What is 2-Source (A/B) Switching?

A/B or dual-source switching is a convenient feature that allows flexibility when you’re designing your whole-house audio system. With A/B switching, you can connect two sets of speakers and one source, and those speakers can be in same room or separate rooms. For example, speakers connected to source A could be in the living room and speakers connected to source B could be in the dining room. Then simply use the A/B switch to choose between the zones. Another option would be to connect two audio sources such as one amp and one receiver to play through one set of speakers and switch between the sources.
