@JohnH & @Gene Ballzz : you should be proud of what you have done. When the internet was first invented this is the sort of things that people (and me!) hoped for it.
I had a look at the other thread, but only a few pages of it, and admire johnh’s engineering work, and Gene’s hands on application.
I just bought a DSL1CR. It is already very nice at low volumes, but I will soon try a volume box in the effects loop (cheap build). If that fails, or regardless of that, this attenuator build sounds exciting, even if I am not great with a soldering iron.
I have a question, and maybe John already replied on the other post - which I will read through the next days / weeks. Why the -7 dB reactive and the rest resistive? And would there be other higher attenuation reactive first step possible build?
My interest is apartment playing, so practical volumes are 65-75 dB (I know, that is very low), and I’d like to crunch the clean channel of the dsl1.
Once again, brilliant work on this. So kind of you!
By design, the reactive -7db stage is always on and active and it provides all the reactive function for all the rest of the stages! In other words, when that reactive -7db stage is in circuit, all the other stages are also reactive. @JohnH can explain it better, but generally -7db is the "sweet spot" in the maths for all the other stages to be in even increments.
