iFi DC Blocker
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.
All the benefits of cutting out annoying hum with no drawbacks.
- Intelligently stops any DC voltage from the mains to eliminate transformer hum
- EMI shielding is retained
- Equipment safety is unaffected
ZERO DC Block technology – stops DC from getting into your amplifier and eliminates amplifier transformer hum. 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).
EMI shielding is retained.
