DC Blocker

Got big amplifier. Bye bye mechanical hum.
Many large amplifiers have a really annoying mechanical hum (emitted from the toroidal transformer itself).

You can hear it when you place your ear close or next to the chassis.

This is caused by a small amount of DC voltage in the mains which makes its way through to the mains transformer, it will become ‘saturated’ and start to hum like a trooper.

The DC Blocker is a clever device that you place at the IEC (at the rear power inlet) and as its name implies, it stops DC from getting into the amplifier. It therefore eliminates amplifier transformer hum.




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

EMI shielding is retained.

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.

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