The Bose PowerSpace P4150+ is a professional 4-channel Class-D power amplifier with integrated DSP, engineered for commercial audio systems requiring flexible control, efficient installation, and reliable performance. Delivering 4 x 150W of output power in a compact 1U rack format, it combines amplification, signal processing, and system control into a single streamlined solution.
Designed as part of the Bose PowerSpace ecosystem, the P4150+ enables installers to deploy high-quality multi-zone audio systems with reduced complexity, making it ideal for hospitality, retail, corporate, and education environments.
The PowerSpace P4150+ provides four independent 150W output channels, allowing multiple zones or speaker circuits to be powered from a single unit.
This makes it particularly effective for:
By consolidating four channels into a single amplifier, it reduces rack space and simplifies system design.
A key advantage of the P4150+ is its load-independent output design, allowing full power delivery to both low impedance (4–8Ω) and high impedance (70V/100V) loudspeaker systems without requiring bridging.
This enables:
This flexibility is particularly valuable in commercial installations where different zones may require different speaker configurations.
The P4150+ features a comprehensive onboard DSP engine, eliminating the need for external signal processors.
Key DSP functions include:
This ensures optimised sound quality and system protection across all connected loudspeakers.
A standout feature of the PowerSpace P4150+ is its integrated web-based configuration utility. The onboard web server allows installers to configure the system via a browser interface, enabling:
This significantly reduces installation time while improving setup accuracy.
The P4150+ is designed with commercial environments in mind, offering advanced paging and integration capabilities:
These features make it suitable for environments where communication and system integration are essential.
The amplifier includes Bose I-Share functionality, allowing two channels to be combined to deliver increased power to a single output when required.
This provides:
Utilising Class-D technology, the P4150+ delivers high output with improved efficiency and reduced heat generation.
Benefits include:
An automatic standby mode further improves efficiency by reducing power consumption when no signal is present.
The P4150+ is designed for seamless integration into commercial AV systems, featuring:
It also integrates with Bose ControlCenter wall controllers, allowing end users to manage volume and source selection locally.
Housed in a standard 1U 19-inch rack format, the P4150+ offers high power density in a compact footprint. Its lightweight yet robust design allows for straightforward installation in racks and equipment cabinets.
Front-panel LED indicators provide clear system monitoring, including signal, clip, and protection status.
The Bose PowerSpace P4150+ is widely used across commercial audio installations:
Its combination of DSP, multi-channel output, and flexible integration makes it particularly suited to multi-zone systems.
