“I wish I understood his statement better.. but it implies to me that if we can use other processing to “assume 125% peaks” with lower priced gear, then we accomplish the advantage of the 222. Is my assuming comprehension is correct?”
I think yes and no, from my limited knowledge … he’s right from a purely technical standpoint, because if you clip the negative phase, you will introduce distortion, no doubt. If you pre-limit the signal, you can somewhat avoid the problem, but then you’ve lost a percentage of modulation and you’re kind of back where you started.
Again with my limited view, the ‘magic’ of the Inovonics 222 is that it doesn’t do anything as a form of attenuation, like, say, an AGC does. Instead it somehow allows the positive signal peaks to come through stronger. I’m sure they wouldn’t be selling these things if that were easy to do. I’ve looked at the circuitry in its manual … not something I’d want to try and build. Besides, it’s probably patented.
I just thought: Really down and dirty basics (dunno if this is how a 222 actually works) … If you split up the signal into several different paths, one set 180 degrees out of phase so you end up with one positive-only and the other negative-only, then you can cut or boost modulation separately, and finally set them back in phase. If in addition, you have another clean signal brought through the same processing but with nothing done to it, then you can blend that with your differential signals and have a lot of control..
I wonder how much latency the 222 output has … hmm …
So, the consequences in any case is that while you do have modulation level differences between the negative and positive portions of the signal, which could be construed, in my view at least, as asymmetrical, you do not have any clipping, compression, limiting, or other coloring of the signal. Depends what you mean by “asymmetrical”.
See? He basically said that messing with peaks alone in half the signal would cause distortion except in the case of a pure sine wave, which makes perfect sense. IOW, you have to maintain full signal integrity, all the sound, throughout the process.
Anyway, if I can toy with some AU plugin processing and get a bit more positive phase modulation without affecting the negative phase, that might be worth some effort.
