Monoprice SS-4 Premium 4 Channel Speaker Selector with Impedance Protection, Supports 12-16 AWG Speaker Wire, Individual Zone On/Off

Control multiple speaker pairs from a single amplifier while keeping your amp protected—Monoprice SS-4 Premium 4 Channel Speaker Selector. Built-in automatic impedance protection prevents amplifier overloads and provides reliable operation. Power handling is 100 watts RMS per channel. Minimum amplifier impedance requirements: 5-ohm when four 4-ohm speakers are selected, and 6-ohm when using 8-ohm speakers. Accepts 12-16 AWG speaker wire and uses heavy-duty screw-type connectors for a secure physical and electrical connection. Each output zone has its own on/off button for independent control. Isolated left and right circuit grounds ensure safe compatibility with amplifiers that have floating grounds or are used in bridged configurations.
