The P4300+ is a four-channel amplifier delivering 300 watts per channel, designed to integrate seamlessly with Bose Professional loudspeakers, DSPs, and control systems for complete commercial sound solutions. It features built-in DSP with SmartBass processing, routing, level control, delays, limiters, and optimized Bose loudspeaker EQs, along with input and area EQs for precise tuning. Setup is simplified through the PowerSpace configuration utility via an integrated webserver and intuitive browser-based interface, offering real-time signal and thermal monitoring.

Additional features such as Opti-Voice paging ensure smooth transitions between music and announcements, while dedicated inputs for 600 Ω telephone or mic paging, music-on-hold output, auxiliary outputs, and mute connections streamline installation. Load-independent outputs deliver full power to low-impedance (4–8 Ω) or high-impedance (70/100V) systems without bridging, and I-Share capability combines channel current to provide double power when needed. An auto-standby mode enhances energy efficiency, and optional ControlCenter zone controllers allow simple end-user volume and source control.
