Bose Professional PowerSpace P4150+ Power Amplifier

Bose Professional PowerSpace P4150+ is a commercial power amplifier with integrated DSP designed for quick-turn distributed audio installations. It enables four-channel amplification and signal processing within a single rack-mounted unit for installers and system integrators. This makes it ideal for commercial environments where efficient setup, predictable performance, and flexible zone control are required.

The amplifier provides Class D amplification with load-independent outputs that support both low-impedance and 70/100V systems without bridging. Integrated DSP supports mixing, routing, equalization, delays, limiters, and loudspeaker presets through a browser-based configuration utility. Network connectivity enables configuration and monitoring using standard web browsers.

The P4150+ supports scalable commercial sound systems with simplified commissioning and intuitive end-user operation. Optional ControlCenter zone controllers allow local volume and source control. Automatic standby functionality reduces power consumption during idle periods in installed environments.
