The Bose PowerMatch PM8250 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
- Fast-tracking power factor correction
Features
QuadBridge technology
It allows each 4-channel loudspeaker block to be configured as 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.
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 a wide dynamic range, frequency response and low distortion.
Fast-tracking power factor correction
It 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 demanding program material.
