Crown CDi 4000 Power Amplifier

The Crown CDi 4000 Power Amplifier is a solid-state 2-channel power amplifier designed for installed sound applications. Featuring an intuitive front-panel LCD screen and a switch-mode universal power supply, it provides 1200W output power at 4 ohm and offers onboard digital signal.

The Crown CDi 4000 Power Amplifier is a professional tool designed and built for installed sound applications. The Crown CDi 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.

This 1200W Power Amplifier features an intuitive front-panel LCD screen to guide installers through their configurations. The Crown CDi 4000 Amplifier 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.

In addition, the Crown CDi 4000 2-Channel Power Amplifier comes with a switch-mode universal power supply. The outputs are useable as dual or bridged-mono modes of operation. The bridged-mono mode bridges the outputs to provide increased output voltage. The Crown CDi 4000 2-Channel Power Amplifier is protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature; chain destruction phenomena; excessive output current, and input overload damage.
