DESCRIPTION
Sayonara mechanical hum.
Mains electricity, crucial to your audio systems, can often be disrupted by various interferences, distorting the AC waveform, and reducing audio quality. ‘DC on the mains’ is a common problem, particularly with amplifiers.
Although household outlets are intended to deliver pure AC power, a range of your home appliances—from lighting controls to home appliances power supplies—create ‘asymmetrical loads’, resulting in DC voltage on the AC supply.
When a small amount of DC voltage from the mains reaches the transformer, it can cause ‘saturation’, leading the transformer to produce a significant and persistent humming sound. You can hear it when you bring your ear close to or next to the chassis.
The DC Blocker+ is a smart device that, when you place it at the IEC (the rear power inlet), prevents DC from getting into the amplifier, thus eliminating transformer hum.
Plus. Protect.
Enjoy music without the annoyance of unwanted hum.
- Intelligently blocks over 1,000mV DC to eliminate transformer hum.
- EMI shielding is retained.
- Equipment safety is unaffected.
The bigger the amplifier, usually, the larger the toroidal transformer — often sensitive to residual DC voltage. Simply add the DC Blocker+ at the IEC to stop DC from getting in.
- Globally compatible (90-250V).
- Designed for high-power equipment (Continuous current rating: 10A).
- Compact design ensures it doesn’t obstruct other connectors, sockets, or cables.
