So, I have a pair of subwoofers that I either connect with the Lx mini Pass xover set at 100hz hp and lp filters, or with a mini dsp xover set at 55 hz with a 24 db lp filter using a high level connection from the main amp’s outputs leaving the main speakers full range in this last setting.
And the issue is that both work very well with my xa25 amp. However, with the VFET amp. the high level connection does not function as intended, though I cannot get it to differentiate left and right channels, the subwoofers sound in mono. This is, having the same setup in the dsp mini for both amps. Is there something in the design of the VFET that would make this to happen? Thanks!

Well, I got it to work with the VFET, but don’t know why… the High Level connection at the amplifier output has a filter using a 1k resistor in series to bring the signal to low level. That is connected to the mini dsp inputs. I only inverted the connections in the amp., having the wire with the resistor connected to the black terminal post ínstese of the red one, and vice versa. Now is working. And why would that be?
which one?
N or P VFet iteration
or , first or second one
or - for God's sake, there are at least 5 PapaVFet amps, I'm totally lost if schematic is not shown, or detailed in some other way

damn, how many of this same threads are flowing around??

Manolo this is the third thread you have created on this topic, please use the reply option and stop creating new threads.I do not know what are you talking about. This is the first time I am posting about this issue and I consider it a fair question. And although I am an engineer like you I am not electronics one. And I am talking about the P VFET, the first one.
You created 3 separate threads on this topic, I assume accidentally.. LOL I merged two of them and deleted one, not sure how that happened, but it did.
