Description

Details

The Crown CDi 4000 Power 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.

The CDi 4000 Power Amplifier features an intuitive front-panel LCD screen to guide installers through their configurations. CDi amplifiers also offer 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.
