Provided by third party:

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. PowerMatch amplifiers utilize numerous Bose technologies to deliver an unprecedented combination of performance, efficiency and ease of installation - all in a reliable, proprietary design.

Key Features
  • QuadBridge technology
  • Auto-Standby/Auto-Wake function
  • Dual voltage and current feedback loop
  • PeakBank power supply
  • Fast-tracking power factor correction
QuadBridge technology
Allows each 4-channel loudspeaker block to be configured in Mono, V-Bridge, I-Share or Quad modes, allowing the total available power of the amplifier block to be allocated to one or more output channels. The amplifier is capable of driving both low impedance and 70/100V loudspeaker loads directly.
Auto-Standby/Auto-Wake function
When enabled, this function automatically enters/exits Standby mode, allowing the system to consume less power.
Dual voltage and current feedback loop
Proprietary design combines Class-D efficiency with a unique current and voltage 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.
PeakBank power supply
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
Efficiently manages the current drawn from the AC mains, allowing the amplifier to drive loudspeakers to maximum output longer without power fluctuation. PFC provides superior transient response and functions at peak burst power much longer to satisfy the requirements of demanding program material.
