POWER: SLS100 is rated at 100 Watts peak, with minimal bass roll-off. Adjustable jumpers add up to eight pairs of 8 ohm speakers simultaneously depending on the load your amp can handle. VOLUME CONTROL: The controls allow you to switch the volume up or down. During setup, set the source volume to its optimum level, then the volume control turns the sound down to inaudible levels. IMPEDANCE PROTECTION: This feature of SLS100 assists in stabilizing the ohm load going back to the amp or receiver with parallel connections to avoid overheating and damaging the amplifier. SOUND QUALITY: Wire a 12-step linear slider knob for pop-free control and a wide range of listening volumes. Precision electronics provide low distortion and ruler flat frequency response in a stereo system. DESIGN: For dedicated audio zones, the décor plates install easily into a wall and work with almost any system. It accepts up to 14 gauge wiring and includes screws, and trim plates. The OSD Screwless Volume Control Slider is a unique design to switch the volume of speakers to an almost inaudible sound, and off completely.
