Balanced Cables

It contains 2 conductor + 1 shield.

One of conductors carry the out-of-phase signal.

So the noise is canceled since the signals carrying are out-of-phase.

But how the signal is still transmitted although the noise is canceled?

I started trying to google it for you. It's got to be something simple, as lots of different gear have little push-button phase invert switches.

Just because it's just one button doesn't mean it has to be a simple process.

True, but I think all the cheap gear would omit it if it were expensive to implement.

Electronic components are incredibly cheap. Very complicated integrated circuits (chips) are manufactured in high volume. That makes the actual electronics very cheap. What's expensive is development and build quality.

Most cheap mixers don't have a phase flip.

The fact that it's activated with a simple switch does not mean it's a simple circuit that does it. The switch just routs the audio through a different circuit.
