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?
 
ps- no, you don't need to worry about it.

God my life is sad right now.
 
has nothing to do with DC to AC


Its more of the gear is out of phase with eachother because of
phase mismatching of the output phases with the input phases

output phases with the input phases can be mis matched
 
EXAMPLE

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?
 
It's really polarity reversal, not being out of phase, if I'm getting you.

How do you know if they are reversed? Have you tested your system for absolute polarity? Have you tested all your gear?

A simple reverse-polarity cable will fix polarity issues.
 
Well isn't Polarity = 180 degrees phase?

Yes its a Polarity problem how can i fix this with 1/4 inch output jacks
going into 1/4 inch input jacks

Having Polarity differences

output polarity not the same going to the input polarity
 
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 ?

Sort of. It's hard to say how many degrees of phase shift you are introducing in a complex non-repeating wave form like a music track. Phase is time-based, a delay between two signals. A signal that has more than one frequency, and is delayed with respect to another identical signal may be phase-shifted 180° at one frequency, but only 150° at another, and 79.5° at yet another.

Polarity reversal changes the sign of the signal, making it + where it was -, and - where it was +. It is sort of the equivalent of 180° phase shift at all frequencies. But it is not phase shift.

All you have to do is switch + and - at one end of a cable, and it is polarity reversed.

How do you know?
 
What Major brand makes POLARITY units so i can change the polarity
of any output or any input polarity so i can match the input polaritys
with the output polaritys?
 
would INVERTERS do this?

Where can i but audio inverters or audio polarity units?

whats the brand names for theses units?
 
I don't know if anyone makes a multiple polarity reverse box.

I'm off to do something more fun than this, like eating a light bulb or pounding my nuts with a hammer.

Have a good day, walters!

Your problem is when you boost or cut the EQ you create some phase shift in the signal. Don't boost or cut on the EQ and you will be OK.
 
this is how it works
Phase is very important when wiring speakers. Positive going voltage will cause the speaker cone to move in a certain direction, which is usually forwards, at least two american and two british manufacturers have unfortunately adopted the opposite convention. It is essential that both speakers of a stereo pair, or all of the speakers of a particular type in a complete rig, are 'in phase', that is all the cones are moving in the same direction at any one time when an identical signal is applied. If two stereo speakers are wired up out of phase, this produces vague 'swimming' sound images in stereo, and cancellation of bass frequences. This can be easily demonstrated by temporarily connecting one speaker in opposite phase and then listen to the monosignal source, speach from radio is a good example. The voice will seem to come from nowhere in particular, and small movements of the head produce sudden large shifts in the sound source location. :)

So. if I play a brittish album (like The Beatles, The Who etc.) which way should I wire the speakers?

How do I do this?
 
Input Polarity Vs output polarity


Preamps input polarity
Preamps output polarity

EQ input polarity
EQ output polarity

Compressor input polarity
Compressor output polarity

The Polaritys can all be different and be mismatched

How do i fix this Polarity input and output problem?
 
Yea but how do i fix this problem?

You never told me this how do i fix this polarity input and output problem?
