Speaker selectors are the unsung heroes in the whole house audio chain, but these unassuming devices are critical to experiencing music throughout your home. A speaker selector connects to the amplifier, borrows power from that amp and shares it with multiple sets of speakers. Say you’re listening to Spotify in the kitchen but are moving to the garage or den and still want to hear the music. Speaker selectors include buttons designated to a particular zone. Press the button and the beat goes on, but there is more to speaker selectors than meets the ear. Speaker selectors can be single zone or multi-zone and, depending on the type of amp you have and the system you’re designing can include impedance matching protection to avoid overload issues.
