Same Powerful Output from a More Compact Amp
100 % of the power, 45 % of the size
The superior efficiency of a Class-D amplifier means higher power
output and greater compactness than an analog amplifier offers.
Efficiently Compact, Awesome Power
Class-D amplifiers overcome the inefficiencies of traditional
Class-A or AB amplifiers. 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.
Selectable 50Hz Bass Boost
Bass boost gives you more control over how your music sounds. It lets
you set the optimal bass level for each speaker/sub connected to the
GM-D8500M, so the tone controls from your headunit can do what they do
best. And because this is selectable bass boost, you can set the level
at 0dB, 6dB, or 12dB, whichever sounds best to you.
Built-In Crossover (40~240Hz Low-Pass Filter)
Built into the GM-D8500M 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 to that subwoofer. This optimizes your system's efficiency and
delivers the best possible sound quality.
Speaker Level Inputs
What, you DON'T own a Pioneer headunit? Well, we won't hold it against
you. In fact we'll even help you build onto your system. The GM-D8500M's
speaker level inputs allow you to connect your OEM unit (or any unit
that doesn't have the typical RCA-type inputs) without having to buy
add-on adapters. So, the install goes faster, you save money, and you've
got a Pioneer amp in your vehicle.
