The SS‑4 Speaker Selector is a resistor‑based, impedance matching speaker selector used for connecting up to four pairs of 4‑ohm or 8‑ohm speakers, while maintaining a safe impedance load for your amplifier or receiver. Each pair of speakers can be independently turned on or off using push buttons on the front panel, with no need for worrying about amplifier loading.
Features:
Connect and safely control multiple speaker pairs with a single amplifier
Automatic impedance protection circuitry
100 watts RMS per channel power capacity
5‑ohm minimum amplifier impedance with four 4‑ohm speakers selected, 6‑ohm minimum with 8‑ohm speakers
Supports 12‑16 AWG speaker wire
Individual zone on/off buttons
Heavy‑duty screw‑type connectors
Isolated left/right circuit grounds provide a safe connection for amplifiers with floating grounds or bridged configurations
