iFi Audio DC Blocker disable hum in amplifier

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

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




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.
