I can see how with an input voltage near 2v, applying boost to frequencies that you can easily exceed/clip the 2v output stage. Don't most L/T circuits apply (approximately) a 12db/oct shelf filter? If so, it seems you'd to look at the maximum boost provided and provide an "allcut" filter to that same degree.
Say, the max boost was 15db, then you apply a 15db allcut filter to bring everything down to a doable output voltage - that should keep everything in check, right? I appreciate the concept of a true L/T circuit in that you're not really boosting anything, you're in effect cutting the higher frequencies to match the capability of the driver/amplifier limited excursion down low to smooth the frequency response.
BUT, what are we doing with an "L/T filter" with this device? I think it's applying boost down low, which will need some form of cut to keep the voltage in check, or am I just way off base here?
Seems like a little careful gain structure massaging is in need to make sure you're not clipping any part of the chain and maximizing the output capability of the amp.
And this reply was not aimed at you in particular Bosso, as you understand this stuff MUCH better than I do, but as someone who's trying to get his head around these devices for a future purchase, I want to make sure I'm understanding it's possibilities and limitations.
