What customers say
This DC blocker earns high praise, especially from audiophiles battling disruptive transformer hum caused by mains DC offset. Users consistently report its primary function is exceptionally effective, delivering instantaneous silence by drastically reducing audible buzzing from high current amplifiers. This noise floor reduction unlocks secondary sonic improvements, including better dynamics and clearer soundstaging, suggesting optimal equipment performance. Build quality is universally lauded, reflecting robust, premium construction. While a significant investment, those suffering from severe DC contamination consider this an essential, transformative component. For systems plagued by DC noise, the Syncro Uni offers a highly effective and necessary solution, justifying its premium cost through tangible performance gains.
Know before you buy
This unit acts as a DC blocker, removing unwanted direct current from your AC mains power. By eliminating this interference, it helps stop mechanical transformer hum and reduces background distortion, resulting in a cleaner, more refined sound.
If you notice an audible buzzing or humming sound coming directly from your amplifier or power supply chassis, it is often caused by DC offset on your power line. The Syncro Uni is specifically engineered to resolve this issue.
No, it is designed to work alongside your current power conditioning setup. You can place the Syncro Uni between your wall outlet and your power conditioner, or directly before a specific component, to provide targeted DC filtration.
You should select the connector that matches the power inlet on your specific audio component. The Syncro Uni is available in C15, C19, and C7 configurations to ensure it fits the standard power inputs found on most high-end amplifiers and source devices.
The unit is designed to maintain high-current delivery while filtering out the DC component. It does not limit the power flow, so it remains suitable for use with high-performance power amplifiers that require significant current.
