The BOSE's POWERMATCH PM4500 programmable professional power amplifier delivers concert-quality sound with a high level of scalability and configurability. Network configuration, control, and monitoring are all possible with Ethernet-equipped models, and an expansion slot accepts input from optional digital audio accessory cards. PowerMatch amplifiers combine a variety of Bose technologies to provide an unrivalled mix of performance, efficiency, and ease of installation—all in a dependable, unique design.

  • QuadBridge™ Technology allows the 4 available channels to be configured as Mono, V-Bridge, I-Share or Quad mode, allowing the total available power of the amplifier to be allocated to one or more output channels. 
  • The amplifier is capable of driving both low impedance and 70/100V loudspeaker loads directly.
  • 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).
  • Parametric EQ stages, load sweep of each output channel and auto standby.
  • ControlSpace Designer software is also used to integrate network model PowerMatch amplifiers into larger control and monitoring systems 
  • Auto-Standby/Auto-Wake function allowing the system to consume less power.
  • Dual voltage and current feedback loop circuit that continuously monitors and controls both the current and voltage delivered to the loudspeaker load.
  • Independent of power level and load impedance, the amplifier consistently delivers the widest possible dynamic range, frequency response and lowest possible distortion.
  • Regenerative 4-quadrant power supply enables higher power density while allowing the reuse of energy from reactive loads that is normally wasted in conventional Class-D designs. This highly efficient amplifier design delivers sustainable and repeatable low frequency response.
  • Fast-tracking power factor correction (PFC) provides superior transient response and functions at peak burst power much longer than conventional Class-D amplifier
