Hello,

I would like to add a 3 or 4 band EQ section to my pre amp, possibly at the input rather than output.
Ideally this EQ needs to do this (for each band): +6/-26dB
Is it possible to do this without deteriorating the sound quality?
Possible to make a passive EQ and have the 0db position offset by 6db down (if you get what I mean)?

What is the best way to implement this EQ?

Is this where VCA or autoformer can be used?


Thank you,
Herman

This question begs for opinions.

One opinion would be that any EQ will deteriorate the sound quality.

In particular -26dB.

What are you trying to compensate for?

>>What are you trying to compensate for?

I will use this attenuation to almost completely cut a certain freq band. This is not normally used for listening music but quite often for mixing tracks and transitioning from one to another track.

I am looking for (if not the perfect solution) the least compromised implementation of this +6/-26dB EQ capability. Can you specify the type of a circuit that would be of least deterioration to the signal path?

Well, I've stated what I wanted to but here is something you can consider:

Guitar tone stack calculator.

Play with the values and see the results.

I think this is the best you are going to find...but that is just MHO:

Happy toning.

🙂
