The Crown CDi series includes three models which are identical except for output power: CDi 1000, CDi 2000 and CDi 4000. All three are rugged and lightweight, and offer unmatched value in their class. ''CDi'' stands for Contractor Digital Intelligence - geared with contractors in mind for commercial installed sound applications.
The Crown® CDi 1000 power amplifier is a professional tool designed and built for installed sound applications. Rugged and lightweight, it offers incredible value in its class. It features an intuitive front-panel LCD screen to guide installers through configurations, and also offers onboard DSP for loudspeaker signal processing. Other features include a switch-mode universal power supply, useful function indicators, proportional-speed fan-assisted cooling, removable Phoenix-style inputs, barrier strip outputs for low-Z or 70V/140V loads, short-circuit protection and more. Your investment in a Crown CDi-Series power amplifier is backed by Crown's Three-Year, No-Fault, Fully Transferable Warranty.
