Phase Shift

Phase Shift is for stereo waves. This effect gives you the same
result as reversing the positive and negative speaker wires of
one stereo speaker. Normally, stereo speaker cones move in and
out similarly (in phase). When you reverse the wires of one
speaker, it reverses the phase of that speaker so that when a
phase pushes one cone out, the other cone is moving back. This
creates what is called an ambient effect.

Phase Shift lets you reverse the phase of one channel without
changing the speaker wires. Try it out and hear the difference.
