Bose Professional 803289-1110 PowerSpace P4300+ 4-Channel 300W Power Amplifier

The Bose PowerSpace P4300+ amplifier combines power and DSP into a 1RU, four-channel design for quick-turn installations. Part of a comprehensive platform of loudspeakers, controls, and software that help installers deliver premium commercial sound systems efficiently, Bose PowerSpace+ amplifiers feature a quick-setup workflow. An onboard configuration utility and intuitive browser-based UI present common tasks in a logical manner, so you can configure the system faster, reducing installation time while increasing setup accuracy. Once installed, Bose-proprietary algorithms offer predictable performance while optional interfaces — such as ControlCenter analog zone controllers — make operation easy for end users. For premium commercial applications, Bose PowerSpace+ models provide amplification and DSP in one integrated, easy-to-configure package.

 

Features

• 300 watts per channel and works seamlessly with Bose loudspeakers and controls to create complete commercial sound systems
• Built-in DSP, including SmartBass processing, routing, level control, delays, limiters, Bose loudspeaker EQs, plus input and area EQs
• PowerSpace configuration utility facilitates setup with an integrated web server and intuitive browser-based UI, including real-time control with signal and thermal monitoring Opti-voice paging provides a smooth transition between music and announcements
• Integrated features to simplify commercial installations: Dedicated input for 600-ohm telephone or mic paging, independent 600-ohm music-on-hold and line-level Aux outputs, and a NO/NC mute connection
• Load-independent outputs deliver full channel power to either low-impedance loads (4-8 Ω) or high-impedance (70/100V) loads without bridging
• I-Share outputs deliver 2x power level into low-impedance (2-8 Ω) or high-impedance (70/100V) loads by combining the current of both channels
• Auto-standby mode saves power when audio signal falls below a set threshold after 20 minutes, then wakes when audio returns
• Intuitive end-user operation — optional ControlCenter CC-1, CC-2, and CC-3 analog zone controllers provide easy volume control and source selection
