Open Box — InwallTech SS-4R Ultra Cooling Speaker Selector 4 Pairs

Main Advantages of InwallTech Speaker Selectors are:
Removable Speaker Connectors (No Extra Cost) –Easier Install and firmer connections
Heat Sink Covered Resistors (No Extra Cost)….other makers provide inadequate cooling –Higher (honest) Power Handling
Venting ABOVE and BELOW Resistors (No Extra Cost) — Smarter design = Higher power handling and longer life

The SS4R is a resistor based, automatic impedanced matching speaker selector used for connecting 4 pairs of speakers while maintaining a safe impedance load for your receiver. Each pair of speakers can be turned on or off independently in any combination without concern for amplifier loading.

-Connect and safely control multiple speaker pairs.
-Automatic impedance matching protection circuitry engages without the need for user involvement.
-Individual room on/off pushbuttons
-Heavy-duty screw-type connectors are removable and accept up to 14 gauge wire
-Isolated left/right circuit grounds provide safe connections for amplifiers with floating grounds or bridged configurations
-High quality construction throughout provides excellent reliability,
accurate noise-free switching and years of trouble free operation
-Rubber feet prevent scratching and keep selector in place during operation
