The DSP for quick-turn installations — Bose 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, Bose-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.

Bose Professional Commercial Sound Processor
