Key Features New IC and MOSFET Unlike conventional amps that contain individual PWM modulators and ICs mounted separately, our new Class-D amplifiers integrate those capabilities in the more compact form of a single newly developed IC with built-in PWM modulator. Also, with power MOSFET extra-effective at dissipating heat, these Pioneer amps are brilliant combinations of advanced circuitry, space-efficient design and light weight. More Impact Made More Compact. A Class-D amplifier isn’t just more powerful than preceding amplifiers — it’s also much more compact. Powered up 33% — Slimmed down 57% 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 is transformed into the load. This results in a very compact amp which needs less input power to produce very high output power. Dial in the Desired Boost. Bass Boost can be set to levels between 0 to 12 dB for optimal bass levels according to preference and music style. This precise control can enhance the overall balance and impact of all kinds of music. The GM-D8500M allows this variable adjustment via wired remote knob and the GM-D7500M allows adjustment in three steps (0 dB/6 dB/12 dB) via the bass boost volume control on the amplifier’s side panel. GM-D8500M Number of Channels Mono Max. Wattage (4 Ω) 600W x 2 Max.
