Bose PowerMatch PM8500N Configurable Power Amplifier

The Bose® PowerMatch PM8500N configurable professional power amplifier provides concert-quality sound with a high level of scalability and configurability for fixed installation sound reinforcement systems. Ethernet-based networking enables configuration, control and monitoring, and 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—all in a reliable, proprietary design.

Bose PowerMatch PM8500N Features

• QuadBridge™ technology allows each 4-channel loudspeaker block to be configured as Mono, V-Bridge, I-Share or Quad modes
• Bose® ControlSpace® Designer™ software
• Auto-Standby/Auto-Wake function saves power
• Dual voltage and current feedback loop continuously monitors and controls both the current and voltage delivered to the loudspeaker load
• PeakBank™ 4-quadrant power supply enables higher power density while allowing the re-use of energy from reactive loads
• Fast-tracking PFC efficiently manages current drawn from AC mains, allowing the amplifier to drive loudspeakers to maximum output longer without power fluctuation
