DC Blocker
SKU: 03-06-041-0001-00
Got big amplifier. Bye bye mechanical hum.
Key Features Explained
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.
EMI Shielding
EMI shielding is retained.
Signal Regeneration
High-performance glass passivated semiconductor. High-case dielectric strength of 1500VRMS. UL listed. Flame resistant IEC socket/connecter/chassis (Fireproof polymers UL94-V0).
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.
Cute. Clever.
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
How do I use?
DC Blocker
Plug the DC Blocker into the back of your amplifier to stop DC from the mains causing transformer hum, in addition to retaining EMI shielding at the power source
SilentPower Reviews
★★★★★"With the iPower2 the noise disappeared completely with the volume at maximum! That silence is what I expected. I heard the music better! The ZEN Air phono with the addition of the iPower2 goes from being a surprising device for the price, to being surprising for its performance"
Guido Ruiz Barría, Surcos de Jazz
★★★★★The iPower X fever-level transformers introduced this time provide the purest DC power supply equipment. Power supply, iPower X is an AC / DC transformer with extremely low noise. Its small volume is filled with a lot of ifi Audio’s exclusive technologies and fever materials
My HiEND Magazine
★★★★★I believe it is a great everyday carry accessory not only for sensitive IEM/Headphone users but also for beefy headphone amplifier owners who would like to hook up their IEMs to these amps and crank the volume as far as they can. The iEMatch 4.4mm gets the highest recommendation I can give to an audio accessory.

★★★★★"This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life"
