Absorption of digital hash


Berkeley uses material to absorb stray digital noise. Anyone know what they use?

I just don't believe you can slap a little bit of some 'magic' material to tackle emissions. EMC compliance (includes RFI/EMI emissions) is big business in Europe and companies spend millions to ensure their products meet the requirements at all stages of product development.  At the design stage you account for emissions and you control them using various design techniques. Then there are several stages of EMC testing before a product is released to production.

If you believe you have emissions issues you need to measure it and then decide what to do about it. I am assuming that you mean emissions when you say stray digital noise. What do you think is the root of it, where is it coming from?

 

+1 on shungite, @mahgister is right

 

Why did you say that ?

How dare you ?😉

 

Please explain a bit why if i am right ?

If not this one line did not say much... 😁

Thanks ...

I put shungite between tubes and tranformers on my Wavac EC300b as well as on top of all my power supply transformers. Clarity and Impulse!

Thanks it is good to know for anyone...

 

Now try some quartz or herkimer diamond near the shungite or in his place at some point to reach an even better balance ...Experiment and listen to aim at the right balance and spots...

Shungite tend to compress sound ... ( it shield from EMI too )

Quartz tend to decompress it ...

balance is key ...

@ptss That plate is Permalloy. It has magnetic properties similar to Mu metal but is much less ductile. Mu metal can be formed easily into various shapes. 

I have digital equipment all around analog gear and I don't have to shield anything. I do not have any interference or mystery noise. I spend my money on records and not trying to fix problems I do not have. The solution is not to buy equipment that is inadequately shielded.
