It also comes with three color knobs and cover to match your decor. Very satisfied as my sound is back to high fidelity. The instructions were clear also. Highly recommend.

A common approach is to set the receiver/amplifier to an appropriate baseline level, then use the wall control to reduce volume in that zone as needed. **Q: Where should the amplifier and speaker wires be connected?** A: Connect the speaker wires coming from the amplifier/receiver to INPUT, and connect the wires going to the speakers to OUTPUT. **Q: What is the purpose of impedance matching?** A: It helps prevent amplifier overload by keeping the overall speaker load at or above the amplifier’s rated impedance when multiple speaker pairs or controls are used, set the selector correctly. **Q: What should I check if the amplifier shuts down or audio becomes distorted?** A: Confirm amp to INPUT and speakers to OUTPUT, then verify the selector is set correctly and matches across all controls in the system. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very satisfied.
