Product Overview

The Bose Professional Power Space 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, Power Space+ 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 Control Center analog zone controllers — make operation easy for end users. For premium commercial applications, Power Space+ models provide amplification and DSP in one integrated, easy-to-configure package.
Applications

  • Retail stores
  • Restaurants and bars
  • Hospitality venues
  • Conference centers
  • Schools
  • Auxiliary zones

Key Features

150 watts per channel and works seamlessly with Bose Professional loudspeakers, DSPs, and controls to create complete commercial sound systems
Built-in DSP , including Smart Bass processing, routing, level control, delays, limiters, Bose Professional loudspeaker EQs, plus input and area EQs
Power Space 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 into low-impedance (2–4 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 Control Center CC-1, CC-2, and CC-3 analog zone controllers provide easy volume control and source selection

Amplifier - Front Panel

  1. Power switch – In/Out standby mode

  2.  Power LED Solid white LED indicates power is on. Blinking white LED indicates the unit is in auto standby mode.
    Solid red LED indicates a power supply fault. Blinking red LED indicates a thermal fault.

  3. Input 1, 2, 3, 4 signal LED – Each LED operates independently:
    Green LED indicates signal is present. Amber LED indicates signal is near clipping. Red LED indicates clipping.

  4. Output 1, 2, 3, 4 limit LED – Each LED operates independently:
    LED is amber when the amplifier is limiting the corresponding output due to exceeding the outputs’ VPeak or VRMS limits.
    LEDs will display solid red if an amplifier fault is detected.
    LEDs will blink red when all outputs are muted.

    1. Output attenuation 1, 2, 3, 4 – Output attenuators for each output. Turn the controls clockwise to decrease attenuation and counter-clockwise to increase attenuation.
    2.  Control Center – RJ-45 input connector for Bose Professional Control Center CC-1, CC-2, CC-3 analog zone controllers or CV41 4-to-1 converter only.
    3.  Mute – Contact closure connection where a short across the mute connector will mute all outputs. Mute polarity can be inverted by a DIP switch.
    4. Output – 8-terminal block connector for loudspeaker connections. Each channel can deliver up to 150 watts regardless of load into 4 Ω, 8 Ω, 70V, or 100V. Each output pair can be I-Shared.
    5. Ethernet – Connect amplifier to a switch or laptop Ethernet port to configure via the web-based configuration utility.
    6.  Music-on-hold – Dedicated 600 Ω music-on-hold interface.
    7.  Auxiliary output – Line-level auxiliary output.
    8. Input – Inputs 1 and 2 support balanced line-level inputs (Euroblock) or unbalanced inputs (stereo RCA). Inputs 3 and 4 are balanced inputs, and Input 4 also supports either a 600 Ω telephone paging input or a PTT/VOX dynamic microphone input.
    9.  AC inlet – Removing the AC cord when the amplifier is on is equivalent to powering down using the front panel power switch and is an acceptable power-down method.
