Crown CDi Series amplifiers are professional tools designed and built for
installed sound applications. The series includes three models which are identical except for output power: CDi 1000, CDi 2000, and CDi 4000. All are rugged and lightweight, and offer unmatched value in their class.
- Extremely versatile; rated for 2-, 4-, 8-ohm loads and 70V and 140V outputs.
- Switch-mode universal power supply.
- Intuitive front-panel LCD screen for quick, easy configuration.
- Onboard digital signal processing includes crossovers, EQ filters, delay, and output limiting.
- Up to 20 user defined DSP presets are available.
