Phase inverters to piece of gear
The speakers are wired in phase
Do i need "inverters" to match the output stages of one piece of equipment to another input stage?
Because some manufactors have either the output
1.) inphase or
2.) out of phase
"the output stage internally in putting out a out of phase signal:"
1.) preamp output is out of phase going to a eq units input
do i need a inverter to fix this?
2.) Eqs units output is out of phase to compressor input
do i need a inverter to fix this?

ITs a Polarity problem
in the input polarity and the output polairy
Output polarity VS the next piece of gear input Polarity
they are opposite Polaritys how do i fix this
Preamp output Polarity >>>>> EQ input Polarity
"Need to be matched"
EQ output Polarity >>>>>>>Compressors Polarity
" Needs to be matched"
Do i need inverters to match these Polaritys ?

Input polarity vs output polarity
i have to match them
Someone told me to Switch or Flip the wires around if the polarity
is not right

Some equipments output is REVERSED polarity and its not good going
into the next piece of gear with revered polarity

yea becase its Reversed polarity output and needs to be reversed
to be forward polarity

That some pro audio gear have REVERSED polarity or FORWARD polarity
OUTPUTS and it creats Phase problems and makes the signal sound
really THIN how do i fix this POLARITY problems
preamp polarity output
eq polarity output
compression polarity output

Just making sure if that was right without geting a ground loop or something
Because when you reverse the wires your puting the AC signal through
the GROUND of the circuit
gear#1 output hot >>>>>>>>>>>>>>>hot gear#2
ground>>>>>>>>>>>>>>ground
reversing the wires:
gear#1 output hot>>>>>>>>>>>>>>>ground gear#2
ground>>>>>>>>>>>>>>hot

yeah, you just got to think about it...
if you have to reverse the cable, it is because your ground wire is plugged into the positive jack on one piece of gear.
so when you reverse them, you are fixing this problem.

Walters is not seeking sense - just conversation. This exact same question was asked by Walters in another forum, and he received all the correct answers and corrections to his terminology that he needed.
