Description/Specs
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.
