Tone controls, I know, I know............................

Digitize the problem recordings then tweak them with logic or whatever audio software you use. this seems a much better approach than to degrade your system by adding a tone control.

Hey Ralph, I don't have a cd player yet alone software to tweak, vinyl only.............

Rick,

I think you are on the right track with a low pass filter to take out those offending highs as you posted above.  An RC network that can be cut in and out would work.

The formula is 1/2(Pi)RC; this formula gives the 3dB down point of the filter.  You take a capacitor and pot to ground.  This shunts high frequencies to ground.  The pot should have the center lug (wiper) soldered to one or the other lug.  This makes it a variable resistor, from zero to the full value of the pot.

Does this make sense?  If not I can explain better.

Yahoo!!!!! This is exactly what I am looking for Grainger, something that is easily bypassed except for those really bad pressings!!!!  Gotta go pick up the kids but would love to pick your brain later if I could, thanks !!!!

Hey Grainger, was just yakkin with a buddy of mine who says his Fender amp uses a pott that tuns off ( disengaged) and then turns on, I could use this , ya??

If I understand you correctly, that would do.  Even better if it is a stereo pot to control both channels at the same time.

Hi there, I understand your point, however, its not the system that I have issues with-- its a few bad recordings I would like to make listenable...........  My system consists of the Stereomour with Solen teflon caps in the coupling position and Mundorf Silver Gold and Oil in the output position, Cornscala's with Mundorf  Mcaps in the crossovers ( love these speakers!!!) And the Eros with Mundorf Silver Gold and Oil in the output position.  Love the entire system, best it has ever sounded, its poor recordings I am trying to work around.................. so what I was thinking was some type of rolloff doohicky that I can bypass for 70-75% of my recordings because they sound brilliant but engage if I so desire for the 20-25% of crappy less then stellar recordings....................

Ok, now I'm getting it! Sorry, I didnt know the specifics..Ok - crappy recordings - I can relate on that issue. Much of rock is crappy. Much of my FAVORITE rock is crappy. Here has been my solution from my system standpoint. I have upsampled my redbook to 24/96 using Sox with min. phase filter. This has solved much of the 'crappy recording' digititis. I like redbook as much as native 24/96 when it is upsampled with Sox using min. phase. Sorry, but other upsamplers need not apply. I havent tried Weiss Saracon 1.6 because it costs $1500. Still, better recordings sound better! At least the crappy recordings are enjoyable, and very listenable. Sometimes the remasters are better (Beatles, Floyd, Yes, Rush, etc.).  I appreciate your efforts in your hobby. I can also appreciate your frustrations!

P.S. - love the Mundorfs!

Eric

oops! - Sorry again Rick - Just realized you're a vinyl guy. My bad.

Hey, no worries, I really appreciate all the input guys!!!

It may be possible to make a passive tone control, perhaps with a limited boost capability to maintain enough ain. With the Eros, you probably have ore than enough gain and can spare some for the tone controls. I'll look into it when I am back - you might need to remind me though ...  :^)

Awesome Paul, thanks!!! And , will do!!!

Hey could this work, found this and others on AES..............
