Impedance Matching

• Power Handling: 100 watts RMS per channel
• Frequency Response: 20 Hz – 22,000 Hz (+0dB, -0dB)
• Wire Size Acceptance: Up to 14 gauge wire
• Dimensions: 1 7/8″ x 11 1/2″ x 7″

Maximum Number of Speaker Connections: 4 pairs (4 ohm minimum)

Minimum Amplifier Impedance with All Speakers Selected:

• All 8 ohm speakers connected and engaged: 6 ohms
• All 4 ohm speakers connected and engaged: 5 ohms

The SS4R is a resistor based, automatic impedance-matched 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
• Removable speaker connectors
• Easier installation  and firmer connections
• Heat-sink-covered resistors ; higher power-handling
• Venting above and below resistors
• Smarter design means higher power handling and longer life
