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. PowerMatch amplifiers utilize numerous Bose technologies to deliver an incredible combination of performance, efficiency and ease of installation.
- Auto-standby function
- Dual voltage and current feedback loop
- Fast-tracking power factor correction
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.
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.
