The Bose Professional PowerSpace P4150+ 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 Professional 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, 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 Professional PowerSpace+ models provide amplification and DSP in one integrated, easy-to-configure package.
Take advantage of full mixing functionality, allowing input sources to be mixed and assigned to each listening area.
150 watts per channel and works seamlessly with Bose Professional loudspeakers and controls to create complete commercial sound systems
Built-in DSP, including SmartBass processing, routing, level control, delays, limiters, Bose Professional loudspeaker EQs, plus input and area EQs
PowerSpace configuration utility facilitates setup with an integrated webserver 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 Ω telephone or mic paging, independent 600 Ω 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 by combining the current of two channels
Auto-standby mode saves power when audio signal falls below a set threshold, 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
