The Bose PowerMatch PM4250 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. 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 (PFC)
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.
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
The 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 re-use 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)
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 than conventional Class-D amplifier designs to satisfy the requirements of even the most demanding program material.
