This new amplifier is designed to combine high performance and high efficiency while producing high-fidelity audio Pioneer is known. The GM-D7400M digital mono amplifier, intended for powering large subwoofers, uses digital technology that makes it more efficient 80-95 percent than conventional Class A B amplifiers. The increased efficiency, the physical size of the new IT-compact and easier to install.
Class-D amplifiers, overcoming the inefficiencies of traditional Class-A or AB amplifiers. Pioneers Class-D amplifier transform very little power into heat so a higher percentage of the power supply (67%) is converted into the load. This gives a very compact amplifier, the less power consumption, high output power must produce. The class-D amplifier 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 both the input signal and a band of frequency components around the modulation frequency contains. A LPF (Low Pass Filter) then filters the high frequency pulses and the resulting amplified output signal is then sent to the subwoofer and or speakers.

Bass boost gives you more control over how your music sounds. It allows you the optimal bass level for each speaker sub connection with the GM-D7400M, so the tone controls from the control unit can do what they do best. And because this is selectable bass boost to the level at 0dB, 6dB, 12dB, or, whichever sounds best set up for you.
Built in the GM-D7400M is a very smart crossover network. It works like a gateway, routing the big bass signals (adjustable from 40 to 240Hz or lower, at -12dB octave) and filtering out higher-frequency signals that subwoofer. This optimizes the efficiency of your systems and provides the best sound quality.
