Crown CDi 4000 2 Channel Stereo Power Amplifier with DSP Crown CDi Series Stereo Power Amplifier with DSP, 1000 Watts per Channel at Four Ohms and 70 Volts Output Crown CDi Series amplifiers are professional tools designed and built for installed sound applications. The series includes four models which are identical except for output power: CDi 1000, CDi 2000, CDi 4000, and CDi 6000. 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.
