Does anybody remember the theoretics of out-of-phase wiring of speakers?
(Out-of-phase was used a lot as a kind of surround-effect, and there are two ways to do it: with a third speaker: you connect two minus-cables from the amp to it; or with an add. pair of speakers - they get one plus-cable each from the amp, and their minus' are connected to each other.The result is that out of these speakers comes only what's different in the stereo-spectrum or something like that...)
This would make sense if you have 4 speakers connected to your system but the music is not mixed to 4-channels, to add some space.
I reckon it's not possible to do inside the mixing-software if the speakers are connected 'normal', huh?
I miss this effect!
Remember Out-of-Phase-Wiring?
You need 4 audio outputs to do this:
Lets say, you normally connect your speakers to your Pulsar mixers L & R main out.
Then you also connect the same outputs to 2 mono inputs on a mixer, where you can invert the fase.
The 2 channels on the second mixer must both be panned straight in the middle.
You invert the fase on one of the channels on the second mixer.
Now the only thing you get out of that second mixer is the difference between the first mixers L & R.
Connect the second mixer's channels to the outputs, that you connect to your rear speakers.
You can also experiment with panning the 2 signals comming in on mixer 2 a bit for the fun of it.
Be ware with mastering with this setup. Most often you will put the low frequenzies in the center. But with the low in center, you will get too little low in the rear speakers compared to a neutral soundscape.

And why not go the whole hog... and add another speaker in the front center, this time with both channels SUMMED (ie no phase inversion) into MONO.
So you now have the SUM of the channels in the front centre (signals that are in phase with each other), and the DIFFERENCE between the channels in the rear (signals that are out of phase with each other).
Hey presto! Dolby Pro-Logic.
