Pioneers Class-D amplifiers transform very little power into heat, and as such, a higher percentage of the power supply is transformed into the load. This results in a very compact amplifier which needs less input power to produce very high output power. Witness how GM-D8500M overcomes the inefficiencies of conventional Class-A or AB amplifiers.
PWM (Pulse Width Modulator)
To modulate the original audio input signal with a triangulated signal wave which has a higher fixed frequency, resulting in a digital signal which contains both the input signal and a band of frequency components around the modulation frequency.
LPF (Low Pass Filter)
To filter out high frequency pulses before resulting amplified output signal is sent to the subwoofer and/or speakers.
Built-In Crossover
To optimise efficiency and deliver the best possible sound quality with a smart crossover network (adjustable from 40 to 240Hz or lower, at -12dB/octave). It works like a gateway, routing the big bass signals and filtering out higher-frequency signals to that subwoofer.
Variable Bass Boost
To allow more control over how music sounds through selectable bass boost at levels between 0dB to 12dB via a wired remote knob.
