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
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)
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
PeakBank™ power supply - Regenerative 4-quadrant power supply enables higher power density while allowing the re-use of energy from reactive loads that is normally wasted in conventional Class-D designs
The Bose® PowerMatch PM4500 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, 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.
