The DSP for quick-turn installations — Bose Professional commercial sound processors are part of a comprehensive platform that includes loudspeakers, controls, and software that help installers deliver premium sound systems efficiently. An onboard CSP configuration utility and intuitive browser-based UI provide a quick-setup workflow. Common tasks are presented 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 ControlCenter digital zone controllers and the ControlSpace Remote app — make operation easy for end users.
Right-sized connectivity for cost-effective commercial installation — 8 × 4 balanced analog I/O, 4 pair mono-summed RCA inputs, 8 control inputs, 1 control output, mute contact, Ethernet port, and Bose Professional AmpLink connectivity
CSP configuration utility with browser-based UI facilitates real-time display and control of levels, routing, thresholds, priorities, scheduled events, Bose Professional loudspeaker EQs, plus input and area EQs
Rear-panel Ethernet port for PC/Mac configuration; also allows for connection to networks supporting ControlCenter digital zone controllers and the ControlSpace Remote app
AutoVolume compensation continuously adapts zone output level based on ambient noise when paired with the Bose Professional AVM-1 sense microphone (sold separately)
Opti-Voice paging provides a smooth transition between music and announcements
Opti-Source level management monitors input level of up to 4 sources, maintaining consistent volume when switching sources
SmartBass processing expands performance and response at any listening level
AmpLink output for simplified digital audio connection to compatible power amplifiers, reducing terminations, and related points of failure
Intuitive end-user operation — optional ControlCenter CC-1D, CC-2D, and CC-3D digital zone controllers and ControlSpace Remote app provide easy volume control and source selection
