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
