pioneer gm-d8500m class-d mono amplifier with 1200 watts max . power
pioneer s gm-d8500m mono class-d amplifier delivers 300 watts x 1 at 4 ohms or 600 watts x 1 at 2 ohms . that s enough to provide your subwoofer with tight efficient bass . speaking of efficiency the gm-d8500m s class-d design means less energy is wasted so you gain more power with a smaller profile . a built-in crossover and bass boost circuit let you dial in the bass content to suit your vehicle . a remote control for the bass boost is included . pioneer gm digital series amplifiers a commanding performance traditional analog amplifier designs are electrically and thermally inefficient -- converting as little as 30 of their electrical power into acoustical energy while the rest is wasted as heat . the dispersion of this excess heat requires large and heavy heatsinks increasing the size and reducing the installation flexibility of a traditional analog amplifier . pioneer s gm digital amplifiers utilize class-d amplifier technology to produce a compact high-power amplifier that converts as much as 70 of its input power to sound . serious sound . small space . the compact size of the gm digital amplifiers enables them to be installed in more places in your vehicle . if you want your system to be heard and not seen pioneer s gm digital series is the perfect choice as it s both small and powerful . the advanced circuitry of the gm-7500m model for instance is 45 percent smaller than its analog counterparts increasing your installation options in tight spaces . now you can enjoy superior audio amplification and installation flexibility from a compact product . bridge your system with digital the gm digital line of amplifiers has already earned an impressive reputation with pioneer retailers and customers alike . this year for the first time a full-range solution joins the digital line-up in the form of the gm-d9500f . you can now harness the compact powerful qualities of digital design to create a full-range fully digital system . gm-d8500m features 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 variable bass boost you can set the level between 0 and 12db with the remote . 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 -12 db 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 head unit 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 . gm-d8500m specs peak music power 1200 watts
