The AUDIOflow S3-4Z speaker switch is designed for flexible multi-room audio control. You can connect up to four pairs of speakers to one amplifier and select which zones are active using front panel buttons, the AUDIOflow app (iOS/Android), or Amazon Alexa voice control.
This switch is ideal for homes that need audio management across spaces like a lounge, kitchen, snug, and garden. It supports impedance matching by wiring zones A+B and C+D in series, with both pairs in parallel, making it safe for most amplifiers when used with 8-ohm speakers. The S3-4Z is rated for up to 300W at 8 ohms, and includes features like contact closure integration for smart home systems.
