Key Features & Technology
- ZERO DC Block Technology: Automatically cancels up to 1,200mV of DC voltage before it reaches your equipment. This stops the transformer core from becoming magnetically saturated and buzzing.
- High-Power Handling: Features a 10A continuous current rating and up to a 14A maximum rating, making it safe for power-hungry amplifiers.
- Inline Design: Connects directly to the standard rectangular IEC power inlet on the back of your audio component. Your existing power cable plugs straight into the back of it, removing the need for extra cables or shelf space.
- Preserves Shielding & Safety: Retains complete EMI shielding and uses a fireproof, UL94-V0 rated polymer chassis to guarantee equipment safety is unaffected.
You should consider the DC Blocker+ if you hear a low, steady mechanical buzz coming directly from the physical chassis of your amplifier or power supply (not from your speakers). This is typically caused by large household appliances (like refrigerators, hair dryers, or dimmers) polluting your shared home electrical grid and causing an asymmetrical AC waveform.
