Bose CSP-428 Commercial Sound Processor

CSP-428 - Overview

• Features:

  • 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
  • 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; 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 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
