Most of us are familiar with connecting speakers to a stereo system: you pull the two conductor speaker cable, connect the red wire to the red terminal on the amp, connect the black wire to the black terminal on the amp, repeat on the right speaker, and then repeat on the left speaker. It’s all pretty simple and straight forward… and it works great for stereo audio in a single room.
But what do you do when you need to distribute audio to speakers in multiple areas? Or if the application won’t really support left and right stereo audio?
