Is the Pass F2 Pase Inverting?

Zen Mod 23rd August 2010 06:36 PM

nope

Zen Mod 23rd August 2010 06:36 PM

yes , nope , yes

Zen Mod 23rd August 2010 06:37 PM

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

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

:clown:

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.

:cool:

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.

I truly don't understand. :confused:

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

:cool:

mine is!:)

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