Speaker switches can be used to create multiple zones from a single amplifier. Wired between the amplifier and speakers, a switch provides on/off control of two or more stereo speakers. A good example of this is a bedroom/en-suite bathroom setup where independent music in each zone isn't required, but on/off control of each zone is.
Most speaker switches are manual and require buttons to be physically pressed to turn speaker pairs on and off. However our Audioflow smart speaker switches are Wi-Fi enabled and can be operated via an app or even voice control.
