Pass F2

Is the Pass F2 Pase Inverting?

 

[Zen Mod]

nope

 

[Zen Mod]

yes , nope , yes

 

[Zen Mod]

neg end of speaker is going to live output , pos end of speaker is going to cold output

so ........ really and still - nope

I think the speaker polarity is not of much concern.
Given the fact that F2 is common source, to me it is inverting.

So........yep. 🙂

By that argument, regular amplifiers usually phase invert
several times.

If you treat the red output terminal as + and the black output
terminal as - then the signal to the speaker is in phase with
the input.

 

[Netlist]

I truly don't understand. 😕

 

[Nelson Pass]

The black terminal is the active output. The red terminal
is ground.

[vitalstates]

mine is!🙂

 

[Netlist]

I see. I simply looked at the amp, without taking the speaker polarity -which indeed can always be inverted- into account.

 

[Puffin]

So, It is?

I have been using mine with Red to Black and Black to Red. From what Nelson says this seems to be correct.

 

[Zen Mod]

yes
