power, and 15A current. Easy wire-in or plug-in installation options iincluded🎵 Reliable Audio Upgrade ModulePerfect for eliminating buzzing or hum caused by AC interference. Whether you're powering a high-end stereo or studio equipment, this board delivers clean, stable power to protect your gear andenhance performance
