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. The amplifier is capable of driving both low impedance and 70/100V loudspeaker loads directly.
Bose Professional ControlSpace Designer software — PowerMatch amplifiers can be fully configured using ControlSpace Designer software via the front panel USB connection, or the rear panel Ethernet connection. Using ControlSpace Designer software you can access additional features including: Parametric EQ stages, load sweep of each output channel and auto standby. ControlSpace Designer software is also used to integrate network model PowerMatch amplifiers into larger control and monitoring systems comprised of Bose Professional ESP processors and CC control centers.
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 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.

About the Bose Professional PowerMatch PM8500N Configurable Power Amplifier

The Bose Professional PowerMatch PM8500N is a highly advanced, network-configurable power amplifier designed for demanding installed sound applications that require both robust power delivery and sophisticated system control. It integrates powerful amplification with comprehensive DSP (Digital Signal Processing), network audio transport, and remote monitoring capabilities into a single rack-mountable unit. The amplifier utilizes PowerShare technology, which intelligently allocates available power across its output channels in real-time, allowing it to support demanding, dynamic program material without clipping or shutdown, even when driving lower impedance loads. This ensures reliable performance and protects loudspeakers from damage due to amplifier clipping.

At the core of the PM8500N is its extensive onboard DSP, which provides complete loudspeaker management functions including crossover filters, parametric EQ, dynamics processing, and delay. This eliminates the need for external DSP units in many system designs, simplifying the signal chain and enhancing system reliability. The amplifier supports audio networking via Dante, allowing for multi-channel, low-latency digital audio distribution over a standard Ethernet network, seamlessly integrating into modern AV-over-IP systems. Front-panel color touchscreen display and rotary encoder provide intuitive local control, while full remote configuration, monitoring, and control are achieved through dedicated software or a web browser interface.

Built for continuous operation in commercial venues, the amplifier features efficient Class-D power modules and a responsive cooling system to ensure long-term stability. Its comprehensive suite of protection circuits safeguards against thermal overload, short circuits, and DC offset. The combination of high-fidelity amplification, integrated loudspeaker processing, and networked audio/control makes the PowerMatch PM8500N a central, intelligent component for concert venues, houses of worship, conference centers, and any large-scale fixed installation where system performance, scalability, and remote manageability are critical priorities.
