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. Clearer Sound, Less Distortion. More conventional Class-D amplifiers have had advantages in energy efficiency and compactness, but not sound quality. They have been useful mainly for sound pressure-oriented subwoofers. So Pioneer devised new circuitry, carefully selected electronic parts and provided for more fine-tuned acoustic capabilities for its new Class-FD amplifiers. The results: high-quality, clearly localized sound throughout the full frequency spectrum from a more compact amplifier. GM-D7500M Number of Channels Mono Max. Wattage (4 Ω) 400W x 2 Max.
