Simple Anti RIAA pre-filter

[Ganzha]

Here is very simple Anti RIAA pre filter shematics diagramm

[studiorp]

For anti riaa, you mean inverse riaa ?

[Ganzha]

Sure - this is for ajusting phono preamp

[stanislav]

it probably is not suitable, I think ...

[Steve E.]

anyone else care to weigh in??

You need Inverse RIAA curve to cut discs, the opposite RIAA replay is used for replay.

Get one here http://www.hagtech.com/iriaa2.html

Or if you are cheap like me buy the resistors, capacitors and phono plugs sticking in your own case.

This is a passive filter, introduces a very large loss in the audio track, you need to apply any much more efficient Including a silencer high frequency above 17kHz, for example, such as the processor is active filtrNeumann sab74b/vg easy to zmajstrowania, almost perfect!

Well was only trying to help I for one do not have Neumann money or a Neumann system and if you wanted to make this active that is no big deal.

I thought this was designed to go fairly early in your cutting chain i.e. on mixer bus out or line amp which then feeds your cutting amp to which you monitor output level to ensure you do not kill your head. The only other items you need are a compressor and de-esser which goes at the end of the chain to cut those frequencies over 10kHz again so you do not kill your head. Essentially you need two chains one to monitor signal and one for the cutting chain which includes feedback if you have a feedback cutter head.

This can be done many ways.

I found a riaa plug in for free on a site called http://www.kvraudio.com/,it also has inverted riaa eq included,I've used it with good results.
