Bose PowerSpace P4300+ Versatile Power Amplifier | 803289-2110

The Bose Professional PowerSpace P4300+ is a high-performance 4-channel power amplifier with integrated DSP, designed for commercial audio installations such as retail stores, restaurants, hotels, conference rooms, and educational facilities. It combines amplification, signal processing, and system control into a compact 1U rack-mount design for efficient installation and reliable operation.

The amplifier delivers 300 W per channel and supports both low-impedance (4–8 Ω) and high-impedance (70V/100V) speaker systems without requiring bridging, providing flexible system design for multi-zone audio setups.

Built-in DSP includes SmartBass processing, routing, delays, limiters, and Bose loudspeaker EQ presets, allowing installers to optimize sound performance for different environments. Configuration is performed through a browser-based interface with an integrated web server, simplifying system setup and monitoring.

Additional features such as Opti-Voice paging, music-on-hold output, and auto-standby power management make the PowerSpace P4300+ an efficient solution for professional background music and paging systems.
