The Bose Professional 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 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.
-
300 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
