AC from the mains is seldom purely 100% AC! That small amount of DC voltage is why transformer hum is exacerbated in the first place. DC saturates the core of the transformer, generating heat and kinetic energy from DC, shaking the trafo and causing audible humming.
@@iFiaudiochannel When measuring DC voltage on the 120vac wall outlets at a house my DVM meter is NOT measuring any DC, any reasons why? There must be a different earth grounding reference or something I'm doing is wrong
Hi James, Seyfi here. Now I’am gonma get this as well as it really makes a difference like the GND. But could the nice guys at IFI come up with a wall outlet friendly one or a multi unit having all for wider studio use with just one unit? So many thanks for the videos, it gives me more confidence when you demo gadget like this at the TSR JiveyTT!👏🏻👏🏻👋🏼👋🏼🧿
I hope the DC Blocker works well for you! We'll certainly think about combining them. Some people may have one issue or the other - as they're unrelated - which is why they are currently separate units.
Cool! Now, how do I stop my guitar picking up my computer fan or whatever that noise is? Depending on how I turn, the noise goes away. Could this be the same issue like you're showing in the video? I'm experiencing this when recoding onto my computer, no amp.
@@nedim_guitar I don’t think this is the issue I’m describing here. I’m guessing your guitar has single coil pickups? Maybe worth checking the cable you are using and check that your computer is properly grounded/earthed.
@MulletTrain-o2g Yeah, sounds about right. Now, if there was something we could do about it... Maybe putting the computer in another room? We'll see...
Will have to give credit where due to the manufacturer for whomever they were able succesdfully dupe into paying $129 for a product that cost $25 to $35.
Why would an AC output from the wall outlets have a DC voltage/DC current that is causing HUM? that doesn't make sense at all

Brilliant! Thanks.
cool, but peoole dont use amps anymore, do this works with modelers too?
Great idea!
This is exactly what I want for Christmas. Thank you James for this usefull video! 👍 Sorry Maria Carey, but this is what I want for Christmas 😂

@@TSR-JiveyTalksTech The cable is ok, it just might be an annoying ground issue. Thanks Jivey!

100%, its two diodes, and a capacitor. 1€ in parts
Make them yourself and charge $2. 100% mark up so you should do well.
@@ERMAV you do it!
Hmm something is a little bit off here... most DC blocker`s contain large electrolytic caps... cant see this mini gadget will work.
it helps if you sit away from the amp more and it helps if you use humbuckers or noiseless Strat coils or more shielding....
Most might! Our DC Blocker still blocks up to 1.2V of DC on the AC-and works up to 7A!

It's a bit rich for me! Good idea though.
129$?!
I'm noy paying $129

it annoys me so much when its so obvious that the talking head is reading a script
Well spotted, I was reading from an Auto-cue. I'm sure you wouldn't want me making any technical errors on such technical subject would you?
