Bose PowerSpace P4300+ Power Amplifier

Product Type:

Brand: Bose

SKU: PowerSpace P4300+

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.

  • 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 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-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 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
