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 - room 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.

Optical Galvanic Isolation

The DC Blocker/+ removes such DC and eliminates such mechanical transformer hum, makes the transformer operate at the optimum environment. With the DC Blocker/+, there is 0 DC pass through.

ZERO DC Block Technology

ZERO DC Block technology - stops DC from getting into your amplifier and eliminates amplifier transformer hum.

EMI Shielding

EMI shielding is retained.

High-Performance Semiconductor

High-performance glass passivated semiconductor. High-case dielectric strength of 1500VRMS. UL listed.  Flame resistant IEC socket/connecter/chassis (Fireproof polymers UL94-V0).
