DD Audio SS4b


Sound Quality Rivaling Class AB Amps: The SS4b is a discrete circuit full range class D amp that can crank out over 350 Watts per channel at 2-ohm stereo, with less than 1% THD N. All this power fits into an SS chassis measuring only 6.875″ wide by 11.81″ long. By using discrete class D circuitry instead of a chipset we were able to get ultra-low distortion AND high power, contrary to the majority of small chassis class D amps on the market today. Not only does the sound quality of the SS amps trump other class D designs, they rival high-quality class AB designs. Take the SS amp challenge, compare the sound of an SS amp to similar power class AB amps and you will experience the future of high efficiency AND high fidelity. Versatility: SS amps feature individually selectable high pass and low pass crossovers with frequency bands from 50Hz-5kHz, making them adaptable to virtually any system configuration. We used heavy duty set screw blocks for speaker and power terminals to ensure connections are solid and durable. SS amps are smaller, more powerful, generate less heat, and just sound better than other class D amps on the market. This makes them the ideal choice for today’s space cramped interiors.
