The Bose Professional commercial sound processor simplifies quick-turn installations requiring music and microphone reinforcement with intelligent controls. AutoVolume adjusts sound levels in real time, adapting to changing ambient noise, while SmartBass ensures balanced bass that enhances any environment. With the time scheduler, you can automate source and level changes throughout the day, eliminating the need for manual adjustments. The network-based architecture allows for easy setup and real-time management via a browser interface or offline configuration utility. CSP supports up to five listening areas, managed by optional digital controllers or the ControlSpace Remote app, and features upgraded mixing functionality to blend multiple input sources, perfect for live microphone reinforcement. In conclusion, the Bose Professional sound processor is a versatile, efficient solution for high-quality sound reinforcement with user-friendly, network-based control.
FEATURES
Ensure optimal sound levels with AutoVolume, which adjusts in real-time to ambient noise, keeping music at the ideal level when paired with AVM-1 sense microphones (sold separately). Upgrade to the CSP-1248 processor to support up to five AVM-1 units, or choose the CSP- 428 processor for up to two units.
Deliver the perfect bass level—noticeable yet never overpowering. SmartBass delivers balanced bass, adapting to room acoustics and ear sensitivity for rich, non-overpowering sound, even at low volumes.
Struggle no more with uneven audio levels between different sources. Opti-Source Level Management, which adjusts the input of up to four sources for uniform volume. Opti-Voice ensures smooth transitions between music and announcements.
Take advantage of full mixing functionality, allowing input sources to be mixed and assigned to each listening area.
Zone the sound system to tailor audio for each area, creating up to five distinct listening zones. Control each with optional wall-mounted ControlCenter controllers or the ControlSpace Remote app.
Use the CSP Configuration Utility app to pre-configure devices, and export settings.
Right-sized connectivity for cost-effective commercial installation — 2 x 2 balanced analog I/O, 2 pair mono-summed RCA inputs, 8 control inputs, 1 control output, mute contact, Ethernet port, and Bose Professional AmpLink connectivity.
Bose Professional AmpLink output for simplified digital audio connection to compatible power amplifiers, reducing terminations, and related points of failure.
Simplify wiring with a network-based architecture, using Cat-5 or Cat-6 wiring and PoE capabilities. Supports both DHCP and static IP schemes for flexibility and scalability.
