|Bose PowerMatch PM8500 is a configurable professional power amplifier delivering concert sound quality for fixed installation sound reinforcement systems. Building on the ruggedness proven by 20 years of experience building Class-D power amplifiers for the automotive market, the PM8500 adds numerous new Bose patented technologies to simultaneously provide class-leading power, efficiency, sound quality and reliability.
PowerMATCH Class-D Amplifier – New, patent-applied 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 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 Household AC Mains –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.
Software Setup and Network Monitoring – All models have USB for Bose ControlSpace Designer programming, with PM8500N adding Ethernet network control and monitoring.
