The Bose® PowerMatch PM8500 configurable professional power amplifier provides concert-quality sound with a high level of scalability and configurability for fixed installation sound reinforcement systems. Ethernet-equipped versions enable network configuration, control and monitoring, while an expansion slot supports input from optional digital audio accessory cards. PowerMatch amplifiers utilize numerous Bose technologies to deliver an unprecedented combination of performance, efficiency and ease of installation in a reliable, proprietary design. Available in two versions, the PM8500 provides USB connection for single-unit setup and control using Bose ControlSpace® V3.0 or higher software, while the PM8500N adds Ethernet connectivity for network control and monitoring of multiple “N” version amplifiers.


  • QuadBridge™ technology allows each 4-channel loudspeaker block to be configured as Mono, V-Bridge, I-Share or Quad modes, allowing total available power of amplifier block to be allocated to one or more output channels
  • V-Bridge and Quad modes drive either low impedance or 70/100V loads
  • Bose® ControlSpace® Designer™ software
  • PowerMatch amplifiers can be fully configured using ControlSpace Designer software via the onboard front panel USB connection, or the rear panel Ethernet connection (network models only)
  • ControlSpace Designer software allows access to additional features including: Parametric EQ stages, load sweep of each output channel and auto standby
  • ControlSpace Designer software allows integration of network model PowerMatch amplifiers into larger control and monitoring systems comprised of Bose ESP processors and CC control centers
  • Auto-Standby/Auto-Wake function, that when enabled, automatically enters/exits Standby Mode, allowing system to consume less power
  • Dual voltage and current feedback loop
  • Proprietary design combines Class-D efficiency with unique current and voltage feedback loop circuit to continuously monitors and controls both current and voltage delivered to the loudspeaker load
  • PeakBank™ power supply
  • Regenerative 4-quadrant power supply enables higher power density while allowing re-use of energy from reactive loads to deliver sustainable and repeatable low frequency response
  • Fast-tracking power factor correction (PFC)
  • Efficiently manages current drawn from AC mains, to allow maximum output longer without power fluctuation
  • PFC provides superior transient response and functions at peak burst power longer than conventional Class-D amplifier designs
