Home audio & video forum: Filter to remove hiss an pops from turntable.

Thanks for the reply Bob. I used the term filter which was a little misleading. It was a sporadic frequency dampener rather than a a constant filter.

take a look for Burwen here. Good luck.

But this old tech is now hard to find as folk run the content through a PC to digitize and use software to remove or soften the pops.

I recall folk were seeking Nirvana on this. While those did a fair job, the usual audio nut was looking for something that would absolutely remove it without impacting any other quality.

Even today you'll see such requests.

But I see the Burwen is documented well enough that your more tenacious folk will build their own.

Thanks for the reply. You are absolutely correct about wow and flutter being associated with speed variations of belt drive turntables, not so much with direct drive units. The issue I am trying to address is caused by imperfections in the Vinyl. Some times this was caused by less than perfect pressings. Sometimes due to needle erosion and mishandling etc. This produces instantaneous spurious noise. The Burwen may do the trick. It does seem to dampen rather than eliminate... That is what you want to do so it does not produce gaps. Thanks so much again I enjoy being part of this forum..
