Description
The Bose 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.
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.
- 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 AmpLink connectivity.
Why We Like This
Automatic music-to-page handling is useful in a business where staff need to make announcements without working through mixer settings.
