DC Blocker by iFi Audio – Part of SilentPower by iFi
Got big amplifier? Say goodbye to mechanical hum. The iFi Audio DC Blocker is the perfect solution for eliminating the annoying hum from your amplifier’s toroidal transformer. This hum, caused by small amounts of DC voltage in the mains, can saturate your amplifier’s transformer and disrupt your listening experience. The DC Blocker stops DC from entering the amplifier, ensuring smooth, hum-free operation.
Eliminate Transformer Hum – ZERO DC Pass Through
The DC Blocker is a compact and clever device that attaches to the IEC power inlet of your amplifier. It intelligently blocks DC voltage from reaching the transformer, eliminating the hum and ensuring your equipment performs at its best.
- Eliminates transformer hum caused by DC voltage in the mains.
- Retains EMI shielding to maintain high sound quality.
- Maintains equipment safety – no impact on your system’s protection.
Universal Application for All Amplifiers
Whether you have a large amplifier or a smaller system, the DC Blocker fits seamlessly into your setup. It supports voltages between 90-240V with a maximum rating of 7A and continuous current rating of 4A. Its small size ensures it won’t obstruct any connectors or cables.
- Compatible with all amplifiers and systems with an IEC power input.
