Description

The Bose Professional 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 to a variety of applications including retail, restaurants, and hospitality industry.

The processor's I/O options include 2x2 balanced analog I/O, 2 pairs of mono-summed RCA inputs, 8 control inputs, 1 control output, mute contact, Ethernet port, and Bose AmpLink connectivity. An onboard CSP configuration utility and intuitive browser-based user interface help you set it up. Common tasks are presented in a logical way, so you can configure the system faster with accuracy and reduced setup time.

Once installed, the proprietary algorithms provide predictable performance, while separately sold digital zone controllers and the ControlSpace app make operation even easier for the end user.

  • Right-sized connectivity for cost-effective commercial installation: 2x2 balanced analog I/O, 2 pair mono-summed RCA inputs, 8 control inputs, 1 control output, mute contact, Ethernet port, and Bose AmpLink connectivity
  • CSP configuration utility with browser-based UI facilitates real-time display and control of levels, routing, thresholds, priorities, scheduled events, Bose loudspeaker EQs, plus input and area EQs
  • Rear-panel Ethernet port for PC/Mac configuration 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 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 on supported Bose loudspeakers
  • Bose 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 (sold separately) digital zone controllers and ControlSpace Remote app provide easy volume control and source selection
