DC Blocker

The majority of amplifiers suffer from irritating mechanical transformer hum. The cause? Any incoming mains DC
voltage ranging from 1,000mV to several hundred millivolts.

The DCBlocker is the iFi solution

* Intelligently blocks > 1,000mV DC to eliminate transformer hum
• Safely retains EMI shielding
• Does not affect equipment safety
• Can be used around the globe

What are the credentials of the DC Blocker?

* ZERO DC Block technology blocks incoming DC – up to 1,200mV
* Voltage rating 90 – 240 volts
* Maximum current rating > 10A
* Continuous current rating 7A
* Universal IEC
* Hospital-grade IEC connectors
* Dimensions: 68 x 37 x 32 mm / 2.7” x 1.5” x 1.3”
* Weight: 63g / 2.2oz

Is the circuit in series with the power lines?
Does this limit current in any way?

 

[dan31]

They are going to sell a few of these. Common problem.

Would you please explain how your low noise iPower supply works and is different from other switching supplies and how it betters the Linear power supplies in noise, etc..
I‘m looking to upgrade a 12v and 5v power source. Thank you in advance !

Ah.. more reading and I found this..
”Enjoy clear audio and more defined digital video with the iPower's Active Noise Cancellation, technology derived from military applications that acts similarly to noise cancelling headphones by measuring and inverting the signal from your power supply to create a super quiet noise floor and to filter out spurious frequencies introduced by common household equipment that would interfere or muddy your entertainment experience”

Hi Guys,
I completely missed your questions. Did not get a notification. Not sure why.

The DC Blocker does not limit current. Its sole aim is to block the DC leakage. That is why it does it so well.

@Mikem53
We have installed a separate Anti Noise Cancellation board inside of our iPower and iPowerX. It cleans the noise before it gets rectified into DC. That is the main reason why iPower and iPowerX are so quite. It also gives you more amperage, so that you could drive power-hungry devices. These are what differs iFi power solutions from the other power supplies.

Behind every good component is a DC Blocker.

Great product.

Hey Folks, Just sharing some thoughts from HFChoice on the DC Blocker...

Check out what Hi-Fi Choice thought of the original DC Blocker.

We now also have the New DC Blocker+ available right here...

iFi DC Blocker+ | Reduces transformer hum in Audio Systems

DC Blocker+ reduces transformer hum, particularly in amplifiers using a toroidal transformer, thereby unlocking the sonic potential of your audio systems.

@AMR / iFi audio Can I use DC Blocker with Esoteric Grandioso M1 monoblock amplifier ?

Grandioso M1 | FEATURES | ESOTERIC:Japan high-end audio manufacturer | エソテリック

Pride and Mission of ESOTERIC - The joy of the highest level of musical elation

www.esoteric.jp

It states that "Large bipolar LAPT* transistor components boasting the revolutionary current-supply capacity of 17-ampere continuous action and 34-ampere instantaneous action were adopted for the M1."

Thanks

Folks, just posting some feedback from a customer on his experience with our DC Blocker!

Take a look at what a customer from Glastonbury in the UK said about the DC Blocker, "It works. My Arcam A32 amplifier no longer suffers from transformer hum/buzz at certain times of the day. Brilliant!"

Cheers!!

Just with a first glance I don't see why you couldn't but I would send a quick support message thru our website for absolute confirmation.
If I get any different answer I will post it here as well.

Cheers!!

Folks, Just sharing a review from Stereo Head on the DC Blocker, Enjoy!

https://www.stereo-head.it/2021/04/...tica-ai-problemi-di-alimentazione-recensione/

"IFI’s DC Blocker and GND Defender are two products that take care of the point and solve two problems present in many plants in a direct and immediate way. The cost is not very low, but both work very well and put an end to power problems difficult to solve in my case they immediately eliminated the vibrations of the power amp, a problem that I had been carrying around for a long time, therefore, I found the money spent on the DC blocker the 150 euros best invested in my systems since the buzz was very annoying.”

Thanks to Matteo!

Cheers!!

DC Blocker!
