SWA500 AMPLIFIER

All three subwoofers are powered by an external Class D amplifier, the SWA500. It produces 500W Continuous into 4 Ohms. The BASH amplifier combines the fidelity of conventional Class A/B amplifiers with the efficiency of Class D amplifiers. The bottom line is high power, and cool, reliable operation with precise definition and low distortion. Plug-in data cards for each subwoofer, called SPEX Cards, preprogram equalization, infrasonic filter characteristics and power output that best matches

the subwoofer being used. Each SPEX Card also has specific power control circuitry tailored to each subwoofer’s require- ments for an even greater level of reliability. A SPEX Card installs easily, plugging into the back of the amplifier.
