Pioneer’s Class-D amps transform very little power into heat so a higher percentage of the power supply (67%) is transformed into the load. This results in a very compact amp which needs less input power to produce very high output power. The Class-D amplifier’s PWM (Pulse Width Modulator) modulates the original audio input signal with a triangulated signal wave which has a much higher fixed frequency. The result is a digital signal which contains both the input signal and a band of frequency components around the modulation frequency. A LPF (Low Pass Filter) then filters out the high frequency pulses and the resulting amplified output signal is then sent to the subwoofer and\/or speakers.\u003c\/p\u003e","brand":"Pioneer","offers":[{"title":"Default Title","offer_id":34412662543,"sku":"R0057SFAR6","price":309.0,"currency_code":"RUB","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1721\/0361\/products\/GM-D8500M_angle_large_2710f443-6f94-48a3-8e05-fea04864ffb1.jpg?v=1484752268","url":"https:\/\/zubr.myshopify.com\/products\/r0057sfar6","provider":"zubr","version":"1.0","type":"link"}
