Product Features
• PowerMatch Class-D Amplifier
New, proprietary design combines Class-D efficiency with a dual feedback circuit that continuously monitors and controls both the
current and voltage of the output devices. This combination provides the PowerMatch amplifier with the highest-quality output power,
audio performance, reliability, and efficiency.
• QuadBridge™ Output Mode
Outputs can be configured as single, dual, or quad channel modes, which allows 4 kW of power to be allocated between 2 to 8
channels. These software-selectable configurations range from 8 channels at 500 watts, 4 channels at 1000 watts, 2 channels at 2000
watts, or mixed combinations. Dual or quad modes can drive either low-impedance or 70 V or 100 V loads.
• PeakBank™ Power Supply
Regenerative 4-quadrant power supply with fast-tracking Power Factor Correction (PFC) supports high efficiency, while improving the
peak burst power for superior transient response and current reserve for bass impact.
• 8 x 500 W from Single AC Mains Outlet
The PM8500 delivers 4 kW rated power from a single AC mains outlet, with greater than 75% conversion efficiency.
• Optimized Loudspeaker Processing
Integrated audio DSP for loudspeaker EQ, crossover, delay, and limiting. When used with RoomMatch™ and other Bose
loudspeakers, the presets provide all required signal processing with optimized protection limiting of self-powered loudspeakers.
