The DSP for quick-turn installations - the Bose CSP-428 commercial sound processor is 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
